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, during grinding of material. Therefore, it is most disadvantageous to use a ball mill at less than full capacity. Ball mills have the following advantages:

If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or times the drum diameter. Ball mills with a drum length to diameter ratio greater than are referred to as tube mills.
Ball Milling. Cellulose materials were wet ballmilled with a PQN2 planetary ball mill (Livingston, NJ, USA). The enzymatically treated fibers were diluted to wt% and then agitated by a mechanical blender for 10 min. Then 150 g of the diluted fibril slurry were put into an agate jar of 500 mL capacity.
Applications Ball mills are used for grinding materials such as mining ores, coal, pigments, and feldspar for pottery. Grinding can be carried out wet or dry, but the former is performed at low speed.
