The diameter of a ball mill has a great influence on the power consumption of the mill and thus on the possible production output. This is because the ratio of the diameter to the grinding path length determines the residence time of the material in the mill and thus the theoretically achievable fineness of the material at the discharge.
Ball Mill
8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

Ball Mill
A pharmaceutical ball mill is a type of grinder used to grind and blend materials while manufacturing various dosage forms. The size reduction is done by impact as the balls drop from near the top of the shell. Ball mills are used primarily for single-stage fine grinding, regrinding, and as the second stage in two-stage grinding circuits.
