Cement mill - Wikipedia

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. If more than this amount forms, crystallization of gypsum ...
