  • Grinding in Ball Mills Modeling and Process Control

    Grinding in ball mills is an important technological process applied to reduce the diaphragm or grate discharge mill and centre-periphery discharge mill, e.g. see 23 . In industrial applications, the inner surface of the mill the mill shaft power and the specific gravity of the material. These parameters are thoroughly studied in 4, 5 IV. BALL MILLS Ball mills are one of the more common mills and use a closed cylindrical container that is rotated horizontally on its axis so that the media cascades. A typical ball mill has an L/D ratio of 1.5 1. Ball mills are filled with spheres or other shapes made of steel or ceramics or with pebbles made of flint (or of an ore being ground).
