In the continuous food production, sometimes the material must be conveyed along the vertical direction or close to the vertical direction. Given belt conveyor inclination angle is supposed to be less than the repose angle of material on the conveyor, the angle of conveying material direction and horizontal direction should not be too big, in that case, bucket elevator should be used at this time.
Vertical lifting equipment is divided into hoist, tower crane, belt conveyor and bucket elevator. The former three kinds of equipment has the disadvantages of big area cover, low hoisting height and small capacity. The bucket elevator, on the other hand, has a high hoisting height, covering a small area and large capacity. Therefore, for the application needing long time vertical ascending in food production, usually bucket elevator was used as vertical equipment.
