ball mills are always preferred to be operated at full capacity because the power consumption of this type of mill is very high at lower loads when compared with other types. ball mills can be designed for a very high capacity like 75 tons per hour output for a specific coal.
in the pressurized type, the hot primary air is used for drying the coal and to transport the milled coal to the furnace. in this type, leakage in the mill area is high.in the suction type, the exhauster is used for lifting the milled coal from the pulverizer to the furnace through a cyclone.

the coal formation process involves the burial of peat, which is made of partly decayed plant materials, deep underground. the heat and pressure of burial alters the texture and increases the carbon content of the peat, which transforms it into coal, a type of sedimentary rock. this process takes millions of years. types, or ranks, of coal are determined by carbon content.
