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 mill used for carrying out the grinding tests was assembled with 1020 carbon steel, diameter and length equal to 254 mm (10). Tests were conducted at 70% solids and 33% ball load, according to three different ball top sizes, as well as three different mill rotation speeds. Tests included mill shells with lifters and a smooth one.
Oct 20, 2008 The size distribution produced by the ball milling of various crystalline and non-crystalline materials, showed that initially there was a fairly even distribution over the size range up to 355m. However, as milling proceeded two distribution modes developed one at about 90m (the persistent mode) and one at about 250m (the transitory mode).
