Background
The bucket elevator is a continuous conveying machine for vertically lifting materials by utilizing a series of hoppers uniformly and fixedly connected to an endless traction member, and the bucket elevator is divided into three types, namely a loop chain, a plate chain and a belt, for vertically or nearly vertically conveying bulk materials upwards by utilizing a series of hoppers fixedly connected to a traction chain or a rubber belt.
