Grinding- The klinkers, so obtained from the rotary kiln, are ground to the required degree of fineness in a ball mill or a tube mill.During grinding, a small quantity of gypsum (about 3% to 4%) is added. Gypsum controls the initial setting time of cement. If gypsum is not added, the cement would set soon as water is added to it. thus, gypsum acts as a retarder, and delays the initial setting
