After cooling, the clinker may be stored temporarily in a clinker store, or it may pass directly to the cement mill. The cement mill grinds the clinker to a fine powder. A small amount of gypsum - a form of calcium sulfate - is normally ground up with the clinker. The gypsum controls the setting properties of the cement when water is added.

This system is usually combined with a roller press and a cement mill. The clinkers are first ground in the roller press, and then screened and graded by the separator. Part of the materials return to the roller press for regrinding, and the qualified materials enter the cement mill for further grinding. Compared with the first two grinding ...

The mills are of the rotary ball type (previously described). The process consists of grinding the clinker with about 5 percent gypsum to regulate the setting time of the cement. The finishing mills are sometimes sprayed with water to keep them sufficiently cool and to minimize dehydration of the gypsum, which could lead to "false set" problems.
