    This paper compares the performance of a 25/75 pebble/ball (volume ratio) composite charge to ballmilling, under conditions typical for a ballmill in SABC circuits, i.e. a large ball.Ball size distribution for the maximum production of a ,Abstract Ball size distribution is commonly used to optimise and control the quality of the mill product. A simulation model combining milling circuit and ball size distribution was used to determine the best makeup ball charge. The objective function was to find the ball mix that guarantees maximum production of the floatable size range (i.e. − 75 + 9 μm) applicable to a Calculate and Select Ball Mill Ball Size for ,201382 Based on his work, this formula can be derived for ball diameter sizing and selection: Dm <= 6 (log dk) * d^0.5 where D m = the diameter of the singlesized balls in mm.d = the diameter of the largest chunks of ore in the mill feed
