Gypsum is a crystalline form of hydrated calcium sulfate (CaSO 4 ·2H 2 0) generally used in cements and plasters in the construction industry, though also in paints, fertilizers, medicines, papers, and textiles. For use in these materials, gypsum must be ground finely (< 100 μm), if not ultra-finely (< 10 μm), for which ball mills are most effective.
