Bucket elevator

Bucket elevators are designed to move flowing powders or bulk solids vertically. Bucket elevators use an endless belt or chain and have a series of buckets attached to it. Bulk material is spread into an inlet hopper. Buckets (or cups) dig into the material and convey it up and over the head sprocket/pulley, and then throw the material out a discharge throat.

There are four broad classifications of bucket elevators: centrifugal, continuous, positive, and internal discharge. The most commonly used are the centrifugal and continuous discharge elevators. 

Centrifugal Bucket Elevators

Centrifugal bucket elevators are most commonly used to convey all free-flowing, powdered bulk solids such as grains, animal feed, sand, minerals, sugar, aggregates, chemicals and more. They operate at high speeds, which throw the materials out the buckets into discharge throats by centrifugal force.
