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.
Bucket elevators are not self-feeding, and are fed at a controlled rate. The buckets are usually where the chain or belt path is vertical or steeply inclined in a single plane. The buckets are returned back down to a tail pulley or sprocket at the bottom.
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.
Compact Machine Structure, small overall dimension, small space needed.
Adopt the taking out type material loading and mixing type material discharging. The hopper volume is big with high density layout. It has the feature of big lifting scope, high lifting height and high transportation capacity.
Each section and maintenance door have the sealing device to make sure no dust outlet to realize clean and friendly environment production.
Convenient operation and maintenance, compact structure

Note: The volume of the hopper in the table is the volume when the hopper is filled with water, which is similar to the actual filling volume. Therefore, the filling factor is not considered in the calculation formula of the conveying volume. The filling factor should be determined according to the particle size of the material in the specific selection, so as to correct the conveying volume given in this table.
