In a ball mill circuit, the "output" can be defined as the production rate of fines of the circuit. As for any output, ball mill circuit output is a function of both its inputs and efficiencies. There are two "inputs" to a ball mill circuit: the ore fed to the circuit and the power delivered by the grinding mill.

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.
Planetary Ball Mill. The PM 100 CM operates with a speed ratio of 1:-1 (centrifugal mode). The centrifugal forces pro-duced by the rotation movement the sample and the grinding balls against the inner wall of the grinding jar, where size reduction takes place primarily by pressure and friction.

The Loesche coal grinding mill range is divided into two serial types: Small twin mills constructed to individual specifications (LM 12.2 D to LM 20.2 D), with table diameters from 1,200 to 2,000 mm. Larger mills with two, three and four rollers and modular struc-tures (LM 21.2 D to LM 43.4 D), with table diameters from 2,100 to 4,300 mm.
As the ball wear rate depends directly on the surface of the media charge, a small variation in power will lead to an important increase of wear rate. The risk of underloading or overloading the mill is an additional factor. A direct measurement of the ball level in the mill, more accurate than power readings, as well as a control of it, is
feeding (e.g., making metering into the mill difficult), grind-ing (e.g., plugging the hammer mill screen or blocking the air classifier of a jet mill), and collection (e.g., plugging the bag filters). There are two ways to grind sticky materials. The first solution is to dry the material prior to grinding, or dry and
