Industrial grinding machines used in the mineral processing industries are mostly of the tumbling mill type. These mills exist in various forms, e.g., ball, rod, pebble autogenous, and semi-autogenous. Balls and rods are the traditionally used media shapes in tumbling mills [6]. Ball mills are typically operated close to their maximum power draw.
