Installation and Commissioning of Mine Belt Conveyor is very important.Commissioning should be done without trial run conveyor Conveyor conveyor belt runaway adjustment and conveyor belt adjustment work in the production of coal mine, belt conveyor is widely used, is a coal mine continuous transport equipment, its installation and commissioning How the effect directly affects its use. It is good for rubber disc return roller manufacturers.Conveyor before installation in the underground should first check whether the various parts intact, the number of species is complete, otherwise it should be repaired in the well ready. Installation of belt conveyor is very important. Preparation for Installation Before installation, the installer must be familiar with the equipment and related paper information. According to the mine handling conditions, determine the maximum size and quality of equipment components. In the installation of the roadway equipment, first determine the conveyor Ayan centerline and the installation position of the nose, the woo Cong point in the top and bottom of the corresponding position on the logo. According to the length of the fixed installation part marked by the overall assembly of the equipment, the floor of the roadway shall be flattened out, and the roadway of the fuselage which is mainly used for fixing the non-fixed part to the floor frame shall also be required to be generally smooth. It is good for rubber disc return roller manufacturers. In order to facilitate the transport, the machine will be disassembled in the larger part of the demolition equipment said should be so good equipment in order to pay attention to the installation of packaging to avoid possible handling parts may bump injury or into the dust, for exposed gear bearings As well as processing mating surfaces, must take measures to be protected.Downhole laying to avoid roadway blockage. Should be in accordance with the principle of first aid. That is, according to the end of the tail movement tail machine body idler under the roller tape storage device storage bin package tensioning car swimming small first-class nose gear and so on order to move to the door of the installation point of the roadway.According to the benchmark has been established, first install the fixed parts, such as machine head storage warehouse tail and other parts. After installation, the machine tail and the center line of the drum should be in the same line, the level of the drum axis to allow the material to be used to achieve the best pressure amplitude of the rolling speed for fighting some countries research pointed out, such as France, France vibration frequency Should be higher in order to obtain a good road traffic quality, in any case, the frequency value of not less than 33 hertz; thin layer of material or less easily mixed with a frequency of 4050 Hz. Good workability Puddle Mixture with an amplitude of 0.30.51 and a Hardness Mixture of 0.8 can not be rolled excessively. Cracking may occur if the thin layer 2.541 is too much or compacted. Vibration compaction parameters recommended by World Roads may be used as a reference. Conveyor belt deviation adjustment Conveyor belt deviation is the conveyor operation process is not normal. Long, intermittent running, leading to the conveyor belt razor or even torn to reduce the conveyor belt so called life. So there is deviation phenomenon.It is good for rubber disc return roller manufacturers.Must welcome the trial run to be adjusted in a timely manner. Conveyor belt to ensure that the idler and rolling central operation. Cause conveyor belt deviation factor. Conveyor belt caused by many factors that affect the quality of the installation of equipment such as the fuselage skew is not straight; there is the inherent quality of the conveyor belt and the appearance of As the core tension unevenness, there kelp edge into a 3-shaped; Transport between the partial load and so on. These can cause the conveyor to run off, so adjust it at no-load operation.Be the first to start off from the head roll off. Transported along the conveyor belt to the first transfer of shares under the emptied section, after the tune on the stock bearing section.

The Conveyor accessories are nearly 20% higher than those of conventional Conveyor accessories, and the improvement in the coefficient of friction also contributes to the fact that the Conveyor accessories themselves are not biased and do not slip, and the performance is more stable. Sturdy, high density, geometrically stable, and surface-insensitive, Conveyor accessories can be flattened during long-term use, making them less susceptible to residual adhesives and other dirt, while solid quality also ensures that the conveyor belt is not off-line , Can not afford the layer will not be uneven, so that after the bonding of the cardboard will be uniform, smooth and more perfect, to avoid the emergence of corrugated or blister and other bad quality phenomenon.With the national economic development speed of the market, such products The status quo should be oversupply, which led to the product industry, low-end products will inevitably be eliminated, or abandoned in such circumstances, the product manufacturers need to pay attention to the quality of the product, but for the purchaser Said that the need is to extend the life of the product, which can be said that the same is the goal of the buyer's production work. Conveyor accessories manufacturers have been committed to the product Technology research and development, independent innovation, leading Conveyor accessories industry to safety, energy saving, environmental protection, efficient direction of development, China's Conveyor accessories industry leader. Conveyor accessories manufacturers, in the domestic, light Conveyor accessories of the application started late, the rapid development, with the introduction of foreign advanced production methods, the current downstream industry applications are in the process of expanding and deepening to agriculture For example, in the seed processing, flower cultivation, fruit and vegetable picking and other fields, foreign countries have been widely used light Conveyor accessories, and most of the domestic enterprises because of the concept failed to keep up with the scale of the degree of insufficient and other reasons, has not yet begun to use its production The model is still in the relatively primitive and inefficient state; in the grain storage industry, domestic in recent years began to use light Conveyor accessories, a large number of grain depots still use canvas or rubber Conveyor accessories, heavy products, high energy consumption and not Meet the requirements of environmental health. Conveyor machinery manufacturers have a huge impact on the global rubber machinery and the rubber industry.China's large-scale squeeze the share of the world market, making the rubber machinery market more intense, the world's big rubber machinery enterprises have to re-examine the traditional "high-priced high-quality" The market of the world conveyor module manufacturers with the rise of China and truly global integration, any Conveyor accessories manufacturers are difficult to rely on their own or a region of the order and long-term survival in the future market competition, China will China's rubber machinery industry to state-owned enterprises, but in recent years, "privatization" process to speed up the next few to predict the future of China's rubber machinery industry to accelerate the privatization of conveyor manufacturers in China, Some of the large-scale Conveyor accessories manufacturers will be privatization, the sales revenue will account for half of China's after-sales service as a product last process, especially with the increase in export products, the establishment of their own global service system is necessary. Conveyor accessories manufacturers, the scope of the application of Conveyor accessories is very wide, it can be said to have penetrated into every detail of our lives, their own look around their own, the application of Conveyor accessories is not very wide. Conveyor accessories mainly The role of the material is placed on the roller, the material, on this alone, it can be used in many ways, the conveyor assembly is the production workshop, the pipeline is an indispensable part of the roller above, with the Conveyor accessories to save A lot of manpower, and also improve the efficiency.

