• The coal is made of pulverized coal by the coal mill mainly through the three ways of crushing shredding and grinding. Among the three ways the energy consumption of the crushing process is the smallest while that of the grinding process is the most. The milling process of the various coal mills contains two or three ways of the above-mentioned.
