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 grinding media are usually made of high- chromium steel. The smaller grades are occasionally cylindrical ("pebs") rather than spherical. There exists a speed of rotation (the "critical speed") at which the contents of the mill would simply ride over the roof of the mill due to centrifugal action.

As part of the grinding process, calcium sulfate is added as a set regulator, usually in the form of gypsum (CaSO 4 .2H 2 O). Natural anhydrite (CaSO 4) may also be added. Cooling is necessary to limit the temperature rise of the cement. This is done by a mixture of both air-cooling and water-cooling, including spraying water inside the mill.
