Belt conveyor is a continuous transport equipment with the belt as the traction bearing mechanism. The conveyor belt is wound through the driving drum and each reversing drum, and the appropriate tension force is given by the tension device. When working under the actuating device, the conveyor belt is operated by the friction between the
driving drum and the conveyor belt. Materials are continuously loaded on the conveyor belt and run together with the conveyor belt to realize the conveying of materials. This kind of conveyor conveying angle generally is 30 °, is widely used in food, feed, biomass energy and other industries and departments of bulk material transportation.
