Effect of ball and feed particle size distribution on the
#0183;#32;Mass fraction M3 vs. milling time for various grinding times at a media fill level of J = 20% (a) feed size = 1700 + 850 m (b) feed size = 1 180 + 850 m. Fig. 8 shows that the small 10 mm ball size is superior in generating more material in the fines size class, from both feed sizes used.