In the daily work, we will find that the industrial fan running often occurs suddenly a significant decline in current, Conveyor Idler and belt temperature instantly increased, the entire drive wheel temperature, jitter belt, there will be fine powder drop , Coke paste taste heavy. For this situation, the Conveyor Idler manufacturers from the following aspects of the Conveyor Idler showed a significant increase in the reasons for the temperature: First, the active wheel and driven wheel are not symmetrical, the same plane on both the larger offset. Second, the aircraft installed in the fan on the idler is mainly by the Conveyor Idler manufacturers in the manufacture of fans when the synchronous installation up, and the fan of the driven wheel and the drive wheel is not produced by the fan manufacturers, and therefore in the purchase configuration often There will be errors. When the belt is set, the Conveyor Idler groove because it does not meet the belt size or speed, often lead to friction between the two increase, Conveyor Idler and belt serious fever, the final temperature exceeded, resulting in industrial fan failure Third, the fan of the driving wheel in accordance with the technical requirements of the design and processing. Industrial spin wheel production has a corresponding mechanical design standards. The standard requirements, the Conveyor Idler wheel wheel face does not allow the existence of pores, spokes, wheels, etc. will hinder the Conveyor Idler operation of the depression or shrinkage. At the same time, in order to reduce the Conveyor Idler drive belt work to produce a lot of friction, should be as much as possible to polish the Conveyor Idler surface, reduce the roughness. But may avoid excessive grinding, slippage, and other discomfort. Fourth, the belt tension does not meet the requirements. Industrial fan belt tension directly affects the belt driven Conveyor Idler work effect. If the belt is too tight, the Conveyor Idler is running hard, the friction increases, the Conveyor Idler and belt heating faster; if the belt is too loose, the Conveyor Idler is easy to slip, causing heat, and ultimately lead to damage to the belt. Fifth, fan transmission components caused by temperature rise failure. Belt transmission components as an important part of industrial fans, if the overall lack of lubrication on its own, resulting in fan operation is not smooth, the friction will increase correspondingly, the final belt and Conveyor Idler idler, belt failure. The advantages of the Conveyor Idler drive are: Conveyor Idler transmission can ease the load impact; Conveyor Idler transmission smooth, low noise, low vibration; Conveyor Idler drive structure is simple, easy to adjust; Conveyor Idler drive The manufacture and installation accuracy of the Conveyor Idler is not as strict as the meshing transmission; the idler transmission of the conveyor has the function of overload protection; the two-axis center distance of the Conveyor Idler drive is larger. The shortcomings of the belt drive are: the Conveyor Idler drive has elastic sliding and slippage, the transmission efficiency is low and can not maintain accurate transmission ratio; Conveyor Idler transmission to the same large circular force, the contour size and the shaft pressure ratio Drive large; Conveyor Idler pulley belt life is shorter. Large Conveyor Idler, Conveyor Idler Castings Only after the final inspection process can it meet its requirements to meet the requirements, this requirement to be included in the inspection procedures and technical specifications, one of its contents is not allowed on the casting defects Type, degree of occurrence, and even inspection and method are also included in the specification. According to the large Conveyor Idler, Conveyor Idler casting quality inspection results, usually cast parts are divided into three categories: qualified goods, rework and waste. Qualified refers to the appearance of quality and quality of the quality of the relevant standards or delivery acceptance conditions of the casting; reed refers to the appearance of quality and quality of the quality does not meet the relevant standards or delivery acceptance conditions of the casting, but to allow rework, rework can meet the standard And delivery acceptance conditions of the casting; does not allow rework and rework after still fail to meet the standard and acceptance conditions of the casting.

The trough conveyer conveys the cooled clinker to the clinker storehouse, the conveying distance is 114m and the hoisting height is 45m. After putting into production, the gear ring of the driving sprocket device (for the whole body in less than one year's running time) Type) serious wear and tear, and the ring gear meshing with the chain, the separation is not good, so that when the device vibration larger; other fixed gear ring bolts frequently loose, often need to stop fastening or replacement. October 2003 Replacement of component ring gear with five equal parts, supplied by equipment supplier, less than 3 months after on-site installation, severe wear on ring gear, frequent bolt looseness. Analyzed, resulting in serious wear and tear ring gear, bolts are often loosened the main reasons: the site installation space is small, poor assembly, resulting in split ring gear force uneven; overload operation; only installed in the tail of the drip tank on the chain Lubrication, ignoring the active gear ring and chain meshing Department of lubrication; environmental dust, chain adhesion dust and more; ring gear operating temperature is high, so that the tension of the bolt is not enough.It's good for the running of trough belt conveyor. In response to the above situation, we took targeted measures in March 2004: self-mapping, design, production of integral ring gear and prior assembly in the workshop, making a set of active sprocket device and the use of the overall replacement of temporary stop to ensure The ring gear force uniform, so that it meets the assembly requirements; In the active gear ring and chain meshing Department added a lubricating oil pump, according to the operation at regular intervals to start the oil pump will be injected into the ring gear and the gear meshing Department, ensuring that Gear ring and the chain meshing parts of the normal lubrication; the ring gear and the wheel fixed bolts replaced by high strength bolts and heated to 801, make full use of the principle of thermal expansion and contraction, increasing its tension to prevent loosening; in the chain Every 20m made with the old belt slightly smaller than the width of the chain U-shaped clip, fixed in the rack to clean the chain of dust; strengthen kiln system operation, improve clinker cooling effect, and reduce the number of overload equipment.It's good for the running of trough belt conveyor. After the transformation of the trough conveyor put into operation, running well. Now a ring gear life of 1-12 months, completely changed the original life of less than 3 months and frequent parking fastening or replacement of bolts. The main machine, auxiliary motor original copper ring is replaced with the corresponding form factor of the same iron slip ring, making the ring more wear-resistant which can have a longer life. The original high carbon content carbon brush (brush motor model of the host: J201, size 12.5mmx32mmx50mm, deputy motor motor carbon brush model: J201, specifications for lOmmx25mmx50mm) replaced by the same overall dimensions of copper A high amount of carbon brushes (model number: J164) make the carbon brushes more conductive, withstand higher temperatures and are less susceptible to melting at high temperatures. The use of effect rate is greatly reduced, equipment maintenance costs are greatly reduced. It's good for the running of trough belt conveyor. From June 2006 to complete the transformation so far, the host, deputy motor burn table to reduce to less than 1 units / year. In addition, the service life of the motor slip ring has been greatly improved, from the completion of the transformation to the present 6 cranes host, deputy motor slip ring after more than two years of use of its surface with little wear and tear, and still maintain intact. As the original control host, deputy motor start and stop the exchange of AC contactor replaced with solid-state relay, there is no contact contactor burn out the problem, every month for the purchase of contacts completely saved funds.

