19/06/2015· 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 60-81% of the critical speed,
