Bucket Elevator is a continuous conveying machine that vertically lifts materials using a series of buckets uniformly mounted on an endless traction element. The buckets, fixed on a traction chain or belt, transport loose materials upwards vertically or nearly vertically. They are categorized into three types: Ring Chain, Plate Chain, and Belt.
The screw conveyor mainly conforms to the performance and parameters specified in JB3926-85 "Vertical Screw Conveyors" (this standard is equivalent to international and advanced foreign standards).
