2020-5-22 · Gypsum rock is first mined or quarried, then crushed and ground to a fine powder. It then goes through a process called calcining where heat at 350 degrees is supplied to the gypsum powder which removes 3/4 th of the water molecules. Hemihydrate is the name of calcined gypsum which is then used in gypsum board, gypsum plaster, and other products.

Ball Mills an overview ScienceDirect Topics
Grinding is an energy intensive process and grinding more finely than necessary wastes energy. Cement consists of clinker, gypsum and other components mostly more easily ground than clinker. To minimise over-grinding modern ball mills are fitted with dynamic separators (otherwise described as ‘classifiers’ or more simply as ‘separators’).

Tricalcium Silicate an overview ScienceDirect Topics
Portland cement is produced from clinker by grinding with approximately 5 per cent natural gypsum (usually composed of a mixture of calcium sulfate dihydrate, CaSO 4 ·2H 2 O, and anhydrite, CaSO 4), in order to regulate the setting time of the cement. Portland cement is ground until more than 90 per cent passes through a 90 μm sieve.
