Aug 01, 2004 Aug 01, 2004 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 0.98 and 0.96 for clinker and limestone, respectively, through a regression analysis
