COAL GRINDING AND DRYING IN CEMENT INDUSTRY
The raw coal has moisture content between 4 12 % by wt. and it is dried, in conjunction with grinding, to a residual moisture content of 0.5 1.5 % which is suitable for firing. The fineness to which coal should be ground depends on its flammability and combustion rates which are in turn, governed by the ash and volatile matter content.
