Cement Milling

This is done by a mixture of both air-cooling and water-cooling, including spraying water inside the mill. Cement milling and gypsum dehydration. Because the cement gets hot due to the heat generated by grinding, gypsum can be partly dehydrated, forming hemihydrate, or plaster of Paris - 2CaSO 4.H 2 O.
