What are the differences between mining belt conveyor and ordinary conveyor

Mining belt conveyor is a conveyor that uses scraper chain to pull the belt and transport the materials in the tank. This machine is commonly used in coal mining and processing technology. It can maintain continuous operation and normal production and manufacturing can be carried out. Otherwise, all coal mining faces will be shut down, resulting in the final interruption of all production and manufacturing. What are the differences between mining belt conveyors and general conveyors? The following is a detailed introduction:

1. The principle is different

Basic principle of mining belt conveyor

The mining belt conveyor uses the open launder as the bearing part of coal, coal gangue or materials, and fixes the scraper on the sprocket (forming the scraper chain) as the prefabricated component of the traction belt. When the engine transmission system department operates, it drives the sprocket chain on the engine shaft to rotate, so that the scraper chain circulation system operates, and drives the materials to move along the launder until they are unloaded on the top of the machine head. The scraper chain bypasses the sprocket chain to operate as a non-polar closed cycle system for material transportation.

Screw conveyor is a kind of conveying machinery that uses the motor to promote the rotation of the blade surface in the equipment, so as to achieve its actual conveying effect. The belt conveyor is driven by the motor through the reducer motor. The conveyor belt is dragged by the sliding friction between the pushing barrel and the conveyor belt, and is transported to the dumping end through the column by the friction of the conveyor belt.

2. Different structure

Structure of mining belt conveyor

The mining belt conveyor has a firm structure, which is composed of three parts: the engine, the middle part and the tail end. The overall body is short, which is conducive to installation. It can also be used as the rail for the operation of shearers. It can operate in the opposite direction, which is conducive to solving the safety accidents of the bottom chain.

General conveyors include screw conveyor and belt conveyor. Belt conveyor is composed of transmission belt (adhesive tape), barrel, motor and other structures. Screw conveyor is composed of driving equipment, shell, rear cover plate, screw shaft, screw gear, feed inlet, feed inlet and other components.

3. Applicable materials are different

Mining belt conveyors are mainly used to transport materials from coal mining, organic chemical mining, metal mining and thermal power plants. They can be used for horizontal transportation or oblique transportation. When transporting upward along the skew, the inclination of the coal roadway shall not exceed 25 °. When transporting downward, the inclination shall not exceed 20 °. When the inclination of the coal roadway is too large, anti-skid devices shall be installed.

Generally, the conveyor can transport horizontally, askew or vertically, which is mainly used to transport powder, particles and small pieces of materials.
