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.
A mathematical analysis of milling mechanics in a planetary ball mill. Earlier, Le Brun et al. [14] have considered the angle of impact in a qualitative manner by classifying the different modes of interaction between the ball and vial wall (i.e. impact and frictional) in terms of (ω v /ω d).The present analysis attempts to examine more thoroughly the role of the angle of incidence (γ) of ...

A ball mill operates by rotating a cylinder with steel or ceramic balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation of the cylinder is typically between 4 to 20 revolutions per minute, depending on the diameter of the mill. The larger the diameter, the slower the rotation.
