Jun 19, 2015 The mill speed is typically defined as the percent of the Theoretical Critical Speed, often abbreviated as %Cs. The Theoretical Critical Speed (Cs) of rotation is the speed (in RPM) at which an infinitely small particle will cling to the inside of the liners for a complete revolution. The percent of critical speed is the ratio (expressed as a percentage) of the actual mill speed and the Theoretical Critical
Mar 01, 2014 For 70% critical mill speed, Fig. 7 shows variation of S ** for 20/28 mesh size fraction of quartz with particle load at three levels of ball load, J 0.2, 0.3 and 0.4. It can be seen that all three curves exhibit a maxima. The U value corresponding to the maxima, U *, decreases as the ball load increases.
However, after reaching a critical speed, the mill charge clings to the inside perimeter of the mill. Under this conditions, the grinding rate is significant reduced or stopped. All mills must operate less than Critical Speed At position A, the media is held to the wall due to the following force balance Mg cos M2 / (R r)g

Cement ball mill critical speed ball mill critical speed mineral processing metallurgy a ball mill critical speed actually ball rod ag or sag is the speed at which the centrifugal forces equal gravitational forces at the mill shells inside.
Jul 31, 2014 Due to limitation of the mills rotational speed, the smallest ball size is usually restricted to about 15 mm. Cement grinding using stirred mills Pilevneli and Azizli, 1999 indicates that using smaller media 5-8 mm range improves grinding energy efficiency up to 50 using stirred mills.
