A laboratory 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.
Advantages of this ball grinding mill include: less friction, less energy and more easily activated, because large diameter double row self-aligning roller bearing instead of sliding bearing is used as the main bearing. this ball grinding mill can achieve bigger capacity thanks to larger size of feed.
