A feature of ball mills is their high specific energy consumption. A mill filled with balls, working idle, consumes approximately as much energy as at fullscale capacity, that is, during the grinding of material. Therefore, it is most disadvantageous to use a ball mill at less than full capacity.

Overview of Ball Mill. Ball mill, also known as tumbling or pebble mill is milling equipment that encompasses cylindercontaining balls and is mounted on a metallic frame that can be rotated along with a longitudinal axis. The large ball tends to break down coarse feed materials and the small ball mill to form fine products by reducing void spaces.
