Impact of ball filling rate and stirrer tip speed on milling iron ore
It was concluded that the particle size distribution (PSD) of grinding products followed well with the Rosin Rammler Benne (RRB) function. In addition, operational parameters such as ball filling rates, stirrer tip speeds and grinding time have been investigated in terms of the width of PSD and specific energy input.

「the distribution of balls in the ball mill」
Abstract The law of ball size distribution in the horizontal planetary ball mill is studied by the discrete element method. The results show that the maximum impact energy could be acquired when filling rate is 24%, moreover the biggest mean contact force and the highest energy utilization ratio of balls could be acquired when the speed ratio is 1.5.
