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.

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.
EFFECT OF BALL SIZE DISTRIBUTION ON MILLING. When a ball mill is running at low speed grinding is a result of rubbing action within the ball mass and between the ball mass and the mill liners The size reduction depends mainly on the surface areas of the media in interaction Hukki 1954 This breakage mechanism is known as attrition.
