If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.

Ball size. All balls should be the same size. To allow a stable cascade, ball diameter should not be much larger than 20% of the jar diameter. Smaller balls have more surface area and will have more strikes per revolution allowing for faster milling, but each strike has less energy, reducing effectiveness against harder materials. Larger balls ...

To find the suitable ball size for the desired final fineness, usually a factor of approximately 1000 can be applied. If a grind size of 30 µm (D90) is the objective, the most suitable ball size would be between 20 mm and 30 mm. If smaller particles are required, the balls must be removed and replaced by smaller ones for a second process step.
