Chain Bucket Elevator

A Chain Bucket Elevator is a heavy-duty vertical conveying machine that adopts high-strength steel chain as traction parts.It is mainly used for continuous vertical lifting of bulk granular,block and powdery materials.Compared with belt-type bucket elevators,it features higher load capacity,better wear resistance and high temperature resistance,widely applied in mining,cement,building materials,metallurgy and chemical industry.

Working Principle

Driven by the motor and speed reducer,the driving sprocket at the top rotates to drive the closed chain loop running.The hopper buckets are evenly installed on the chains.Materials enter the bottom base of the elevator and are scooped up by the moving buckets.With the circulation of chains,materials are lifted vertically to the top discharge port.Then the buckets turn over and unload materials by gravity unloading method,and empty buckets return to the lower part for next cycle.The whole conveying process is fully enclosed.

Main Characteristics

Solid chain transmission structure

Adopts forged round-link chain with high tensile strength,strong wear resistance and long service life.It can bear heavy load impact and is not easy to break or slip.

Excellent high temperature resistance

Suitable for conveying high-temperature bulk materials,the maximum bearable material temperature can reach 250℃.

Stable and reliable operation

Equipped with anti-reverse backstop device,which effectively prevents chain reversal and material backflow caused by sudden power failure.The lower part is equipped with automatic tension device to keep chain tension stable.

Strong adaptability to materials

Able to handle abrasive,heavy,wet and slightly viscous bulk materials which are not suitable for belt elevators.

Sealed and dustproof casing

Fully enclosed shell structure avoids dust leakage,improves working environment and prevents material loss.

Convenient maintenance

Sprocket wheel with replaceable rim,easy to repair and replace vulnerable parts.

Common Series Models

Typical chain bucket elevator series include TH Series and HL Series.

TH Series:Round link chain bucket elevator,the most widely used heavy-duty model.

HL Series:Plate chain bucket elevator,for larger capacity and ultra-high lifting height working conditions.
