Ball Mill Critical Speed

2015-6-19 · Critical speed is. C.S. = 76.63 / 11^0.5 = 23.1 rpm. Ball and SAG Mills are driven in practice at a speed corresponding to 60-81% of the critical speed, the choice of speed being influenced by economical considerations. Within that range the power is nearly proportional to the speed. Mill rotating speed impacts grinding rates.
