### Ball Mill Critical SpeedMineral Processing Metallurgy

The Formula derivation ends up as follow Critical Speed is N c =76.6(D 0.5) where N c is the critical speed in revolutions per minute D is the mill effective inside diameter in feet. Example a mill measuring 11 0" diameter inside of new shell liners operates at 17.3 rpm. Critical speed is. C.S. = 76.63 / 11 0.5 = 23.1 rpm
