Ball Mill
A ball mill consists of a hollow cylindrical chamber (Fig. 6.2) which rotates about a horizontal axis, and the chamber is partially filled with small balls made of steel, tungsten carbide, zirconia, agate, alumina, or silicon nitride having diameter generally 10 mm. The inner surface area of the chamber is lined with an abrasion-resistant material like manganese, steel, or rubber.

What Is a Ball Mill? | Blog Posts | OneMonroe
Both ball mills and traditional milling machines are designed to remove material. However, traditional milling machines support large workpieces, whereas ball bills support materials like ore, ceramics and paint. The material is added to the ball mill's compartment, at which point it's exposed to the rotating balls.
