Bucket Elevator

The Bucket Elevator is used for conveying the material from lower level to higher level in the plant. The material entering at the bottom inlet is carried to the top by the bucket and discharged centrifugally in the outlet of the elevator. It consists of a rubber belt fitted with buckets at required intervals vertically and top and bottom pulley inside a fabricated steel casing (troughs). Sliding bearings are incorporated in the bottom pulley so that the tightness of the belt may be adjusted. The top pulley is rubberised to provide drive without any slip. Pawl-and-ratchet type back stop is provided on the top pulley to prevent reverse rotation due to the weight of the material on the active side of the belt. Bucket elevators are driven by a chain drive provided at the top through a geared motor or a worm reduction gear drive.
