    The Effect of Ball Size Diameter on Milling Performance

    size reduction. The diameter of the balls used in ball mills play a significant role in the improvement and optimization of the efficiency of the mill [4]. The optimum rotation speed of a mill, which is the speed at which optimum size reduction takes place, is determined in terms of the percentage of the critical speed of the mill [8]. The
