Cement mill Wikipedia

Obtaining the optimum amount of rapidly soluble sulfate requires milling with a mill exit temperature within a few degrees of 115 °C. Where the milling system is too hot, some manufacturers use 2.5% gypsum and the remaining calcium sulfate as natural α-anhydrite (CaSO 4). Complete dehydration of this mixture yields the optimum 2% γ-anhydrite.
