Scientific and reasonable treatment of belt deviation can effectively ensure the normal operation of production system. In order to deal with the belt deviation, the position of the driving roller and reversing roller of the conveyor should be adjusted first, and different treatment methods should be adopted according to different running directions. The specific performance is: adjust the position of the driving drum. If the head drum is to the right, the right bearing seat needs to move forward; The tension of the belt conveyor is an effective device to ensure that the belt always has sufficient tension; Adjust the belt diameter.

Belt Conveyor Roller Introduction What is a belt conveyor roller?Conveyor rollers are parts of a conveyor belt which is used to move products or loose bulk goods such as coal, sand or iron ore. The conveyor rollers are part of this installation and are essential to enable transport.The conveyor belt is the carrier of the materials and passes around the pulleys and rollers as a loop. The conveyor pulleys drive the belt, tension it and guide it in the required direction.  The conveyor rollers carry the conveyor belt from drum to drum. They serve purely to support the belt.How does a conveyor roller work?Conveyor rollers are therefore an essential part of the conveyor belt. How does a conveyor roller work? As described above, the conveyor roller is responsible for supporting the conveyor belt. Because the conveyor belt revolves around the pulleysas an endless loop, the conveyor belt has an outward section and a return section.

Belt conveyor PrinciplePrinciple of operation:A belt conveyor is simply an endless strap of flexible material stretched between two drums and supported at intervals on idler rollers. When the drum rotated by the driving motor, the belt will move with roller due to frictional resistance, there by the material placed on the belt will be transported from one place to other.Majority of belt conveyors are equipped with flat belts. Troughing the belt or fitting sidewalls will increase the carrying capacity. Fitting the transverse slats or texturing the surface of the belt will help to operate the belt conveyor for steep inclined application. The end of the conveyor where transported material is loaded is termed as ‘tail end’ or ‘feed end’ and the other end, from which the load is discharged, is called as ‘head end’.Belts: Belts may be flat or fitted with a pattern of cleats or flights molded into its surface to reduce the tendency for the conveyed material to slip. The belts may be constructed with vertical sidewalls, which may be supported by transverse slats to operate much steeper incline than the normally accepted. Two methods are employed i.e. vulcanized splice and mechanical fasteners at the ends of the belt to make the belt endless. The expensive vulcanized splice gives a much stronger and longer lasting joint. The cheaper mechanical fasteners tend to restrict the working conditions of the belt.Idlers: The carrying capacity of the flat belt is increased by modifying the cross sectional profile of belt so that it forms a trough. This is achieved by troughing idler, which consists two to five rollers.Drive arrangements: The drive may be at either end of the conveyor, but prefers to drive the head end drum since the smallest amount of belt being subjected to the maximum tension. The effectiveness of the conveyor drive is dependent upon the difference in tension between the ‘tight side’ and the ‘slack side’ of the belt, the friction between the belt and the drive drum and the angle of wrap or arc of contact of the belt to drum. The power that can be transmitted from the driving drum to the belt is limited by the point at which the belt begins to slip. In order to increase the power either coefficient of friction to be increased by applying a rubber lagging to the surface of the drum or to increase the angle of wrap by ‘snubbing’ the drum or by providing a multiple drive.Belt slip: In the belt drive there will inevitably be a certain amount of belt ‘creep’ resulting from the varying tension in the belt as it passes around the drum. The term ‘creep’ refers to the relative movement between the belt and the surface of the drum that happens as the stretch in the belt decreases with the reduction in tension. The arc of the drum surface over which creep occurs will tend to increase as the tight side tension increases, for example as a result of increasing the load on the belt, and if the ‘angle of creep’ approaches the ‘angle of wrap’ the belt will be on the point of slipping. For this reason that a certain inherent tension should be maintained, even in the slack side of the belt.Belt tensioning: The needed tension can be provided in a number of ways by suitable arrangement like pulling back the tail drum or idler pulley and also by providing ‘drop-weight’ or ‘gravity take-up’ device. Hydraulically or electrically powered automatic take-ups are also available which relay on a load-sensitive device to move the tensioning pulley in response to change in operating conditions of the belt.Belt cleaners: When transporting bulk materials that have the tendency to stick to the surface of the belt, the belt conveyors will be equipped with some kind of cleaning technique at the head end to minimize the build-up of material on snub pulleys and return idlers. Theses cleaning methods are such as rotary brushes or scrapper blades of steel or rubber, which may be spring loaded or counterweighted to bear against the surface of the belt.

