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.

Impact mill - Wikipedia

Gravitational impact mills pulverize the material inside a rotating chamber. This is accomplished by a cascading motion of larger pieces repetitively impacting and compressively grinding the product into finer particles as it rotates in the chamber. These are generally referred to as "autogenous" impact mills.
