Thermal power plants use different types of coal pulverizers. The method used is attrition, impact, or a combination of both. This article explains the characteristics of the three main types- attrition, impact and attrition, and impact or hammer. Selection of the type of pulverizer depends on the grindability of the coal, the capital costs and maintenance costs, and considerations for licensing.

FOR COAL PULVERIZATION IS THE MOST PREFERRED AND UTILIZED MILL. The capacity in #/hr. of the mill is calculated on the assumption that the coal hardness is 55 on the Hardgrove Grindability Index and has a moisture content of 8%. This would then produce and output based on 70% of the coal passing through a 200 mesh screen.
