For cement grinding, normal mill capacities are between 100 and 200 TPH. Mill capacities depend greatly on the grind ability of the clinker and of the inter grinding material, such as slag or limestone, as well as on the required cement fineness. The mill output decreases in line with increasing product fineness.
