    Grinding. The clinkers as obtained from the rotary kiln are finely ground in ball mills and tube mills. During grinding a small quantity about 3 to 4 percent of gypsum is added. The gypsum controls the initial setting time of cement. If gypsum is not added the cement would set as soon as water is added.