4 Ways to Reduce Conveyor Belt DamageConveyor belts are both the most important and most expensive conveyor component. To help you reduce damage to your conveyor belt and the potential costly exercise of a belt replacement, we discuss below four ways to reduce belt damage.1. Appropriate Belt Type ​​The type of material and the environment of your conveying will greatly affect the service life of your conveyor belt as the specification of belt will wear more quickly if it isn’t suited to the application.  There are multiple grades of rubber conveyor belting, each of which have special properties that ensure their suitability.For example,If your conveyor requires the use of Grade A, but you instead installed a general-purpose N grade rubber belt you would find that the N grade belt would be more susceptible to wear from the abrasive material. Thus, the service life would be reduced and the belt will require replacement sooner than a Grade A belt.2. Cleaning & MaintenanceTo reduce carryback and the associated wear on the conveyor belt, it’s important to keep the belt as clean as possible during operation. Cleaning of the belt can be effectively achieved with the appropriate belt scraper, v-plows, spray bars and brush cleaners.3. Impact ProductionWhen large and heavy material impacts the conveyor belt, especially at the impact zones, damage can occur to the belt. Impact damage can include tears in the belt or, if the velocity of the impacting material is high enough, the objects can puncture holes in the belt.3.Prevention of Mis-trackingThe conveyor belt can be prone to mis-tracking for various reasons, examples include worn conveyor pulley and material build up. When the belt mis-tracks, it is prone to damage and additional wear, especially along the edge of the belt where unwanted contact with surrounding structure may occur.

In mineral processing production, the transportation of mining equipment is an important problem. There are many kinds of transportation forms of mining equipment, such as automobile transportation, railway transportation, cableway transportation, belt conveyor transportation and so on. Among them, belt conveyor transportation is a common form of transportation.Belt conveyor is divided into two types: ordinary type and special type. Special type can be divided into steel core belt conveyor, steel rope traction belt conveyor, rubber wheel drive belt conveyor, linear friction drive belt conveyor and displacement belt conveyor.Belt conveyor realizes the continuity of transportation process. It has the advantages of large conveying capacity, strong climbing performance, simple operation, safe and reliable, high degree of automation, easy maintenance and repair of equipment. Compared with automobile and railway transportation, it can shorten the transportation distance, reduce the cost and reduce energy consumption. In the mines with large mining depth, long transportation distance and large ore and rock transportation volume, high-strength belt conveyor is an ideal means of transportation.Belt conveyor and automobile or railway transportation, generally through the crushing transfer station, form a combined transportation system, to transport ore (rock) from stope to concentrator, stope to dump and so on. Crushing transfer station can be divided into three types: fixed, semi fixed and mobile. It is generally composed of ore bin, feeding, crushing and discharging devices. The technological process of combined transportation is to transport the ore (rock) from the stope to the crushing bin by car or railway, discharge the qualified block size by the crusher, and transport it to the concentrator and dump by belt conveyor.According to the nature of the conveying materials and local climate conditions, the belt conveyor shall be of open, semi open, fully closed type or only capped on the driving station. But it is necessary to ensure the normal operation of belt conveyor and the requirements of material transportation.

