According to the ratio of cylinder length (L) to diameter (D), the ball mill can be divided into short cylinder ball mill, L/D ≤ 1; long barrel ball mill, L/D ≥ 1–1.5 or even 2–3; and tube mill, L/D ≥ 3–5. According to the cylinder shape of the ball mill, it can be divided into cylindrical ball mill and cone ball mill.

of the ball mill would be of great interest. Accordingly, the aim of this paper is to identify which dimen-sionless numbers must be kept constant in order to reproduce the results obtained in a laboratory ball mill at the industrial scale. Such scaling criteria are provided by an exhaustive dimensional analysis applied to the ball mill.

A typical type of fine grinder is the ball mill. A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grinds material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.
Industrial ball mills may be used to coarsely crush relatively large pieces of material, whereas lab-grade ball mills are capable of finely milling glass to micron level and below. So-called "high energy" ball milling can even be used to reliably grind the material into nanoscale particles. 4
