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

Rotary Silo Blockage Cleaning Machine with external-mounted scrapers for raw-coal hopper block-up solving

Rotary Silo Blockage Cleaning Machine

The Rotary Silo Blockage Cleaning Machine is designed to mechanically remove existing blockages inside industrial silos and restore stable material discharge. It is suitable for severe material bridging, arching, compacted material, wall buildup and other blockage conditions that interrupt silo flow.

Common Silo Blockage Problems

During storage and discharge, bulk materials may cause:
• Material bridging
• Wall buildup
• Poor discharge flow
• Material compaction
• Silo outlet blockage

Key Features and Advantages

Effective Blockage Removal

• bridging

• compacted material

• wall buildup

Reduce Manual Cleaning

• less labor requirement

• improved safety

• reduced downtime

Improve Material Discharge

• stable feeding

• continuous production

Customized Design

• silo diameter

• material characteristics

• installation conditions

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

What causes silo blockage?
Silo blockage is usually caused by material bridging, moisture, compaction and poor flow characteristics.
How does the rotary silo cleaning machine remove blockage?
The rotary mechanism loosens accumulated materials and helps restore normal discharge flow.
What industries use this equipment?
It is widely applied in thermal power plants, cement plants, steel mills, chemical plants and mining for fly ash, coal powder, cement raw meal and other sticky bulk solids.
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.
