HNMY provides mechanical equipment for silo blockage removal, material flow assistance, coal chute blockage cleaning, and controlled bulk material discharge

Silos Wall Flow-Assisting Blockage Removal Device

The Silo Wall Flow-Assisting Device is designed to improve material movement along the silo wall and reduce problems caused by material adhesion, buildup and poor flowability. It provides mechanical flow assistance for bulk materials that tend to stick to silo walls or discharge unevenly.

Common Silo Flow Problems

Bulk materials stored in silos may cause:

• Material sticking on silo walls

• Wall buildup

• Bridging formation

• Reduced outlet flow

• Unstable feeding process

How Does the Silo Wall Flow Aid Work?

Key Features and Advantages

Prevent Material Buildup：Helps reduce material accumulation on silo walls and improves storage efficiency.

Improve Material Flow：Supports stable discharge of difficult-flowing bulk materials.

Reduce Manual Cleaning：Reduces the need for manual blockage removal and improves operation safety.

Suitable for Difficult Materials：Designed for materials with poor flowability and strong adhesion characteristics.

Applications

This system is designed for silos handling high bulk density materials (≤4.8 t/m³) with extremely poor flowability, high viscosity and a tendency to form blockages.

✓ Iron ore powder silos in steel plants

✓ Limestone storage silos

✓ Sintering and pelletizing plant mixing silos

✓ Raw material storage silos

✓ Coal bunkers in coal-fired power plants

✓ Coal slime and sludge storage silos

It is especially suitable for high-density, low-flow-rate bulk material storage systems where material buildup, bridging, arching and wall adhesion frequently occur. The equipment helps maintain continuous material discharge, reduce manual cleaning operations and improve the reliability of bulk material handling systems.

FAQ

Why do materials stick to silo walls?

Material adhesion is usually caused by moisture, cohesion, electrostatic effects and wall friction.

Can this device prevent silo blockage?

Yes. It helps reduce material buildup and improves flow conditions to prevent blockage problems.

What industries use silo flow assisting devices?

It is widely used in cement, power, steel, mining and chemical industries.

Can the equipment be customized?

Yes. We support custom dimensions, power, control modes (manual / servo detection / intelligent timing module) to match your silo parameters and working conditions.
