By comparison, in the Fig. 1b 3roll mill process, the samples are moved from the firstsecond roll to the secondthird roll. Because of the opposite spin directions of each roll, shearing forces are generated in the space between the roll and the rolls. This force allows the sample to mix, milling, and dispersion efficiently [30,31,32,33].

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.