TXroller specialized in conveyor equipment and conveyor accessories. Decades of experience have given us a strict procedure for quality control. More than 80 percent workers have been working in our factory for over 5 years. Since 2004, Mr.Cui expand the filed of bulk material handling and make the company grow again. Mainly manufacture Conveyor Roller, steel roller, return roller,Conveyor Frame & Station, Pulley, Impact Bar/Bed and other conveyor accessories, such as Rubber Ring, Tube, Shaft, Bearing seat and Seal.The roller is an important part of the belt conveyor, many types, large number. It accounts for 35% of the total cost of a belt conveyor, with more than 70% resistance, so the quality of the roller is particularly important.The role of the roller is to support the conveyor belt and material weight.Today we talk about the trough roller and return roller. Mainly introduce the role of conveyor accessories: 1)Roller stamping bearing: roller bearing is divided into two kinds, one is punching bearing, the other is cast iron bearing. Most of the stamping bearing with steel pipe welding, cast iron bearing housings are used and pipe extrusion. Stamping bearing is characterized by a good seal, the overall strong endurance, cast iron bearing the greatest feature is the high concentricity, but the bearing capacity than the lower bearing. 2)Roller bearings: is one of the most important parts in conveyor accessories, the bearing a direct impact on the life of the roller. So choose roller bearings, roller parts than choose other more cautious. 3)Roller seal: roller sealing material is divided into polyethylene and nylon. Polyethylene low cost, but relatively poor wear resistance, on the contrary, nylon material sealing cost is relatively high, but high wear resistance. 4)Roller shaft: roller shaft is divided into cold drawn steel shaft and ladder shaft. Note: The tolerance of the roller shaft must be guaranteed between plus 0.002mm - 0.019mm. 5)Retainer: idler used in the spring made of spring steel, played a fixed roller string move. Poor poor spring flexibility, variability, under the stamping of the external force can not be a good control of roller string. 6)Retaining ring: the fixed parts of the shaft is divided into axial fixed and circumferential fixed. One of the conveyor accessories, the roller bearing plays an important role in the conveyor and is an important part of the roller. Due to the large number of species, its performance has become the key to ensure the quality of roller. Especially in the roller accessories in the bearing, the life of the roller has a direct correlation, the following reason for its easy to analyze a simple analysis. 1) the bearing material does not meet the standards, easy to use in the process of erosion caused by early scrapped. 2) the installation of bearings is also one of the reasons for the damage, a reasonable installation of the operation and life are related, and the installation of pressure control properly, but also to reduce the bearing wear. 3) the bearing is not cleaned or the equipment does not dry function, the bearing has not been demagnetized, very easy to absorb dust, so very detrimental to its use, because the water and dust easily cause erosion, causing damage.