Pipe belt conveyor is suitable for conveying various bulk materials with density of 0 ~ 250kg / m3 under various complex terrain conditions. It is widely used in the material conveying system of electric power, building materials, chemical industry, mining, metallurgy and other industries. The main performance characteristics of tubular belt conveyor are as follows.1.Airtight conveying of materialsThe material is completely enclosed in the tubular belt, and the return belt is turned 180 degrees, so the material will not be scattered and flying, and will not be affected by the external environment. In this way, not only the external environment pollution caused by the scattering of materials is avoided, but also the external environment pollution to materials is avoided. It can also be used in places requiring thermal insulation.2.The conveyor can be arranged along the space curveThe tubular belt conveyor has the ability of small radius bending, which can realize three-dimensional spiral bending arrangement. The conveyor does not need to set up transfer point, and also saves the required additional drum, hopper, dust removal equipment, transfer station civil engineering foundation and power distribution, so as to save the cost of transfer station and multi drive, reduce the failure point and material loss, and avoid the maintenance problem of transfer point.3.Large angle conveying capacityThe friction coefficient between material and belt is much larger than that of ordinary belt conveyor, which can realize large angle transportation, reduce conveying length, save space position and reduce equipment cost. The larger the inclination angle, the shorter the conveyor length, the more economical.4.The width of the middle conveying section is smallThe frame of tubular belt conveyor is only 1 / 2 of the width of belt. In the case of the same conveying capacity, the cross-section width of the round pipe part of the conveyor is only about 1 / 2 of that of the ordinary conveyor. In the case of long-distance transportation, it can greatly save the area and space, and reduce the cost of the trestle.

Because the belt conveyor has the advantages of long conveying distance, large traffic volume, continuous conveying, large conveying capacity, simple structure, convenient maintenance, low cost and strong versatility, it has been widely used in mine production.Characteristics of belt conveyorBelt conveyor is an ideal transportation equipment in coal mine. Compared with other transportation equipment, it has the advantages of long transportation distance, large capacity, continuous transportation, reliable operation, easy to realize automation and centralized control. Especially for high-capacity mines, belt conveyor has become the key equipment of mechatronics technology and equipment in coal mining. Its main feature is that the fuselage can be easily retracted and retracted, with a belt storage bin, the tail can be extended or shortened with the advance of the coal mining face, and the structure is compact. It can be directly laid on the roadway floor without foundation, and the rack is light and convenient for disassembly and assembly. When the conveying capacity and distance are large, the intermediate driving device can be equipped to meet the requirements. According to the requirements of the conveying process, the material can be transported by a single machine, or by a combined horizontal or inclined conveying system for many times. According to the requirements of the technological process, the belt conveyor can receive materials from one or more points flexibly, and also incline to multiple points or several sections.Structures of belt conveyorThe universal belt conveyor is composed of conveyor belt, idler, roller and drive, brake, tension, change direction, loading, unloading, cleaning and other devices. Belt width is the main technical parameter of belt conveyor. Idler is divided into single roller, double roller and multi roller, including trough roller, flat roller, centering roller and buffer roller. The trough roller supports the load branch, which is used to transport the granular materials; The self-aligning idler is used to adjust the transverse position of the belt to avoid deviation; The buffer idler is installed at the material receiving position to reduce the impact of the material on the belt. The drum is divided into driving drum and steering drum. The driving drum is the main part of power transmission, which is divided into single drum, double drum and multi drum. The function of the tensioning device is to make the conveyor belt reach the necessary tension, so as to avoid slipping on the driving drum, and ensure the deflection of the conveyor belt between the idlers within the specified range.

Advantages of  mobile belt conveyor 1.The mobile belt conveyor can be used in any place, no matter indoor or outdoor, it can work normally to minimize the operation in rainy days.2.The mobile performance is good, under normal circumstances, an adult man to move without any problems. It can be used in loading, material transfer and other occasions directly, and also suitable for logistics loading and unloading.3.Easy to operate, the machine is equipped with a control box, including a main control switch, a lifting switch. No need to be on duty, the machine can be started.

Common faults and solutions of belt conveyor1.The motor cannot be started. This situation is usually caused by line fault or voltage drop. At this time, we should check the line problem to see if there is a load of electrical appliances, or if there is a fault in the voltage line.2.Motor heating problemAfter we use the belt conveyor for a period of time, sometimes the equipment will cause the motor overload because of overload or transmission obstruction. In addition, there is no timely addition of lubricating oil, resulting in increased power. At this time, dust will accumulate in the fan or radiator of the motor, and the heat dissipation condition will deteriorate. At this time, you can test the power of the motor, find out the reason for the load, timely supplement lubricant is the best way.3.Conveyor Belt off trackThis situation is generally because the axis and the centerline are not perpendicular, or the conveyor belt joint deformation and so on. At this time, we need to adjust the frame or roller to ensure that the joint box conveyor belt base is straight.4.Aging of belt conveyor beltThis is usually due to the belt and frame conflict, or because of poor maintenance, resulting in too much tension, equipment aging early, affecting work. Sometimes it is also caused by the conflict between conveyor belt and some solid hard objects. In short, we should pay attention to this part, because this is the most common problem. In case of such situation, we should adjust the instrument in time to avoid long-term deviation of conveyor belt. Do not allow belt to collide with solid hard objects during operation.

