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 …

In ball mills, steel balls or hard pebbles to break particle based on impact and attrition. A rotating mill charged with media and ore is lifted against the inside perimeter. Some of the media falls and impacts the ore particles at the bottom of the mill. The rest of the media cascades and, in the process, creates particle breakage by attrition.

In these applications, the steel ball diameter, throw action, and mill offer a high impact environment. For avoiding excessive breakage, there should exist a balance between the impact resistance and the abrasion resistance. The alloy content and hardness has to be carefully selected based on the milling operations of the customers.
