Also known as conveyor belt, is the transmission medium in the conveyor belt system. The transmission belt system is a kind of transmission system, the system will include two or more pulleys, on which there are transmission belts, the pulleys can travel with unlimited rotation of the transmission belt. There will be one or more of the pulleys that are driven by power to allow the transmission belt to travel and carry the material that is transmitted on the transmission belt. Pulleys that are driven by power are called drive pulleys, and the rest are called idlers. There are two occasions for industrial application of transmission belts: in the factory, the material handling of conveying materials or objects in boxes or pallets, and the conveying of large quantities of materials or agricultural products (such as grain, salt, coal, ore, sand or Covering layer, etc.) bulk material handling.