First, the belt conveyor belt does not rotate. After the motor starts, the idling belt of the drive drum slips and the belt can not start. This kind of failure is caused by the insufficient belt tension, the tension device is not adjusted well, the belt is too long, heavy load start, and the tail of the belt is piled up with coal.Second, belt conveyor belt deviation. The reason for deviation is that the belt has lateral force in operation, and the reasons for the lateral force are as follows: the conveyor is loaded on one side, not installed in the center position; The installation axis of the idler and roller is not vertical to the center of the conveyor belt; The height of the steel wire rope of the fuselage is inconsistent; The connection of conveyor belt is not correct and straight; The position of the coal unloading drum is not adjusted well; The tail drum and guide roller can cause belt deviation if they are not adjusted well.Third, the belt conveyor belt is easy to be disconnected. This is caused by the belt tension is too large, the joint is not firm, the quality of the buckle is poor, the belt is used too long, the maintenance quality is poor, etc. the method is to tighten the tension device, reduce the tension and replace the new belt in time, and strengthen the maintenance quality.Fourth, the sound of the belt conveyor reducer is abnormal. This is caused by excessive wear clearance of bearings and gears or loose screw of housing. The treatment method is to replace bearings, adjust clearance or replace integral reducer for overhaul.

The characteristic of the wire rope traction belt conveyor is that the wire rope traction belt conveyor is a powerful belt conveyor. The characteristic of this kind of conveyor is that the steel wire rope is used as the traction mechanism, and the belt only plays a bearing role, not the traction force.The components of the belt conveyor are mainly composed of the transmission device, the upper and lower rollers, the intermediate frame, the reversing roller, the tensioning device, the cleaning device and the safety protection device.Belt conveyor is widely used in household appliances, electronics, electrical appliances, machinery, tobacco, injection molding, post and telecommunications, printing, food and other industries, assembling, testing, debugging, packaging and transportation of objects Wait. Line conveying can be selected according to process requirements: ordinary continuous operation, rhythm operation, variable speed operation and other control methods; line body is selected according to local conditions: linear, curved, slope and other line-type conveying equipment includes: belt conveyor, also called belt type Conveyor or belt conveyor, etc., are economical logistics conveying equipment that is indispensable for forming a rhythmic assembly line. Belt conveyors can be divided into heavy belt conveyors such as mining belt conveyors according to their conveying capacity, and light belt conveyors such as those used in electronic plastics, food, light industry, chemical and pharmaceutical industries. The belt conveyor has strong conveying capacity, long conveying distance, simple structure and easy maintenance, and can conveniently implement programmed control and automatic operation. The continuous or intermittent movement of the conveyor belt is used to transport articles under 100KG or powdery or granular articles. It runs at high speed, smoothly, with low noise, and can be transported up and down.SKE machinery is focusing on various belt conveyors design and manufacturing, please feel free to contact us if you have any interest.

The multi-point drive belt conveyor is also known as the middle power multi-point drive belt conveyor. In addition to the pulley drive device at the head of the machine, several sets driving devices are set in the middle of the conveyor. The characteristic of multi-point belt conveyor is that it can reduce the traction force of conveyor belt, and use ordinary braided conveyor belt to achieve the purpose of increasing the conveying distance.There are two types of multi-point drive belt conveyor: (1) linear friction multi-point drive belt conveyor: it is to add one or more ordinary belt conveyors (auxiliary machines) under the original conveyor (host) belt to support the synchronous operation of the main conveyor belt, and reduce the traction force of the main conveyor belt by friction; (2) the multi-point drive belt conveyor with intermediate drum unloading type: it is installed in the A driving point is added in the middle of the original belt of a telescopic belt conveyor to reduce the traction force of the belt.
