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 sizemills including a roller press are mostly single-chambered) allowing the use of different sizes of grinding media.
