As in ball mills, the power draft of a rod mill is the product of capacity and work index, which is the energy required to break a mineral of a given size to the required size. The mill power is also increased by increasing the rod charge and the mill speed, while the mill power and capacity are both increased with increasing mill length.

The vibrating ball mill also works on the principle of attrition and impact. It consists of a mill shell containing a charge of balls similar to that of ball mills. In this case, the shell vibrates due to some frequency rather than rotated. Uses (i) Small capacity ball mills are used for the final grinding of drugs or for grinding suspensions.

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.

Its job, to grind rock by tumbling it in a large metal cylinder loaded with steel balls, is highly energy intensive. In fact, the cost of grinding in a mining operation represents a significant proportion of the total energy cost. One way of fully utilising the capacity of a ball mill is to convert it from an overflow to a grate discharge.
