Pulverizer - Wikipedia

Beater wheel mills are designed to prepare a coal powder air-fuel mixture for combustion in furnace chambers of coal-freed power plants by coal drying, pulverizing, classifying and transport. Their multipurpose function usually results in operation instability accompanied by unacceptable vibration. This usually is a significant problem due to unplanned shutdowns. Beater wheel mill maintenance program requires special attention due to operation under non-stationary conditions.
