The specific selection function effect on clinker

2008-7-2  The maximum energy efficiency factor of 39 cm 2 /J is obtained with an optimal average ball size of 22 mm. Referring to Fig. 1 the specific selection function of the smaller size of 0.30 mm (d 50 is compared to the mill feed size distribution) is higher for smaller ball diameters and reaches a maximum value (calculated by the maximum breakage rate relationships) with about 9 mm ball size. Therefore, the grinding with average ball
