These speeds are 29.0%, 57.9%, and 86.9% of the critical speed given by the relation, Nc =42.29 D−1/2 [16], where Nc is the critical rotation speed (in rpm) and D is the inner diameter of the ball container (in meter).EFFECT OF BALL SIZE DISTRIBUTION ON MILLING PARAMETERS,2.4 Effect of ball size 29 2.4.1 Empirical approaches 29 2.4.2 Probabilistic approaches 33 2.5 Abnormal breakage 36 2.6 Effect of ball mixture 37 2.6.1 Ball size distribution in tumbling mills 37 2.6.2 Milling performance of a ball size distribution 40 2.7 Summary 41 Chapter 3 Experimental equipment and programme 43Ball Mill Critical Speed - Mineral Processing & Metallurgy,19-06-2015· Ball and SAG Mills are driven in practice at a speed corresponding to 60-81% of the critical speed, the choice of speed being influenced by economical considerations. Within that range the power is nearly proportional to the speed. Mill rotating speed impacts grinding rates.
