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.

Choosing flat end mill vs. a ball end mill will determine the characteristics of the tooling marks (or lack thereof) on your model. Most jobs will benefit from strategic use of multiple size and shape tools for milling different features.

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1– times the shell diameter (Figure ).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

Creative Ball Mill works on the principle of impact on the Feed material and also due to abrasion of one ball over the other and by the free fall of the balls. Due to the rotation of the mill, the mill charge is lifted on the inner periphery of the mill until a position of dynamic equilibrium reached,then it falls down to toe of the mill
