bucket elevator types

Centrifugal bucket elevator

This type of bucket elevator uses centrifugal force to move the material through the buckets. The buckets are mounted on a belt or chain and are designed to discharge the material by centrifugal force as they reach the top of the elevator. Centrifugal bucket elevators are commonly used for handling fine or granular materials with low moisture content.

Continuous bucket elevator

In this type of bucket elevator, the buckets are designed to remain in a continuous loop, allowing the material to be fed into the elevator at the bottom and discharged at the top. Continuous bucket elevators are typically used for handling heavy, abrasive materials that require a sturdy and durable design.

Vertical bucket conveyor

This type of bucket elevator is designed to transport materials vertically between different levels of a building or production facility. The buckets are mounted on a belt or chain system and are designed to move the material up or down between different floors or levels.

Positive discharge bucket elevator

This type of bucket elevator is designed with a series of buckets that are mounted on a belt or chain and are filled with the material at the bottom of the elevator. As the buckets reach the top of the elevator, they are inverted to discharge the material into a chute or conveyor. Positive discharge bucket elevators are typically used for handling wet or sticky materials that require more precise control over the discharge process.
