THE EFFECT OF BALL MILL OPERATING PARAMETERS ON
2021-1-6 grinding. Each of these theories was useful in the design and scale up of' ball mill operations, however they told little of the expected size distributions, and most importantly gave no indication of liberation. Later work done by Hukki (1975) attempted to show the validity of each theory within a certain particle size range.
