The beater wheel mill grinds the fuel to the required fineness and evaporates excess moisture from the fuel, while also ensuring the coal-air mixture is drawn into the combustion chamber. The bearings must withstand the harsh conditions at the limiting operating speeds, loaded both by external loads and by the mill wheel's unbalance.
