Ball mill Wikipedia. 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 A ball mill
Get PriceBall milling, a shear-force dominant process where the particle size goes on reducing by impact and attrition mainly consists of metallic balls (generally Zirconia (ZrO 2) or steel balls), acting as grinding media and rotating shell to create centrifugal force.In this process, graphite (precursor) was breakdown by randomly striking with grinding media in the rotating shell to create shear and
