Cement mill - Wikipedia

Temperature control Heat generated in the grinding process causes gypsum (CaSO 4 .2H 2 O) to lose water, forming bassanite (CaSO 4 .0.2-0.7H 2 O) or γ-anhydrite (CaSO 4 .~0.05H 2 O). The latter minerals are rapidly soluble, and about 2% of these in cement is needed to control tricalcium aluminate hydration.
