An air-swept coal mill is the core machine for pulverizing pulverized coal. However, according to our investigation, there are some problems with coal mills produced by many manufacturers. Therefore, our company has carried out a technical transformation on the air-swept coal mill to improve production efficiency and save energy.

Explosions consistently occur when the coal air mixture is leaner than normal, either when initating coal feed on mill start-up, stopping coal feed on shutdown, or when equip- ment problems cause inadvertent loss of feed. Upon loss of feed to a pulverizer, the coal air mixture in the system becomes leaner and the coal dust will.
