The ball mill abrasion test (BMAT) using a laboratory ball mill appears eminently capable of reproducing alloy performance ratios typical of large industrial ball mills. It is remarkable how closely the quantitative diagnostics from the 300 mm and 600 mm BMAT tests with quartz sand match those from the Climax [16], [24] industrial mills ...

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
