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.

A novel approach of evaluating crushing energy in ball ...

The regional total energy in the ball mill under axial segregation is sampled and calculated by the Monte Carlo method. The calculation results show that the distribution of the broken energy in the region is related to the distribution of the ball, and the region with more balls has greater crushing energy, which also means better crushing effect.
