Cement mill - WikipediaHeat generated in the grinding process causes gypsum (CaSO4.2H2O) to lose water, forming bassanite (CaSO4.0.2-0.7H2O) or γ-anhydrite (CaSO4.~0.05H2O). The latter minerals are rapidly soluble, and about 2% of these in cement is needed to control tricalcium aluminate hydration. If more than this amount forms,.alternative cement milling process,An Overview of Cement production: How “green” and sustainable is .byproducts from other industrial processes, are highlighted and analysed.

Cement Milling - Understanding Cement

Vertical roller mills (VRMs) are the main alternative means of grinding the clinker and are increasingly being used. See, for example, this page on the FL website (opens in new tab or window). As part of the grinding process, calcium sulfate is added as a set regulator, usually in the form of gypsum (CaSO4.2H2O).
