critical speed of cement ball mill - geofantasy.it
The effect of mill speed on kinetic breakage parameters. In this study, it was found that optimum grinding occurs at 85% of critical speed, compared to the optimum grinding at 70% of critical speed of the ball mill in the cement factory The variation of a T values with the fraction of mill critical speed ( φ c ) gave high correlation coefficients of 098 and 096 for clinker and limestone.
