The belt conveyor mainly includes pipe conveyor(pipe belt conveyor), downwards transportation belt conveyor, plane turning belt conveyor, coal mine belt conveyor. The belt conveyor is basic mechanical equipment in the mining working. It could convey materials for various mining equipment, such as stacker reclaimer. It could be regarded as the link among various mining equipment. The belt conveyor has features of simple structure, and easy maintenance. It consists of conveyor belt, pulley, idler, frame, tensioning frame and sweeper. The pulley of belt conveyor could be divided into transmission pulley and bend pulley. The transmission pulley is connected to the motor and reducer, while the bend pulley controls the conveying direction.
The conveyor pulley, as one of the conveyor components, uses multi-metal wear-resisting material that is coherent to the surface of pulley instead of the conventional rubber layer. Standard life span can reach more than 50000 hours (6years). As per GB/T 10595-2009 (equivalent to ISO-5048), life span of pulley bearing shall be more than 50000 hours which means clients can maintain the bearing and pulley surface at the same time. Max life span can be more than 30 years. The surface and internal structure of multi-mental wear-resisting material is porous. The groove on the surface will increase the resistance coefficient and slip resistance. Conveyor pulley has a performance in heat dissipation especially in high temperature condition. Decay resistance is another advantage of drum pulley. It can also achieve a good performance at the seaside or some other complex condition. High hardness of the surface will prevent the foreign body(scrap iron or dina) from inserting into the pulley and protect the belt thereby.
