Coal is the one of the most dominating energy source because of its cost, availability and transportability. Pulverized form of coal has made modern steam generating units highly thermal efficient, reliable, safe and able to efficiently use of low-grade coals. It provides coal-air fuel control, flame stability, effective utilization of carbon and thus reduction in cost and flexibility of operation. The efficiency of combustion depends upon efficiency of pulverizing. Grinding mills use one , two or all three of the basic principles of particle size reduction namely impact, attrition and crushing. With respect to speed these machines may be classified as low speed, medium speed and high speed. The characteristics of commonly used pulverizes are shown in the table below
