A belt conveyor is a machine that uses the endless movement of the belt to transport materials. The conveyor belt is wound around the driving roller and various diversion rollers, and the tensioning device provides the appropriate tensioning force. During operation, driven by the driving device, the conveyor belt is operated by the friction and tensioning force between the roller and the conveyor belt.

Materials are continuously sent to the conveyor belt and move with the conveyor belt, thereby realizing the transportation of materials.

How much do you know about the components of the conveyor? The following will take you through the components of the conveyor.

Parts of the conveyor belt system

The main components of belt conveyor include driving device, roller group, vertical tensioning device, idler group, sweeper, conveyor belt, safety protection device, etc.

Drive device

The driving device mainly consists of a motor, a hydraulic coupler, a reducer, a coupling, etc.

  • Motor reducers are standard components, and their structure and principle are not described too much.
  • Drive drum: The drive drum is the main component that transmits power, and the transport belt operates with the help of the friction between it and the drum. It consists of a cylinder, a shaft, and bearings. The driving roller is a diamond shaped groove with a cast rubber surface.
  • Turning the head to the pulley: mainly by increasing the wrap angle of the transport belt on the drive pulley to increase the friction between the drive pulley and the belt.
  • Tail diversion roller: mainly by increasing the wrap angle of the conveyor belt on the tail roller to increase the friction between the tail roller and the belt.

vertical take-up

It is mainly composed of up-down reversing rollers and counterweight rollers, which are used to tighten the counterweight roller through the counterweight to keep the entire belt in a taut state.

Idler assembly

The carrier roller group is a component that supports the conveyor belt and the materials on it. It is divided into slot type forward tilt carrier roller group, slot type carrier roller group, buffer carrier roller group, V-line forward tilt lower carrier roller group, and V-line lower carrier roller group.

Each idler group has light weight, low running resistance, and good sealing performance. Long service life and other characteristics. The buffer idler has the function of buffering the material and reducing the impact of the material on the conveyor belt.


The cleaning device includes a head cleaner and a return empty section cleaner. The function of the sweeper is to make the coal adhering to the belt fall off at a fixed place.

Belt protection device

Belt protection devices include belt-type anti-tearing, mesh type anti tearing, longitudinal tearing, underspeed, comprehensive protection, anti blocking, deviation, rope pulling, emergency stop, and other protection devices.

Common basic types of conveyor belts

The correct conveyor will effectively simplify your assembly line and improve profitability.

Belt conveyor

The belt conveyor has strong conveying capacity, long conveying distance, simple structure and easy maintenance, and can easily implement programmed control and automatic operation. It is widely used in various industries such as household appliances, electronics, electrical appliances, machinery, tobacco, injection molding, post and telecommunications, printing, food, and the assembly, testing, debugging, packaging, and transportation of objects.

Telescopic belt conveyor

A retractable belt conveyor is a conveyor equipped with a storage belt device on the body, which can adjust its length according to changes in the position of the working face.

roller conveyor

The roller conveyor mainly consists of rollers, racks, brackets, drive parts, etc. It has various structural forms and can transport materials with large single weight or withstand large impact loads. It is suitable for transporting various types of boxes, bags, pallets, and other pieces of goods. Bulk materials, small items, or irregular items need to be placed on pallets or transported in turnover boxes.

Screw conveyor

A screw conveyor is a machine that uses a motor to drive a screw to rotate and move materials to achieve conveying purposes. It can be transported horizontally, obliquely, or vertically, and has the advantages of simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance, and convenient closed transportation.

Spiral machines are widely used in various industries, such as building materials, chemical engineering, electric power, metallurgy, coal charcoal, grain, and other industries. They are suitable for horizontal or inclined conveying of powdery, granular, and small pieces of materials, such as coal, ash, slag, cement, grain, and so on. They are not suitable for conveying perishable, sticky, and caky materials.