The belt running deviation is the most common fault in conveyor accessories working. In order to deal with this kind of problems, attention should be paid to the scale precision of the device and the usual protection and maintenance. There are many reasons for the deviation of running, depending on different reasons. 1. Adjust the orientation of the conveyor accessories The belt can adjust the position of the roller to adjust the deviation when running in the middle of the belt conveyor. The hole in both sides of the idler is processed for adjustment. The detailed adjustment method is to specify which side of the belt is inclined, which side of the roller group moves forward in the direction of the belt, or the other side of the belt. The lower part of the roller group should be moved to the left, and the upper part of the idler is moved to the right. 2. The device self-aligning roller group Self-aligning roller group, there are many types such as center, four connecting rod type, vertical shaft type roller and its principle is choose to block or roller direction in the plane of the lateral thrust block or attack to heart to make the belt running deviation of the belt can be adjusted. This method is usually used when the total length of belt conveyor is shorter or the belt conveyor is running in two directions. The reason is that the shorter belt conveyor is simpler to run and not easy to adjust. This method is not the best choice for long belt conveyor, and the application of the conveyor accessories can have a certain effect on the life of the belt. 3. Adjust the driving drum and turn the direction of the roller The adjustment of driving drum and redirection roller is an important part of conveyor accessories. Because a belt conveyor has at least two to five rollers, the device orientation of all the roller must be straight in the center line of the belt conveyor's length direction. If the deflection is too large, it must be deflected. The adjustment method is similar to the adjustment of roller. On the head to the right side of the drum, such as belt running deviation, the bearing should move forward, on the right side of the belt to the drum of the left side of the wandering, is on the left side of the bearing should be moving forward, can also be on the left side of the corresponding bearing seat back or on the right side of bearing seat back. The adjustment of the tail drum is the opposite of the head roller. Repeat until the belt is adjusted to the more ambitious orientation. The position of the best accurate device before adjusting is the drive or redirection of the drum. 4. Adjustment of tension Adjustment belt tension is a very important link of belt conveyors accessories adjustment. The two redirection rollers on the upper part of the heavy hammer should be straight in the direction of the gravity perpendicular to the gravity perpendicular to ensure the horizontal axis of their axis. When using spiral tension or oil cylinder hydraulic tensioning, the two bearing seats of the tensioning roller should be shifted together to ensure that the roller axis and belt longitudinal direction are straight. The adjustment of the detailed belt running deviation is similar to that of the roller. 5. Transfer point blanking position influence on belt running deviation Forward the points of material blanking bearing has very big effect on the belt running deviation, especially in the two belt machine in the horizontal plane projection into straight influence is greater. The relative height of the two belt machines at the forwarding point should normally be considered. The lower the relative height, the higher the weight of the material, the greater the lateral impact of the belt on the base belt, and the material can hardly be centered. The bias of the material on the cross section of the belt causes the belt to run sideways. If the material goes to the right, the belt runs sideways to the left, and vice versa. The relative height of two belt machines should be increased in the planning process. It should be considered carefully in the ways and dimensions of the funnel, guide slot and so on. Generally, the width of the guide slot shall be the two thirds of the belt width. To reduce or prevent the belt running to increase the baffle material, change the conveyor accessories and direction of the material. 6. Two-way adjustment of deviation of belt conveyor running operation Two-way operation of belt conveyor belt running deviation adjustment than one-way belt conveyor running wide more difficult to relatively detailed adjustment should be first in one direction, and then adjust the other direction. When adjusting, you should carefully observe the link between the direction of belt movement and the tendency of running deviation, and make adjustments one by one. The main points should be in the driving drum and the adjustment of the drum, followed by the adjustment of the rollers and the adjustment of the feeding point of the material. Together, it should be noted that the belt should be evenly distributed in the direction of the length of the belt in the direction of vulcanization joint, and the force on both sides of the guide chain will be equal to the same.

Those are nothing but rollers, which support to conveyor belt and those can rotate in any direction. The idlers are also divided into various types depending upon their requirement. A troughing idler is comprised of a central idler roll, which has a fixed width, and two or more wing idlers located on each side of the central idler roll. The wing idlers can be adjusted up or down to change the toughing angle, which affects the depth of the trough created by the conveyor belt as it moves.Troughing idlers/troughing rollers found on the carrying-side, along the length of the conveyor.Unlike the centre, horizontal roll, the wing idlers are cranked up to an angle known as the troughing angle. This troughing angle ensures that the carrying belt maintains the same cross-sectional area troughout the carrying strand, so that the load-bearing capacity of a particular conveyor belt is the same along the conveyors' full length, Troughing idlers can comprise 3-roll or 5-roll idler sets. The 5-roll idler configuration offers a more uniform cross-section which results in a greater net carrying capacity for the same belt width and belt speed. It has been stated above that there are basically two types of idlers namely, carrying and return idlers, The troughing angle adopted are: 15°, 20° , 25° , 30° , 35° , 40° , 45° . ... It is important that the belt trough properly. They are effective for supporting conveyed materials between drive rollers and are the sole roller type in gravity conveyors. These components support conveyor belts and control the flow of materials.

The Rollers are designed to rotate in one direction only preventing a fully loaded snapped, Conveyor Belt from running back into the Tail Pulley – the Conveyor Belt is immediately arrested. Why an Idler Brake? 1) To stop runaway conveyors, which cause: Damage to infrastructure. Danger of injury and death to personnel in the vicinity. The necessity of lengthy and difficult cleanup operations. The loss of production due to standing time, with the associated cost (loss of income). 2) To simplify the construction and maintenance of conveyors: Pulling in of belts is now easily accomplished. The belt may be let loose at any stage and at any position on the incline - and will simply remain there. Broken belts, with or without load, will remain in position, allowing them to be spliced and repaired at leisure. 3) To provide an alternative to expensive backstops, Which are ineffective when the belt snaps before the backstop, as well as to other systems for catching runaway conveyors, which are only partly effective, normally only attempting to catch the belt once it has gained some momentum, and even then catches the belt in only one or a couple of locations, giving rise to extreme tensions and forces in the belt.

Frame or Galvanized frames is to provide for a minimum gap between the rolls and additional protection to the conveyor belt. Frame or Galvanized frame outer slopers are designed to prevent material build around the shell end causing premature wear to avoid shell by jamming role. Base frame cross members for optimum power to weight ratio, while designed to provide adequate support to the role under load conditions. All frames are inspected to confirm the accuracy of the main dimensions before the start of the weld run. Selected images will be removed subject of the productions at intervals and the full dimension checks and welding quality control.

With the increase of the conveyor speed and the increase of the distance, the safety and reliability of the belt conveyor is also increasing. The normal operation of the belt conveyor depends on the quality of the main parts, and the safety protection device is also a link that can not be ignored. It can reduce the damage degree of accidents to people and equipment.Conveyor idler rollers play a vital role for belt conveyor safety operation. Mainly used in the design of coal handling system in thermal power plant of belt conveyor safety protection device: two level deviation switch, two-way pull switch, longitudinal tear protection device, slip detection speed display device, chute protection device, material flow detector, a detector etc.. It is an important guarantee for the safe operation of coal transportation system to choose the type and layout of the protection device reasonably. In the running process of the two level deviation switch belt conveyor, the conveyor belt often runs off. In order to prevent this phenomenon, the idler roller is often used on the conveyor's upper roller, and a group of idlers are arranged on every 10 groups along the length of the belt conveyor. Although these anti deflection measures play a partial role in a certain extent, they can't completely eliminate the deviation phenomenon. It sends out signals by detecting the running deviation of belt conveyer belt, and realizes the automatic alarm and stop function of the belt conveyor.Conveyor idler rollers play a vital role for belt conveyor safety operation. Two level deviation switch arranged in pairs of belt conveyor middle frame, each 100m belt conveyor of C three recommended installation deviation switch if the new input belt conveyor in the unused before installation deviation switch, then the deviation alarm error, if used in a period of time, the most easy to master belt conveyor the deviation of position, and then targeted the installation, will have the best effect. The deviation switch should be installed on the inclined angle of the belt conveyor to ensure that the touch roller and the edge of the belt are vertical.Because the belt conveyor has different degrees of natural deviation which does not affect the normal work, so when installing, we should also pay attention to the distance between the roller and the edge of the belt, which is 40 ~100mm away. The two-way rope pulling switch is mainly used for timely handling and preventing accidents of personal equipment when transporting materials. The rotary cam structure is adopted mostly, and the swing rod can be rotated. When an emergency occurs, a pull - off switch is pulled at any place along the site, and a stop signal can be sent. Conveyor idler rollers play a vital role for belt conveyor safety operation. There are two kinds of two - way pull - rope switch automatic reset and manual reset. When the switch sends out the stop signal, the swing lever is automatically restored to the position before the action. After the failure is eliminated, it can run the normal operation immediately.

