Pulverizing mills in boiler plants play a major role in preparing the coal for firing in a boiler. Coal, being a heterogeneous fuel, varies in its properties the variation depends on many factors like type of origin of coal, formation, etc.Two major parameters which decide the mill capacity and performance are the hardness of the coal and the total moisture level in coal.
