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.
This handbook examines the intermediate and fine grinding of coal. Four coal grinding devices - three dry, one wet - are discussed with the appropriate ancillary equipment for complete systems. The mills examined are the: air-swept ball mill, roll or ball and race types of mills, air-swept hammer mill, and wet overflow ball mill.
Coal, lignite or petcoke are ground in the Pfeiffer vertical mill by using hot gases from a hot gas generator. The grinding plant can be inerted. The raw coal is dried while being ground in the mill even if feed moisture exceeds 25%. The feed size that can be handled is up to 100 mm, making two-step pre-crushing unnecessary.