Belt conveyors can be added to the conveyor belt in various forms, such as belt conveyors, flat belt conveyors, climbing belt conveyors, roll belt conveyors, turning belt conveyors,Side gears, etc.Good quality conveyor roller is a very important part for belt conveyor.Accessories such as plates and skirts can meet a variety of process requirements. Belt conveyors have different characteristics and forms.The belt conveyor should be kept clean during use and storage, avoiding direct sunlight or rain and snow soaking to prevent contact with acids, alkalis, oils, organic solvents, etc., and one meter away from the heating device.The storage temperature of the belt conveyor should be maintained between 18-40 ℃ and the relative humidity should be between 50-80℃. The conveyor belt should be placed in the reel during storage and must not be folded. Each season should be transferred once during the resettlement period. Different types and sizes of conveyor belts are not suitable for use together, and the joints are preferably glued.Good quality conveyor roller is a very important part for belt conveyor. The belt conveyor should select the type, structure, specifications and number of layers of the conveyor belt according to the conditions of use. Conveyor speed should generally not exceed 2.5 m/s. Materials with bulk size, high wear resistance and fixed discharge devices should be used at low speeds. The relationship between the diameter of the conveyor roller of the belt conveyor and the belt layer of the conveyor belt, the matching of the transmission drum, the groove angle of the reversing drum and the drum should be reasonably selected according to the design specifications of the conveyor. The feed direction should be in the direction of travel of the conveyor. In order to reduce the impact on the conveyor belt when the material falls, a chute should be used to reduce the material falling distance. The belt receiving portion should shorten the idler spacing and use a buffer roller as the leaking material. Good quality conveyor roller is a very important part for belt conveyor.The belt conforms to a soft and moderate baffle to prevent the baffle from being too hard and scratching the belt surface of the belt. The high temperature resistant steel belt conveyor belt is made of steel wire transversely and horizontally. The surface of the steel mesh is galvanized or copper plated. The lower surface of the stencil is covered with a rubber layer. During the transportation of high temperature materials, the entire surface is not delaminated and the performance is better than delamination. Heat resistant conveyor belts are more reliable.

Belt conveyor is the main tool to transport coal, its damage and repair will affect the production of coal, making the whole production line in a stagnant state. The protection and control of the belt conveyor is an important part in the process of coal production, the market also has a lot of protection device of the belt conveyor, the main is to detect the belt conveyor, when there is deviation, tension, temperature, smoke, tear and speed of failure for voice alarm. In this paper, after a large number of investigation and research, the improvement of the belt conveyor protection and control design is put forward.The protection device of the belt conveyor mainly realizes eight major protections, such as deviation, tension, temperature, smoke, coal position, tear, speed and emergency stop. When a fault occurs, the protection device will give voice alarm and display alarm according to the fault.It's very important for ISO conveyor rollers. The speed protection and control of the belt conveyor's direct start makes the tension of the conveyor belt increase by several times, which has a great impact on the components of the conveyor, and affects the stability and service life of the components, conveyor belts and the whole machine. Although the price of the soft starter is lower than that of the frequency converter, because the design device will have speed control when the conveyor works normally, the control device of the soft start uses the speed control device of the transducer. When the control system starts or stops, the frequency converter starts to work. The frequency converter can automatically track the motor's frequency, voltage and phase, and achieve the same frequency, the same voltage and the same phase switching. The switching process is very stable, so the current will not change much.The speed of protection and control in addition to start and stop state, the speed of the conveyor belt in the 10s (50%c~70%c) when the rated speed, rated speed or speed to be 50%, or 110% of the rated speed with speed, speed control device should work to achieve the frequency control. After a certain period of time, if the speed is still overrun, in Zhidai conveyor operation.When the two way emergency switch is applied to 40~ 120N force on any side of the drawing line, the inverter controls the operation of the belt conveyor, so that the belt conveyor can be stably terminating, and it can be self locked and reset.It's very important for ISO conveyor rollers. When running deviation, the control system starts the rectifying device in time, and the alarm light is lit at the same time. When the deflection angle of the probe bar of the deviation sensor reaches the set value, the voice alarm is started and the belt conveyor is forced to stop. When the belt conveyor stops running, the rectifying device can be started manually.Tension protection and control. When the tension sensor detection device detects the loosening of the conveyor belt, the alarm lamp is bright, so that the tension device tightens the conveyor belt. Conversely, when the conveyor belt is too tight, the tension device looses the conveyor belt, so as to effectively control the tension degree of the belt conveyor. When the belt tensioning degree exceeds the limit, start the voice alarm, and in Zhidai conveyor operation.Temperature, smoke protection and control, when the temperature of the temperature sensor of the temperature sensor exceeds the set value, the alarm light is bright, and the water spray is cooled at the same time. When the temperature is still high for more than a certain time, the voice alarm is started and the belt conveyor is stopped. Smoke protection and control of continuous 2S, when the smoke is monitored environment coal concentration exceeds the speed detection device detecting speed detection device control device of emergency stop control device of liquid crystal display keyboard input to microcontroller settings, alarm lights, and reduce the smoke density of water. When the smoke concentration is still high for more than a certain time, the voice alarm is started and the belt conveyor is stopped.It's very important for ISO conveyor rollers. The working environment of the belt conveyor is generally bad. Therefore, during the operation of the belt conveyor, it is necessary to detect the performance and protective parameters of the belt conveyor in time, so as to ensure the safe, efficient and stable operation of the belt conveyor. The protection and control of the belt conveyor in time can greatly reduce the cost and improve the production efficiency.

