Many thermal power plants struggle with frequent raw coal bunker blockage, and the root cause often lies in the structural design of raw coal bunkers. The lower section of raw coal bunkers comes in four mainstream structural forms: rectangular tapered section, conical section, rectangular hyperbolic section and circular hyperbolic section. Each structure delivers different coal flow performance and carries varying blockage risks. This directly affects how often you need to run an arch breaker machine. Mastering these structural differences helps you select targeted silo blockage clearing equipment and chute blockage cleaning machine to eliminate coal buildup and material arching permanently.
Why Raw Coal Bunkers Become Blocked
（1）Rectangular Section Coal Bunker: High Coal Accumulation Risk at Wall Corners
（2）Conical Coal Bunker: Falling Flow Power Triggers Frequent Blockage
（3）Hyperbolic Coal Bunker: Improved Flow Performance With Obvious Limitations
Traditional Coal Bunker Arch Breaking Methods and Limitations
Traditional coal bunker arch breaking solutions mainly include manual cleaning, air cannons and vibration equipment. These measures mostly deal with blockages after they occur and often require shutdown maintenance. They have obvious limitations such as narrow effective range, poor performance for high-viscosity wet coal, potential damage to silo structures, high safety risks and frequent recurrence of blockage. Many power plants are turning to intelligent automatic anti-blocking machines for continuous online prevention.
Intelligent Variable Inclination Vortex Arch Breaker Machine: Universal Solution for All Silo Structures
Every raw coal bunker structure has unique blockage mechanisms, so traditional simple dredging methods cannot deliver thorough cleaning. Our Intelligent Variable Inclination Vortex Arch Breaker Machine and supporting chute blockage cleaning machine are developed to fit all types of coal bunkers.
Equipped with variable inclination vortex rotary cleaning structure and intelligent frequency conversion control system, the equipment achieves dead-angle-free cleaning for corner coal buildup in rectangular bunkers, compensates insufficient flow power inside conical bunkers, and assists dredging for high-humidity coal inside hyperbolic bunkers.
The machine effectively solves typical pain points including wall-attached coal, material arching and insufficient flow capacity. It cuts manual maintenance workload and avoids economic losses caused by unexpected shutdowns due to silo blockage. As high-performance industrial silo blockage clearing equipment, it adapts to all common coal bunker structures and severe humid working conditions.
