2020-1-29 size ball mill was used with ball media of sizes 10 mm, 20 mm and 30 mm respectively. Quartz was the material used to perform the experiment and was arranged into 3 mono-sizes namely -8 mm +5.6 mm, -4 mm +2.8 mm and-2 mm +1.4 mm for the experiment. A mill run having a mixture of the 3 ball diameter sizes was also conducted.
