Cement mill Wikipedia

Ball mills are normally operated at around 75% of critical speed, so a mill with diameter 5 metres will turn at around 14 rpm. The mill is usually divided into at least two chambers (although this depends upon feed input size mills including a roller press are mostly single-chambered), allowing the use of different sizes of grinding media.

An experimental study on the ultra-fine grinding of gypsum

Apr 01, 2016 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.
