Ball mills can be as small as lab-scale mills or as large as industrial mills with a diameter of up to 8 m. The mill's capacity is dictated by its volume. The volume depends on both diameter and length. Generally, the length-to-diameter ratio of the mill, known as the L/D ratio, is between 0.5 and 3.
