INTRODUCTION
Belt Conveyor is a kind of machine that to transfer the material continuously. The belt works under the effect of frictional force. It is not only the components to transfer the material, but also the components to transfer the force. The Belt Conveyor is advanced and simple in structure, easy to maintain. Its transfer capacity is high, transfer distance is long. They are widely used in mining, metallurgical and coal industry to transfer sandy or lump material, or packaged material. In many situation, it Is a very important component of nonstandard machinery. 

WORKING PRINCIPLE
The conveyors consist of standard parts, such as the rubber conveyor belt, conveyor idlers and the screw feeder, which are advanced and simple in structure, easy to maintain. They are widely used in mining, metallurgical and coal industry to transfer sandy or lump material, or packaged material. According to different transferring equipment, the transfer system can be one independently or multi-conveyors or combined with other transfer equipments. The Belt Conveyor can be installed horizontally or aslope to meet the needs of different transfer lines.
The temperature of raw material can’t surpass 60°c.
The length and shape can be certain by user. Transmission available electric drum also can use tape drive rack driving devices.
Capable for conveying bulk density is less than 1.67 T/m3
