Section snippets Experimental work. The same lots of Portland cement clinker and natural gypsum (CaSO 2 O) were used in this industrialplantscale experimental work to eliminate the potential effects of variations in the feed to the grinding systems. Chemical compositions of the clinker and the gypsum, measured by Xray fluorescence analysis, are given in Table 1.

Roller mills have sets of grinding rollers that rotate above a grinding table which travels in a circular path, and a classifier that is mounted above the rollers and the grinding table. Roller mills are designed to pulverize and classify solid materials such as clays, clinker, gypsum, natural pozzolan, limestone, and blast furnace slag.
