  • Ball Mills an overview ScienceDirect Topics

    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
