### How can I determine the best RPM for Dry Ball Milling

2019/10/28 · Critical speed (in rpm) = 42.3/sqrt(Dd) with D the diameter of the mill in meters and d the diameter of the largest grinding ball you will use for experiment (also expressed in meters) 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.
