How does Chain Elevator work?

The working principle of Chain Elevator is based on the cooperation of chain and lifting bucket. The chain of the equipment is driven by an electric motor and a reducer to drive the lifting bucket to rise and fall vertically along a fixed track. The material enters the hopper through the feed port and is discharged through the discharge port after the lifting process.

How to select Chain Elevator?

1. Material characteristics

The characteristics of the material directly affect the design and selection of the elevator. The following are several aspects to consider when selecting a chain elevator based on material characteristics:

Material type:

Granular, powdery, block materials: Chain elevators are suitable for these materials, especially block materials (such as coal, ore, crushed stone, etc.) and granular materials (such as cement, fertilizer, grain, etc.). Sticky materials: If the material is sticky (such as wet clay, wet sand, etc.), you need to use a specially designed hopper, such as an anti-stick hopper, to prevent the material from sticking to the hopper or chain and causing blockage.

Material density: The density of the material determines the load requirements of the elevator. For heavy materials (such as ore, coal, etc.), you need to choose a higher strength chain and a larger capacity hopper.

Material temperature: If the temperature of the conveyed material is high (such as hot cement, steel raw materials, etc.), you need to choose a high temperature resistant chain, hopper and sealing design.

Material corrosion: For highly corrosive materials (such as fertilizers, chemical powders, etc.), you need to choose corrosion-resistant chains and hopper materials, such as stainless steel or coated materials.

Material humidity: Materials with high humidity may adhere to the equipment, causing blockage or wear. Therefore, when selecting, you need to consider designs with self-cleaning functions or heating devices to reduce adhesion and blockage.

2. Lifting height

The lifting height affects the structure and drive power selection of the chain hoist. Generally, when the lifting height is high, the chain load and driving power requirements will increase, so:

Low lifting height (10-20 meters): suitable for small enterprises or medium and low-rise buildings, the equipment selection is relatively simple, and the main focus is on the conveying capacity and material characteristics.

Medium lifting height (20-40 meters): suitable for medium-sized enterprises or places with high material conveying needs, it is necessary to select a more powerful drive system and a higher strength chain.

High lifting height (above 40 meters): requires a stronger chain, drive device and reinforced structural design, and the price and power requirements of the equipment will increase accordingly.

3. Lifting capacity (conveyance)

Lifting capacity (conveyance) refers to the amount of material that the elevator can convey per unit time, usually in tons/hour (t/h). Determine the conveying capacity according to production needs:

Low lifting capacity (10-30t/h): suitable for small-scale or medium-to-low-volume production environments, suitable for small cement plants, grain processing plants, etc.

Medium lifting capacity (30-100t/h): suitable for medium-sized production lines, commonly seen in medium-sized mines, fertilizer plants, food processing plants, etc.

Large lifting capacity (above 100t/h): suitable for large production lines, especially large cement plants, mines, chemical plants, etc., requiring equipment with stronger pressure resistance and large-capacity hoppers.

4. Chain and drive system

Chain and drive system are key components of chain hoists, and choosing the right chain and drive device is crucial.

Chain material and type:

Carbon steel chain: suitable for general materials, relatively economical price, and bears general load.

Alloy steel chain: suitable for high-load and high-strength applications, such as mines and heavy material transportation.

Stainless steel chain: used for material transportation in corrosion-resistant, high-temperature or special environments.

Wear-resistant chain: suitable for occasions where material particles are large and have greater friction, such as coal, ore, etc.

Drive power: select the drive power according to the lifting height, conveying capacity and material type. Higher lifting heights and large conveying volumes usually require higher power motors (such as 5.5kW to 45kW).

Drive mode: Chain hoists can choose different drive modes, including direct motor drive, hydraulic drive, etc. Motor drive is the most common method, and hydraulic drive is suitable for more special applications.

5. Hopper design

The hopper is an important part of the chain hoist. Choosing the right type of hopper can improve conveying efficiency and reduce material waste.

Standard hopper: suitable for general granular materials, such as cement, grain, etc.

Enlarged hopper: suitable for materials with larger particles or higher density, such as coal, ore, etc.

Anti-stick hopper: used for wet or sticky materials to prevent material adhesion.

Anti-corrosion hopper: suitable for highly corrosive materials such as fertilizers and chemical materials, commonly using stainless steel or coated materials.
