Working principle: The conveyor belt is tensioned by the driving device, and the middle frame and the idler roller constitute a conveyor belt as a traction and bearing member, thereby continuously conveying the scattered materials or pieces.

The belt conveyor has strong conveying capacity, long conveying distance, simple structure and easy maintenance, and can easily implement program control and automation. The belt conveyor uses continuous or intermittent movement of the conveyor belt to transport items below 100KG or powdery or granular items. It runs at high speed, is stable, has low noise, and can be transported up and down.
