What is Belt Conveyor

belt conveyor

Belt conveyor is also called conveyor belt, which is a kind of transport machinery driven by friction and can transport materials in a continuous way. Belt conveyor is also an economic conveying equipment of logistics and has become an indispensable for assembly line operation.

Belt conveyor is mainly composed of 2 or more pulleys and closed conveyor belt on the tight sleeve. The pulley that drives the conveyor belt to rotate is called the driving pulley; the pulley that only changes the direction of the conveyor belt movement is called the reversing pulley or idler pulley. When working, the driving pulley is driven by the motor through the reducer, and the conveyor belt rotates by the friction between the driving pulley and the conveyor belt. Drive pulleys are usually installed at the discharge end to increase traction.

Belt conveyor system can be selected according to the process requirements: common continuous operation, beat operation, variable speed operation and other modes, and usually called “belt line, assembly line, conveyor, conveyor line”, etc. Which is widely used in coal plant, chemical industry, building materials, machinery, metallurgy, agriculture and logistics industry.

The simple and easy-to-use nature of the belt conveyor makes it one of the most common types of conveyor. In order to meet different needs, various types of belt conveyor are produced:

belt conveyor types



Cleated Belt Conveyor

The vertical cleats are distributed along the width of the belt in the cleated belt conveyor. The function of cleats are to support the material and realize the large angle transportation.

Cleated belt conveyor is widely used in coal, grain, building materials, chemical industry, hydropower and metallurgy industries. In the range of – 19 ℃ – + 40 ℃, it transports all kinds of easily scattered powder, granular, small block, paste and liquid materials with a stacking proportion of 0.5-2.5 t/m³.

Inclined Belt Conveyor

When materials need to be raised or lowered, it is often necessary to use inclined belt conveyors, but there is a certain limit to the tilt. Generally, the tilt up angle is not more than 18 °.

Flat Belt Conveyor

Flat belt conveyor has the general structure and characteristics of the belt conveyor, which is suitable for the transportation of irregular shape and light weight objects, such as postal parcels, clothes, paper products, plastic products, etc

The flat belt conveyor is divided into built-in motor type, head drive type and middle drive type.

Trough Belt Conveyor

Trough belt conveyor has a large loading and conveying capacity, the conveyor belt of the trough belt conveyor adopts multi-layer rubber belt, with the belt width of 500mm, 650mm, 800mm, 1000mm, 1200mm and 1400mm. The carrying side conveyopr belt is supported by a troughed idler that composed of 3 rollers (the angle of the trough can reach 45°), and the return idlers are supported by flat rollers.

Trough belt conveyors are widely used in electric power, iron and steel, mining, port, cement, grain, feed processing industry. Trough belt conveyors can transport bulk materials with large proportion such as coal, ore, soil, chemical raw materials, grain, etc., which are more suitable for a relatively poor production environment.

Roller Bed Belt Conveyor

Roller bed belt conveyor is a kind of conveyor which uses several rollers which are set up on the fixed support according to a certain distance to transport goods. Roller bed belt conveyor is suitable for all kinds of boxes, bags, pallets and other pieces of cargo transportation, mostly used for station or airport luggage sorting.

Roller bed belt conveyor can be used alone or in combination with other conveyors or working machines on the assembly line. It has the advantages of simple structure, reliable operation, flexible line layout, etc. According to whether the roller has driving device or not, the roller bed belt conveyor can be divided into two types: unpowered type and power type.

Portable Belt Conveyor

Universal wheels are installed at the bottom of the portable belt conveyor, which can move freely according to the stacking position of the materials, and are mostly used in the environment with small conveying inclination angle.

Portable belt conveyor is mainly used in places where loading and unloading places change frequently, such as ports, wharves, stations, coal plant, warehouses, construction sites, sand and stone plant, farms, etc., for short-distance transportation and loading and unloading of bulk materials or single weight of less than 100 kg of finished goods.

Retractable Belt Conveyor

The frame of the retractable belt conveyor is equipped with a storage belt device, which can make the belt stretch freely in the length direction and adjust the conveyor length according to the change of the belt working position at any time.

Retractable belt conveyor is the most efficient and commonly used machine in the continuous conveying of materials. It is the main equipment of coal conveying system in coal preparation plant and power plants.

Curved Belt Conveyor

Generally, the belt conveyor can only run in a straight line on a horizontal or vertical plane. To bypass obstacles or unfavorable sections, an intermediate transfer station needs to be set up, which has a high engineering cost. Curved belt conveyor realizes the natural curves of the conveyor by changing the arrangement angle of the idler group, reduces the transfer station numbers, and solves a series of problems brought by the transfer station.

Curved belt conveyor has been widely used in mining, metallurgy, chemical industry, power station and ports, especially for long-distance transportation.

Steel Belt Conveyor

Steel belt conveyor uses stainless steel belt instead of belt. For the belt conveyor will release harmful substances when conveying materials with high temperature, while the steel belt will not, steel belt conveyor is more suitable for material conveying in the food industry.

Special Belt Conveyor

Special belt conveyor is designed separately for the transportation of goods under special circumstances, which has a small range of applicability. Some of these are: magnetic belt conveyor, narrow belt conveyor, acid and alkali resistant belt conveyor, flame retardant belt conveyor, etc.
