Ball Milling - an overview | ScienceDirect Topics
Ball milling is a way to exfoliate graphite using lateral force, as opposed to the Scotch Tape or sonication that mainly use normal force. Ball mills, like the three roll machine, are a common occurrence in industry, for the production of fine particles. During the ball milling process, there are two factors that contribute to the exfoliation.

SIZE REDUCTION - Rama University
At low speeds, the ball roll over each other and attrition (rubbing action) will be the predominate mode of action. Thus, in the ball mill, impact or attrition or both are responsible for the size reduction. Advantages: It can produce very fine powder. Ball mill is used for both wet and dry grinding processes.
