How to Improve Cement Ball Mill Performance
1) The pre-crushing uses a crusher to crush the clinker before grinding, which can reduce the diameter of the clinker particles to 5 ~ 8mm. 2) The pre-grinding adds a roller press to the cement grinding system. In this system, the clinker is extruded circularly, dispersed and separated, and becomes powder with a diameter less than 2 mm;

Cement Milling
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.
