After ventilation, the use of water sprays is one of the principal means of control- ling airborne respirable dust in coal min- ing operations. Water sprays have been initially reported to reduce airborne res- pirable dust from 20% to 60% by Kobrick (1969). A U.S. Bureau of Mines labora-
desuperheating spray water flows, etc. Given the above, the true definition of pulverizer capacity is the coal throughput at a given fineness, Hardgrove grindability, moisture content and raw coal size. All of these factors should be considered when optimizing your mills' performance. The Major Mechanical Factors Related to Capacity

b. Coal with very high moisture content derates the capacity of mills and requires higher quantum of heat for coal drying in the mill thus necessitating higher hot air temperature at mill inlet and thus impacting sizing of economizer and air pre-heater. If low moisture coals are used, heat required to dry the coal is less thus air passing

Coal Grinding. To achieve good combustion and satisfactory flame formation, coal needs to be dried and ground to a proper degree of dryness and fineness. Drying of moisture in coal is achieved normally by ducting part of the kiln exhaust gas through the mill with inlet temperatures of up to 300°C. Inert kiln exhaust gases with oxygen content ...
