Fig. 8 shows the optimum composition of the make-up ball sizes for various feed sizes as a function of the size reduction ratio, R. Because mixtures of two balls (50.8 mm and 25.4 mm ball) are always found to be optimum, the results are plotted with the ordinate being the fraction of 50.8 mm balls.
