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.

The ball mill is used for the grinding of a wide range of materials, including coal, pigments, and felspar for pottery, and it copes with feed up to about 50 mm in size. The efficiency of grinding increases with the holdup in the mill, until the voids between the balls are filled. Further increase in the quantity then lowers the efficiency.

Uneven Wear of the Mill's Lining. Another common cause of disordered steel ball gradation is uneven wear of the mill's lining. If the lining wears unevenly, the steel balls will settle in the lowwear areas, creating an uneven distribution. This is often the result of poor maintenance or the use of lowquality liners.