The tail of the retractable belt conveyor is suitable for the convergence of the retractable belt conveyor and the retractable belt conveyor in the transportation lane of the coal face and has the advantages that the scraper transfer machine and the tail end of the self- Retractable belt conveyor at the tail of the conveyor belt deflection, scraper transfer machine head height adjustment and other functions to ensure that the cis-slot transport reprint unobstructed to meet the high-yielding high-efficiency face, advanced support requirements are fast Today's coal long wall face to achieve high yield and efficiency of the preferred equipment. In the process of self-moving tail sliding forward, due to uneven resistance, often appear tail shift tail transfer, resulting in tape deviation, and then the phenomenon of coal leakage. Therefore, the shift tail should be a function of lateral shift, in order to improve the flexibility and reliability of the shift, the use of hydraulic cylinder side shift type. Since the end of the tail rotor to sled orbit, by adjusting the cylinder side of the hydraulic cylinder and the coordination of telescopic, to move the tail of the move to achieve lateral movement to achieve the purpose of adjusting. In order to reduce the bore diameter, two side shift hydraulic cylinders are respectively installed between the skid and the skid shoe at the tail end of the tail end of the transfer machine. According to the arrangement of the equipment along the trough, the minimum width of the tail end and the required lateral displacement To determine the side shift cylinder stroke and lateral displacement of respectively 200mm and 245kN 1.3 Sliding Car Structure Design Sliding trolley is one of the important working parts of the self-tailing tail, its role is to support the scraper transfer machine head And its bridging section, so that it can move back and forth on the main rack track, while accepting the coal from the loader, but also the fulcrum from the end of the shift tail, therefore, need to optimize the structure and the rational use of materials to improve the car The strength of the key parts and the overall stiffness. It is mainly composed of frame, front wheel, hinged frame, rewinding drum and redirecting drum and other parts, the structure as shown. Retrofit drum mounted on the car, reducing the length of the machine, which can shorten the length of the supporting scraper plate rack section, to improve the self-moving tail of the force situation. In order to improve the force of sliding trolley, the four wheels of the trolley need to keep good contact with the rail while the main rack rail deflects, so the connection between the rear axle and the frame is designed as a pivot hinge.

Application Advise Tape Conveyor is the best equipment for continuous transportation and reprinting of bulk materials. It is widely used in various fields. In the case of coal mines, the first choice of belt conveyor for the main shaft of mine shaft is the first choice of modern mine shaft. However, the tapes bearing the material have been broken by belt in high-speed and high-tension working conditions, especially in the case of broken shaft incline. It is huge. First, the damage caused by the transport equipment itself can range from a few million. Secondly, it is more difficult to handle the accident to resume production. It is extremely difficult to clean hundreds of tons of coal and kilometers of tape at the bottom of the inclined shaft. The loss of production is huge, amazing. Broken belt to prevent and reduce losses is a problem that must be solved, the implementation of break protection is included in the safety regulations. However, it is very difficult for a large-size belt conveyor to carry out the reliable technology of belt breaking protection. Therefore, it is necessary to continuously carry out the technical research on the belt breaking protection, and to discuss the implementation technology, the mode and the effect of the belt breaking protection of the large-size belt conveyor. The advantage of broken belt arrest is that the facilities are simple and the reliability is high. The disadvantage is that the tape length is long, the arresting point is large, and the daily maintenance workload is heavy, the maintenance can not keep up the reliability and will be discounted. Therefore, all kinds of ways are constantly exploring and improving. Monitoring techniques and methods In order to improve the transport capacity of the belt conveyor, a pressed steel cord core technology is used on the tape, so monitoring the damage of the steel cord core can predict the possibility of tape breakage. Foreign use of magnetic induction principle to detect the steel cord core, developed a * CBM detector. "The detector is by the upper and lower sensors on the middle of the steel cord detection, the detection signal processing, display, we can know the steel cord core Damage situation.In recent years, the domestic electromagnetic induction type steel cord in-line testing technology research and application Discussion and Suggestion on Broken Belt Protection There are some shortcomings in the application of broken belt protection in the field at present in China. The main defects are as follows: the disadvantage of the magnetic induction detection method is that the detection output is in the form of relative data value, Fault accuracy is more difficult. In particular, the professional qualifications of judges are required to be high, and there are fewer on-site personnel in the field. At the same time, the amount of data to be inspected is also large and the labor intensity is high. It is recommended to develop software with identification ability and form the auto-prompt or report button (down to page 80). Since the main, backup, backup 3 and main 4 4 contacts are normally open, the two relay magnetic lines in the switching device Circle owners and t are no electricity, 2 fans are in power outage locked state. Stop wind and protect themselves safely: When both fans are stopped due to power failure, once the power supply is restored, neither of the 2 turbines will start its own operation, so as to avoid self-blowing when the gas exceeds the limit and is not treated. A wind blow "security risks.

