What is chain bucket elevator?

Chain bucket elevator is a mechanical equipment that conveys bulk materials vertically or obliquely by chain-pulling hoppers. It is widely used in building materials, chemical industry, metallurgy, grain processing, mining and other industries. Its core function is to lift powdery, granular or small block materials (such as cement, coal powder, ore, etc.) from low to high to meet the needs of continuous production.

Features of Chain bucket elevator

High efficiency and energy saving: high torque motor and imported reducer are used to reduce energy consumption by 30%.

Wear-resistant and durable: the chain material can be selected from carbon steel, stainless steel or alloy steel, and the service life is extended by more than 2 years.

Modular design: standardized components (such as chains and hoppers) support rapid maintenance and replacement, reducing downtime.

Large conveying capacity: some models can lift up to 2300m³/h, and the lifting height can reach up to 90 meters.

Strong adaptability: abrasive or high-temperature materials (≤250℃) can be conveyed, such as cement clinker, limestone, etc.

Chain bucket elevator working principle

The chain bucket elevator uses a closed chain to pull the hopper in a circular motion, and the material enters the hopper from the bottom feed port; the chain drives the hopper to rise vertically; the material is discharged from the top by gravity or centrifugal force, and the empty hopper returns to the bottom, and the operation is cyclical.

Chain bucket elevator structure

Traction components: high-strength plate chain or ring chain, such as Portland/Ketten-Wulf chain, safety factor ≥12.

Hopper: divided into S type (powder) and D type (granules/small pieces), filling rate 60%~75%.

Drive device: motor + reducer, optional hydraulic coupling or magnetic coupling to improve starting stability.

Casing: carbon steel or stainless steel, sealed design to reduce dust spillage.

Tensioning device: The tail adopts an internal and external double tension structure to ensure stable operation of the chain.
