Bucket Elevators are the simplest and most dependable units for making vertical lifts and are available in a wide range of capacities and may operate entirely in the open or in totally closed.

Centrifugal Discharge Type Bucket Elevators are common buckets, are mounted at intervals on a belt or chain. The bucket elevator will handle any free flowing fine or small lump materials. The centrifugal style elevator operates at high speeds to throw the material by centrifugal action out of the buckets into the discharge spout as the buckets pass over the head pulley/sprocket. The buckets are spaced in wider intervals to prevent discharge interference from the proceeding bucket and to assure maximum fill of the buckets at the boot end while moving at higher speed.

Positive Discharge type Chain Bucket Elevators
Bucket elevator of this type is similar to centrifugal discharge except that the buckets are mounted on two strands of chain and are snubbed under the head sprocket to invert them for positive discharge. These units are designed for sticky materials.

Continuous Discharge type Bucket elevators
Continuous bucket elevators are designed to handle friable, fragile materials to minimize product degradation or damage or to handle sluggish or abrasive material. They are also used to convey light free-flowing matter where aeration of the material must be avoided. The continuous style elevator operates at a lower speed to minimize breakage of friable materials. The buckets are closely spaced on the belt or chain to allow the material to flow over the backside of the proceeding bucket, whose extended sides form a chute to guide the material into the discharge spout.
