The ball mill critical speed of various Intermittence Ball Mills is in direct proportion with its calculating critical speed in a ball mill crusher in India.
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.
