Tumbling mills are still the mostly used milling device in the mineral processing industry for both coarse and fine grinding applications. A number of factors affect the performance of tumbling mill. One of these factors is volumetric filling which is the volume of charge in the mill expressed as a fraction of the total volume available.

The sounds emitted from a grinding mill are not random and can be quantified by parameters that quantify noise level, impacting, a steel signal and a rock signal. These can then be used to further describe the manyparticle tumbling mill in terms of steel ball impacts, rock impacts, toe and shoulder angles for both rocks and steel (Figure 2).
In Fig. is shown a large ball mill, designed for the dry grinding of limestone, dolomite, quartz, refractory and similar materials; this type of mill being made in a series of sizes having diameters ranging from about 26 in. to 108 in., with the corresponding lengths of drum ranging from about 15 in. to 55 in.
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.