ith the increase of the conveyor volume and the increase of the distance and speed of the single conveyor, the safety and reliability of the belt conveyor is also increasing. The normal operation of the belt conveyor depends on the quality of the main parts, and the safety protection device is also a link that can not be ignored. It can reduce the damage degree of accidents to people and equipment.Mainly used in the design of coal handling system in thermal power plant of belt conveyor safety protection device: two level deviation switch, two-way pull switch, longitudinal tear protection device, slip detection speed display device, chute protection device, material flow detector, a detector etc.. It is an important guarantee for the safe operation of coal transportation system to choose the type and layout of the protection device reasonably.Good quality conveyor rollers play a vital role. In the running process of the two level deviation switch belt conveyor, the conveyor belt often runs off. In order to prevent this phenomenon, the idler roller is often used on the conveyor's upper roller, and a group of idlers are arranged on every 10 groups along the length of the belt conveyor. Although these anti deflection measures play a partial role in a certain extent, they can't completely eliminate the deviation phenomenon. In order to make the belt conveyor cause no accident due to deviation, a two grade running off switch is usually needed, usually with a double convex wheel structure, with vertical roller automatic reset function. It sends out signals by detecting the running deviation of belt conveyer belt, and realizes the automatic alarm and stop function of the belt conveyor.Two level deviation switch arranged in pairs of belt conveyor middle frame, each 100m belt conveyor of C three recommended installation deviation switch if the new input belt conveyor in the unused before installation deviation switch, then the deviation alarm error, if used in a period of time, the most easy to master belt conveyor the deviation of position, and then targeted the installation, will have the best effect. The deviation switch should be installed on the inclined angle of the belt conveyor to ensure that the touch roller and the edge of the belt are vertical.Because the belt conveyor has different degrees of natural deviation which does not affect the normal work, so when installing, we should also pay attention to the distance between the roller and the edge of the belt, which is 40 ~100mm away.Good quality conveyor rollers play a vital role. The two-way rope pulling switch is mainly used for timely handling and preventing accidents of personal equipment when transporting materials. The rotary cam structure is adopted mostly, and the swing rod can be rotated. When an emergency occurs, a pull - off switch is pulled at any place along the site, and a stop signal can be sent. There are two kinds of two - way pull - rope switch automatic reset and manual reset. When the switch sends out the stop signal, the swing lever is automatically restored to the position before the action. After the failure is eliminated, it can run the normal operation immediately. The manual reset type, when the switch sends a stop signal after the switch, automatic locking, and the warning signs show this switch is in working condition, can make the site management to accurately identify different installation position of the switch is action, convenient on-site management personnel to timely treatment, accident treatment, restore to the original state of manual switch. The two-way pull - rope switch is installed along the middle frame of the belt conveyor, arranged on one side or both sides of the belt conveyor by the running channel. The distance between two pull - rope switches is suitable for 50~80m. When wire rope is used as the drawstring, the spacing between the fixed cables and the pullout rings should be less than 3m, so as to avoid the rope's vertical winding. When the nylon rope is used to pull the rope, the spacing between the fixed cables and the pullout rings should be limited to 4~5m. In the installation, we should also pay attention to the installation of a fixed direction pull ring on the left and right side of the rope switch.Good quality conveyor rollers play a vital role. When the longitudinal tearing monitor belt conveyor is running at high speed, the material falls along the chute to the conveyor belt surface. If there is a metal piece or a large material in the material, it is possible to break the conveyor belt through the tape and cause the belt to tear along the longitudinal direction. The longitudinal tearing of the conveyer belt is a malignant accident. In order to avoid the longitudinal tear of the conveyer belt, the longitudinal tear monitor should be installed on the belt conveyor in the design. It can continuously survey the belt conveyor running. When the longitudinal tearing failure occurs, the stop signal is sent out in time to prevent the failure from expanding. The longitudinal tear monitor consists of two parts of the perceptron and the control box.

According to the preparation degree of mining, the ore reserves can be divided into three levels, namely, exploiting reserves, mining reserves and reserve reserves. These three reserves are called tertiary reserves. (1) Exploiting reserves Through the tunneling and opening of the roadway, a certain transportation, ventilation and drainage system has been formed. The deposits in the mine control area are called exploiting minerals, as shown in the fourth stage. (2) Acquisition of reserves It is part of the exploitation of minerals. Where the mining area or the mining wall completes the mining quantity specified in the mining method, the reserves in these mining areas or mine walls are called mining reserves. (3) Reserves It is part of the acquisition reserve. The reserves of the cutting engineering quantity specified in the mining method in the mining area or the mining wall are called reserve reserves. As shown in Figure 3-1-8, the first stage and the second part of the second stage have completed the cutting work, which is the reserve. In the three steps of mining the above-mentioned deposits, in the initial stage of mining, each mining step is carried out in sequence, that is, the required three-level reserves can be put into production according to the infrastructure construction schedule; in the normal production period (that is, after the production is completed), the implementation should be implemented. The principle of "excavating and cultivating first." It is generally necessary to ensure the indicators specified by the third-level reserves, otherwise mining imbalances will occur, causing mine production to be chaotic and passive. Therefore, we must always pay attention to properly arrange the development, mining, and recovery work. It is necessary to follow the principle of pioneering the advance and adopting the advanced mining. Only in this way can the production of the mine be sustained, stable and balanced. This is because development, mining and cutting reflect the degree of readiness for mining. The advanced relationship between the above three steps, the degree of preparation is usually expressed by the mining time required for the three-level ore provided by the tunneling, mining, and mining roadway. In general, mines should have more than three years of mining capacity, about one year of mining and mining, and about six months of reserve.

