Cement Mill Temperature Control

Cement mill - Wikipedia

Temperature control Heat generated in the grinding process causes gypsum (CaSO 42H 2 O) to lose water, forming bassanite (CaSO 402-07H 2 O) or γ-anhydrite (CaSO 4~005H 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 on their re-hydration causes "false set" - a …
