Gangue bucket elevator

 What is gangue bucket elevator?

Gangue bucket elevator is a kind of equipment specially used for vertical transportation of bulk materials such as gangue, ore, coal, etc. It lifts materials from low to high through a hopper fixed on a chain or belt, and is widely used in mining, metallurgy, building materials and other industries.

What are the functions of gangue bucket elevator?

Vertical transportation: Efficiently lift bulk materials such as gangue from low to high.

Large-capacity transportation: Suitable for large-tonnage and ultra-high-altitude material transmission, with large lifting capacity.

Good sealing performance: Reduce dust pollution and improve the working environment.

Strong wear resistance: Use high manganese steel or polymer wear-resistant lining to extend the life of the equipment.

Safe and reliable: Equipped with safety devices such as speed, deviation, blockage and temperature detection to ensure stable operation.

What are the applications of gangue bucket eleva​tor?

Mining industry: Used for vertical transportation of gangue, ore and coal.

Metallurgical industry: Transport metallurgical raw materials and waste.

Building materials industry: used for lifting cement, limestone and other materials.

Ports and docks: used for loading, unloading and transshipment of bulk materials.

Energy industry: transporting coal and ash in thermal power plants.

How does gangue bucket elevator work?

When Gangue Bucket Elevator is working, Gangue enters the hopper from the bottom feed port, and the hopper is driven by a chain or belt to lift the gangue to the top; it is unloaded at the top by centrifugal force or gravity, and the empty hopper returns to the bottom to complete a cycle.

What are the structures of gangue bucket eleva​tor?

Head device: including drive wheel, backstop and discharge port.

Tail device: including tension wheel and self-cleaning structure to prevent material adhesion.

Hopper: high-strength plastic or iron hopper, wear-resistant and large capacity.

Chain or belt: used to fix and drive the hopper.

Casing: sealed design to reduce dust leakage.

How to select Gangue Bucket Elevator?

Gangue Characteristics (Abrasiveness and Moisture)

High Abrasiveness: Gangue (coal/mining waste) is abrasive and requires wear-resistant materials (e.g. NM400 steel buckets, manganese steel chains) to reduce maintenance.

Moisture Content: Wet gangue may stick to buckets; choose perforated buckets or anti-fouling coatings to prevent material buildup.

Lift Height and Capacity

Height: Choose a lift with a lift range of 20-50m for typical gangue transport (e.g. coal mines, power plants)1. Higher lifts (>50m) may require reinforced chains.

Capacity: Small: 10-50 T/H (e.g. recycling plants); Industrial: 80-150 T/H (e.g. cement plants, coal processing).

Material and Durability

Bucket/Chain: Stainless steel (food grade applications) or hardened steel (mining/cement) for corrosion/wear resistance.

Frame: Carbon steel with anti-corrosion paint for harsh environments.

Bucket Type

Deep bucket: For fine/powdered gangue (e.g., coal ash).

Shallow bucket: For lumpy gangue (e.g., mining waste).

Perforated bucket: For wet gangue to facilitate drainage.

Power and drive system

Motor: 5.5–30 kW, depending on load and speed. Variable frequency drive (VFD) adjusts speed for different gangue loads.

Drive: Chain drive: Heavy duty (e.g., mining), high torque; Belt drive: Low maintenance for light loads.