Deviation conveyor belt conveyor is the most common faults, its timely and accurate processing is to protect its security and stability operation. Many phenomena and causes of deviation, to take a different method of adjusting deviation phenomenon and according to different reasons, in order to effectively solve the problem. Analysis and explanation of such failure causes and treatment methods: (1) driving the drum head or tail bend pulley axis is not perpendicular to the centerline of the conveyor, resulting in the deviation conveyor bend pulley at the head or tail drum, the drum deviation on either side of the belt tension in the drum degree of inconsistency, along the width direction of the traction force Fq also inconsistent suffered, to increment or decrement the trend which would make a decrement additional conveyor belt moving direction of the force, leading to the loose side of the belt deviation, the so-called "run loose do not run tight ", the adjustment method for the head pulley conveyor belt deviation to the right side of the drum, the bearing seat on the right side should be moved forward, the belt deviation to the left side of the drum, the left bearing seat should be moved forward, corresponding to the left can also be moved after the bearing or bearing on the right shift. Rear roller adjustment method and the head drum opposite. After repeated adjustment until the belt tuned ideal position adjustment before driving or redirecting roller Simply the best install its exact location. (2) Simple roller outer surface machining error, sticky material or wear caused by uneven diameter sizes, the belt deviation to be larger diameter side. In this case the solution is to clean the surface of the drum stick materials, processing errors and uneven wear to be replaced down reprocessed plastic bag handling. (3) reproduced point blanking malposition, blanking position has a very big impact on the conveyor belt deviation, especially on the bar conveyor and the conveyor section in the horizontal plane of projection perpendicular to a greater impact. Gao generally should consider the relative degree reprint point up and down two belt machine. The relative height of the lower horizontal velocity component material larger side of the lower belt of the greater impact, but the material is difficult to center. So that the cross section of material on the belt skew, if the material is biased to the right side of the belt deviation to the left, and vice versa. For deviation in this case, in the design process should increase the relative height of two conveyors as possible. In the space constraints of the vertical belt conveyor hopper, chutes and other parts of the form and size should seriously consider. General guide chute width should be about three-fifths of the width of the belt is more appropriate. To reduce or avoid the belt deviation can be a barrier to increase in the striker plate material, changing the orientation and position of the whereabouts of the material.

1.The drive impact roller is driven by the motor through the gear unit,the conveyor belt relies on the friction between the drive roller and the conveyor belt to drag the scaffolding on the ramp and the road.To have reliable anti-slip measures, in addition to timely cleaning frost, but also can be used to lay ash, sawdust, sand and other methods for non-slip. 2.All technical requirements must follow the manual,the role of the carrier roller conveyor belt is to support the conveyor belt and material weight,Reduce the friction of the conveyor belt with the roller.Which plays a key role in the life of conveyor belts above 25% of the total cost of the conveyor. There are five criteria for judging the quality of the roller:Roller dustproof performance,Roller waterproof performance,Roller axial bearing performance,Roller impact resistance,The roller is an important part of the belt conveyor, many types, large number. The heat-resistant conveyor belt is mainly based on the resistance of the tropical belt to the loss of the main performance and the different heat-resistant level for the conveyor belt reform.Environmental protection has become the focus,Protect the environment, save raw materials.Is such a simple simple products, many domestic and foreign related professional research institutes and engaged in the production of engineering and technical personnel, is committed to the research on the roller to improve,There are hundreds of patent applications, there is no problem to solve the vulnerability of the roller. Most of the conveyor belt, conveyor roller use of the environment there are water pollution and dust, the material will be on the roller body wear or corrosion.Dust and dust into the labyrinth seal is a physics principle that has not been found by people. As we all know, the labyrinth seal gap is big, the sealing effect is not good, is correct. However, that the labyrinth seal gap is small, the number of layers, the sealing effect will be a good understanding, but it is a big mistake. The second core technology is the manufacturing accuracy of the roller. Structure chain plate feeder from the silo interface, guide trough, manual gate device, drive sprocket group, wheel group, chassis and other components,the components are bolted, handled and assembled, and can be divided and integral.Ground or downhole are applicable to the grooved roller coal mine shaft roller damage caused by the following main reasons.Leaching and slime on the roller bearing pollution, resulting in bearing resistance increased until the stuck failure;Aligning the bracket to install the friction-aligning roller, and the tape is not 90 degrees vertical, but the use of lateral friction force to prevent tape deviation.The roller wall will wear and tear quickly, while the tape wear is also very serious, we can see the conveyor belt roller on the conveyor life plays a key role.

What to Consider Before Purchasing a Rubber Belt Conveyor? Doing the research for a new belt conveyor system can be a daunting task: Should you stick with a traditional fixed system or is it time to upgrade to a modular conveyor system? The following checklist can help you determine what type of belt conveyor system is most suitable for your parts conveying applications: Portability Determine whether or not the conveyor will be needed for more than one process or at more than one location. Fixed metal conveyors are heavy and not easily moved. Plastic modular conveyors are lightweight and can be rolled from one plant to another or from one line to another. If you require quick access to machinery for servicing or changeovers, modular conveyors can be easily moved out of the way. Ease of Belt Conveyor Repair Mishaps can shut down a production line for a long period of time. Damaged conveyors, belts and accessories can be time-consuming to replace. Look for conveyor systems that can be repaired quickly and easily without specialized labor. Also consider conveyor belt design. If belts constructed of interlocking links are damaged, the damaged sections can be replaced within hours instead of days or weeks. Access to Replacement Parts Timely access to replacement parts is crucial for production uptime. Choose a supplier that has replacement units and components on hand and can deliver them within a few days or overnight if needed. Or choose a belt conveyor system that allows you to stock standardized replacement modules or accessories. Flexibility If you need to retool a production line quickly to meet deadlines, make sure that your belt conveyor system can be easily reconfigured. A modular system with standardized modules in a range of sizes and shapes provides agility. Using conveyor modules to customize conveyor lines may also enable users to fine-tune product lines to fit confined cell spaces. Ease of Maintenance Maintenance and uptime can affect productivity. Determine what type of maintenance your new system will need. Consider a self-lubricating system. Belting on traditional conveyors, such as PVC belting, requires frequent alignment and can be difficult and time-consuming to install and service. Configuration Options Conveyor systems should go wherever you need them to go. Make sure your new belt conveyor system includes configuration options like turns and inclines/declines. Modular systems should offer an array of accessories and specialized application modules that integrate with other modules to provide configuration latitude, dependable performance, and cost savings.
