Mill Speed is one variable that can often be easily changed with a variable frequency drive (VFD) The starting point for mill speed calculations is the critical speed Critical speed (CS) is the speed at which the grinding media will centrifuge against the wall of the cylinder.Calculations The critical speed of ball mill is given by where R = radius of ball mill r = radius of ball For R = 1000 mm and r = 50 mm n c = 30 7 rpm But the mill is operated at a speed of 15 rpm Therefore the mill is operated at 100 x 15 30 7 = 48 86 of critical speed.
