Cement milling and gypsum dehydration. Because the cement gets hot due to the heat generated by grinding, gypsum can be partly dehydrated, forming hemihydrate, or plaster of Paris - 2CaSO 4.H 2 O. On further heating, hemihydrate dehydrates further to a form of calcium sulfate known as soluble anhydrite (~CaSO 4). This is calcium sulfate with a ...
Michael Pollick Powdered gypsum is typically used to make plaster. Gypsum is the more common name for a mineral compound called calcium sulphate dihydroxide, or sulphate of lime. It is generally found underground near deposits of limestone or other minerals formed by evaporation. One of the most common forms of raw gypsum is a pure white crystal called alabaster.
