  • Ball Mill Critical SpeedMineral Processing Metallurgy

    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.

    critical a variable speed drive is recommended. This permits the operator to control his mill speed to suit. Most mills rotate at 60 to 65 percent of critical speed (Nc). This formulation is for wet milling where as dry milling needs to be adjusted by 2 to 5 RPM faster. These speeds hold true for any media regardless of shape for density.

    In the spindle system of the rice milling machine there are many asymmetric parts in the structure of the shaft and there are many curved grooves on the roller which leads to the existence of eccentric mass which will cause severe vibration when the rotation speed increases resulting in the broken rice rate. Increased bearing life is reduced.
