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 times the drum diameter. Ball mills with a drum length to diameter ratio greater than are referred to as tube mills.

1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.

Ballmills are categorized into four types depending on the motion generated to produce momentum in grinding balls and act upon the material with various milling forces. These are planetary, tumbling, vibratory, and attrition mills. Planetary ball mill. Planetary ball mills are simple and efficient in producing ground/pulverized material.
