Bucket Elevator

Bucket elevator used for to convey loose material (Like Powder, Granuals) in limited space applications, in which vertical elevation and Z type also possible with help of buckets mounted on chain.A bucket elevator is a vertical material handling machine used to lift bulk materials (powder, grains, granules) from a lower level to a higher level using a series of buckets attached to a belt or chain. It is widely used in industries like food processing, agriculture, cement, chemicals, and packaging plants.

Working Principle

Material enters through the inlet at the bottom (boot section)

Buckets scoop the material

Buckets move upward with belt/chain

At the top, material is discharged by:

Centrifugal force OR

Gravity

Continuous vertical transport with minimal loss

Types of Bucket Elevators

1. Centrifugal Discharge Elevator

High speed

For free-flowing materials

2. Continuous Elevator

Low speed

For fragile materials

3. Chain Bucket Elevator

Heavy-duty

Used in cement & mining

4. Belt Bucket Elevator

Light to medium duty

Used in food & agriculture

Applications

Bucket elevators are used in:

🌾 Agriculture → grains, seeds

🍛 Food industry → rice, flour, pulses

🧱 Cement → cement, clinker

🧪 Chemicals → powders, pellets

🏭 Manufacturing → bulk material transfer

👉 Often used with:

Silos (storage)

Screw conveyors (horizontal transfer)

Key Features
