    Materials Science. The Ball Mill Abrasion (BMA) test was developed by the University of Queensland Materials Performance group to simulate the high stress abrasion conditions experienced in production ball mills. It gives accurate predictions of the service life of wear resistant alloys in mill liner and grinding media applications.Grinding Balls and Other Grinding Media: Key consumables,2021-1-25 · Tower Mills: 0.5”-1.5” grinding balls are recommended. The normal top size of media used is 10-25mm, but even smaller grinding balls can be used for very fine grinding. Isa Mills: <0.1” grinding balls are recommended. The Isa Mill is more efficient when using small media (i.e. high-chrome steel balls).
