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.

One Of The Critical Steps In The Bayer Process Is

One of the critical steps in the Bayer Process is the digestion of crushed bauxite ore, which contains alumina in a solid mixture with other oxides such as silica (SiO2) and titania (TiO2). This reaction involves steam and a solid liquid mixture (called a slurry) of concentrated NaOH and crushed bauxite.
