SAGMILLINGCOM Mill Critical Speed DeterminationBall mil design calculation Yahoo Answers

Mill Critical Speed Determination The Critical Speed for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell s inside surface This is the rotational speed where balls will not fall away from the mill s shellMar 31 32 The critical speed rpm is given by nC = /√d where d is the internal diameter in metr 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 allowing the use of different sizes of grinding media
