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.
Nowadays, ball mills are widely used in cement plants to grind clinker and gypsum to produce cement. The research focuses on the mill speed as well as air classifier speed effect on the two compartment Cement ball mill performance in terms of Blaine, Sulphur xide contents, mill power, mill residue and mill residence time.
