Mar 17, 2017 Charge movement at Various Mill Critical Speed. 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 …
The formula for critical speed is CS = 1/2π √ (g/ (R-r) where g is the gravitational constant, R is the inside diameter of the mill and r is the diameter of one piece of media. This reduced to CS = 265.45/√ (R-r). Dry mills typically operate in the range of 50%-70% of CS and most often between 60%-65% of CS.
