Nov 01, 2020· The breakage of a particle in a grinding mill can be accomplished through (1) impact loading, (2) abrading or (3) chipping the particle with a steel ball . These breakage mechanisms mimic either the collinear or non-collinear (eccentric) impact configurations that are defined for analysing the mechanics of two body impacts [4] .

More### Ball mill Wikipedia

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.
