The belt conveyor uses a conveyor belt as the traction and load‑bearing component. Its basic working principle is as follows: the conveyor belt forms an endless loop around the driving pulley and the take‑up pulley. The upper and lower belt strands are supported by idlers to limit deflection sag. During operation, the drive unit rotates the driving pulley, which drives the conveyor belt by friction between the driving pulley and the belt. Materials are placed on the upper strand of the conveyor belt and move forward together with the belt, then discharged at the end or designated discharge point. The take‑up device maintains sufficient belt tension to generate adequate friction between the driving pulley and the conveyor belt and prevent slipping. The idler sets support the belt and materials to reduce running resistance. The scraper cleans materials adhered to the belt surface to avoid carrying residues into the return strand.
