Chain Bucket Elevator

Vertical conveying of highly abrasive bulk materials less than 100 mm, chains available in different sizes with breaking forces up to 2,500 kN.

Lifting capacity: 800m³/h

Lifting height: 40 meters

Introduction of Chain Bucket Elevator

Chain bucket elevator is mainly used for conveying and lifting equipment with plate chain or ring chain. It is used to vertically lift powder, granular and small block materials, and the material temperature is below 250℃.

The hopper scoops up the material from the storage below, and along with the conveyor chain is lifted to the top, bypasses the top wheel and then turns down, and the bucket elevator dumps the material into the receiving trough.

Types of Chain Bucket Elevator

According to the different traction components, it is divided into two types: plate chain type and ring chain type: LEARN MORE

Plate chain bucket elevator: Using plate chain as traction member, self-flow charging and gravity discharge, it can not only lift general powder, granular and block materials, but also improve the material with high abrasiveness. ≤250 degrees. The chain is a high-quality alloy steel high-strength plate chain, which is wear-resistant and reliable. The drive part adopts a hard-tooth surface reducer, which runs smoothly.

Chain Bucket Elevator: Using circular chain as its traction member, it is mainly used for vertical conveying of powdery, granular and small block materials with high abrasiveness. The conveying capacity is increased by more than 30%, the lifting height is up to 50 meters, and the conveying capacity is as high as 365 cubic meters per hour.

Features and Benefits

1. The inflow feeding system is adopted, which can make the material lift almost without the phenomenon of returning and digging during the mechanical operation process, reducing the ineffective power.

2. The metal chain has a stronger bearing capacity and a breaking force of 2,500 kN, which is suitable for the lifting and conveying of large particles and heavy materials up to 40 meters.

3. Reasonable design principles and processing methods ensure the reliability of the whole machine operation, and the trouble-free time exceeds 20,000 hours.

4. Good sealing performance and less environmental pollution.

5. The material is conveyed in the vertical direction, so it occupies a small area and can effectively save space.

Structure of Chain Bucket Elevator

Chain bucket elevator is composed of running parts (hopper and traction member), upper section with drive sprocket, lower section with tension wheel, intermediate casing, driving device, backstop braking device and other parts.

Hopper: fixed on the traction chain, there are three types: deep hopper (suitable for loose materials), shallow hopper (material with high viscosity), triangular hopper (material with large specific gravity and lumpy).

Housing: Built-in transmission and brakes.

Body: thin steel plate welded into a square shell.

Bottom: install tensioning device.

Sprockets: Large and small sprockets are stamped and formed from high-quality carbon structural steel.

When should I choose to use Chain Bucket Elevator?

The Belt Type Bucket Elevator provides an efficient and economical option for handling light industrial products such as food and powder, and uses less noise (compared to the Chain Bucket Elevator).

However, the limitation of the Belt Type Bucket Elevator is that it is not durable enough. The Belt Type Bucket Elevator is not suitable for use when the product to be lifted is heavy, wearable, and has high temperature (above 150°C).

Therefore, the Chain Bucket Elevator is more suitable for mines and other large-capacity and high-lift operations that require strong handling. It is more wear-resistant and not easy to be damaged, and the metal chain will provide it with better bearing capacity and can adapt to higher temperatures. When the amount of material you need to convey is large and heavy, a double chain design can also be used.

Application

Chain bucket elevator is a plate-chain/loop-chain, gravity-induced unloading lifting equipment. NE series plate chain bucket elevator is suitable for vertical conveying of powdery, granular, small block abrasive or non-abrasive materials, such as raw meal, cement, coal, limestone, dry clay, clinker, etc.
