Subsurface mechanical damage correlations after grinding

The grinding of brittle materials can be described microscopically as the removal of workpiece particles created from an ensemble of single or intersecting brittle fractures, which are caused by an ensemble of normally loaded, hard indenters or abrasives sliding or rolling across the surface of the workpiece.

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.
