A major portion of this power is installed to drive the unit equipment for the processes of comminution and smelting. Comminution is the process of rock size reduction, i.e. crushing and grinding. This size reduction is necessary to liberate the value minerals that naturally occur together in the run of mine ore.

GRINDING is a large and costly part of Portland cement manufacture. Prior to clinkering in the rotary kiln, raw materials are ground to a fineness of 80 to 90 pct passing 200 mesh. Then, after burning and cooling, the resulting clinker is ground to about 92 pct passing 325 mesh. In the cement industry the most favored method of grinding has always been by …
