With increasing speed of the ball mill from 200 to 400 rpm at a fixed milling time of 30 h, the particle size of the milled powders decreases gradually till it reaches a saturation value. This observed result agrees with a mathematical model that describes the dependence of post-milling particle size on the rpm of a mill.
size, feed particle size distribution, fraction of mill filled with balls and powder, mill diameter, mill speed and other variables affecting them. Load behaviour as an additional mill control parameter is an important aspect because of the relation between the variation of mill power with operating parameters …
For each grain size there is an optimal ball size (Trumic et. al., 2007). The bigger ball in relation to the optimal one will have an excess energy, and consequently, the smaller ball mill has less energy necessary for grinding.

The TM 300 XL Drum Mill is used for the preparation of granules and powders. The grinding process is performed either in dry or wet conditions. The drum mill can be operated either as a Ball or as a Rod Mill by using the corresponding module. A sufficient number of balls or rods is required for an effective grinding process.
However, these parameters are sensitive to milling conditions such as the mill rotational speed, ball filling, powder filling, mill diameter, and ball diameter. Therefore, they must be appropriately corrected in order to be used for large-scale industrial mills operating under different conditions.
The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 and maximum and finally the type of circuit open/closed ...

Ball milling - A device used to reduce the particle size of materials, bodies or glazes. A ball mill is simply a container that is filled with pebbles (either of porcelain or stones e.g. Flint) into which a charge (powder or slurry) is put and that is then mechanically rotated to cause the tumbling pebbles to crush particles that happen between them.
