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.
Water injection helps to control the temperature in the mill. There are different causes of heat generation in the grinding process, so different water injection systems are required. For example, if the fresh material is very hot, water injection, e.g. clinker >120°C, a water injection system is used at the mill inlet.

The finished product leaves the mill at low temperature, so that extra cooling by water injection or coolers is not necessary. Costs of wear, maintenance and overhaul do not exceed those of the ball mills. ... The curve for the roller mill cement corres ponds fairly closely to the other two curves in the fin est particle size range, but is ...
Cooling by mill ventilation and water injection : Optionally by fresh air in separator and / or cement cooler. Variations in mill feed grindability can be equalized . ... Cooling by mill ventilation and water injection. Optional with cement cooler. Maintenance; Roller press: Low wear but very sensitive to foreign matters.
Cement manufacturing - brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.
