A given mill may operate successfully in more than one class: a hammer mill may be used to prepare a 16-mesh granulation and to mill a crystalline material to a 120-mesh powder. The mills used for size reduction of the granules can be divided into two primary categories based on the energy input into the process.

Here Y represents aggregate output, K the capital input, and N the labor input (capital and labor being the two "factors of production" in this function). The Aterm represents Total Factor Produc-tivity (TFP for short); you can think of this as a "quality" factor—as opposed to K and N which are just quantitative.
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.
