Free QuoteA Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell’s inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula The mill speed is typically defined as the percent of the Theoretical ...
Mar 17, 2017 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. Ball and SAG Mills are driven in practice at a speed corresponding to 60 …

Mill Critical Speed Determination. The Critical Speed for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell's inside surface. This is the rotational speed where balls will not fall away from the mill's shell. Result #1: This mill would need to spin at RPM to be at 100% critical speed.
