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.

coal characteristics on grinding capacity and energy consumption was carried out. Based on coal characteristics and values of HGI, mathematical expressions were derived for the calculation of grinding capacity and electric energy consumption. In addition, ability to predict specific power consumption of the mill on the basis of HGI values, were

Cold Air Locking at Mill Inlet: This is very important for coal mill, as ambient air throttling the drying capacity of mill as well as increases the oxygen content of kiln gases making it riskier. Oxygen percentage of more than 12-14% is considered catalyst for fire/explosion risk.

All mill capacities are based on a standard coal with HGI = 50. The larger the value for HGI, the easier it is to grind the coal, resulting in a higher mill capacity. An HGI of 35 reduces the mill capacity about 20%. Coals with HGI less than 35 can be pulverized, but mill capacities are reduced significantly.

The dashed line estimates the increase in mill capacity in going from a high-volatile B bituminous coal with a 55 HGI, 12% moisture and a desired mill output of 70% through a 200 mesh screen to a highvolatile B bituminous coal with an HGI value of 60, a moisture content of 14% and the same fineness.

Mill capacity increases linearly with increasing ball load for both ball sizes within the considered range. The 30 mm ball draws slightly more power as J increases from 11 to 16% but the gain in capacity is much more. In fact for an increase in J from 11 to 16% (i.e. 45% increase), power draw increase is 31%, while capacity increases by 51%.
