Since there are many factors affecting the processing capacity of grinding mill, theoretical formula accurately calculating it hasn''t been generated. The processing capacity is usually determined by experience and experiment. The processing capacity of ball mill and rod mill is generally calculated by the volumetric method and power loss method.
Effects of mill feed size and rod charges on grinding
The smaller the rods and the shorter the grinding time, the better the energy utilization. This implies that when using smaller rods for grinding media, processing a coarser mill feed and grinding for shorter times will increase the grinding efficiency. Energy consumption The energy consumption in rod grinding is derived from torque measurement.
Factors Affect Ball Mill Efficiency There are various factors affect ball mill efficiency, such as properties of raw material, feeding size, size and proportion of grinding balls and so on. And these factors are not mutually independent, they all have effect on each other.
Effects of mill feed size and rod charges on grinding
The effects of mill feed size reduction on wet rod grinding has been studied by Strohl : when the percent passing 13 mm in the mill feed was increased from 84% to 98% in rod grinding, the fineness of ground products increased from 85% to 94% passing 0.5 mm, while there was a 10% increase in mill capacity and a 15% decrease in wear of the rods.

The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account.
A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 50% of the mill volume and its size depends on the feed and mill size.
