Variables in Ball Mill Operation Paul O. Abbe®
The starting point for mill speed calculations is the critical speed. Critical speed (CS) is the speed at which the grinding media will centrifuge against the wall of the cylinder. Obviously no milling will occur when the media is pinned against the cylinder so operating speed will be some percentage of the CS.

Dry Grinding  ALPA Powder Technology
Usually, in the machine used for dry grinding, the material will contact and hit other particles or rotors in a closed area until it is broken into the required size. Dry milling can make particles reach micron size. But if you want to achieve smaller nanometer sizes, wet grinding is the only way to achieve this goal.
