Silo Bucket Elevator

The special bucket elevator for silos is a vertical and sealed conveying equipment specifically designed for use in steel silos, cement silos, grain silos, and powder storage silos. It discharges by centrifugal force, lifting the granular and powdered raw materials from the ground and pits to the top of the silo vertically, and delivering the materials into the silo for storage. It is the core feeding equipment of the bulk material storage system. It has advantages such as compact structure, environmental protection, low material fragmentation during transportation, and the ability to operate continuously. Additionally, the hopper can be made of carbon steel, stainless steel, or polypropylene (PP) materials according to the characteristics of the materials.

 

 

The motor drives the head wheel to rotate the belt/chain in a circular motion. The hopper fixed on the traction piece scoops the material at the bottom of the equipment, lifts it vertically upwards along the sealed casing, and discharges the material at the top of the silo by centrifugal force. The material then falls into the interior of the silo for storage. The empty hopper then cycles back down and continues to feed materials, achieving continuous automatic feeding into the silo.

 

 

 

 Chain Type

Suitable for most silo scenarios, especially when the material particle size is > 20mm, there is abrasiveness (such as cement clinker, limestone, lump coal), the temperature is > 60℃, or a large transportation capacity is required. The plate chain is lighter in weight than the loop chain, has high strength, is wear-resistant, and supports high-speed operation (up to 1.1m/s). It is the mainstream configuration for modern large silos.

 Band Type

Suitable only for powdery/finely granular materials with particle size < 20mm (such as flour, fine sand), with a temperature of ≤ 60℃ (for ordinary bands) or ≤ 120℃ (for heat-resistant bands). It is suitable for scenarios that are sensitive to noise, require low energy consumption and low cost. The traction component has low tensile strength and is not suitable for heavy loads or high impact conditions.
