Ball Mill Heat Balance Explanation - The Cement Grinding Office

It is well known that the biggest part of the energy introduced in a ball mill is converted into heat. -, Only around 5% of this energy is used to grind the material at the required fineness. -, As a consequence, this heat can induce very high temperatures inside the cement mill. -, These temperatures can affect the grinding.

Cement Milling - Understanding Cement

As part of the grinding process, calcium sulfate is added as a set regulator, usually in the form of gypsum (CaSO4.2H2O). Natural anhydrite (CaSO4) 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.
