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.

The high energy of these mills is derived from the very high rotation speeds that are achievable. For example, Salimon et al. used their planetary ball mill at a rotation speed of 1235 rpm corresponding to the mill energy intensity of 50 W/g. It has been reported that some of these mills can be used at rotation speeds greater than 2000 rpm.

High Energy Ball Mill. Ball Mill is a grinder that blends or grinds materials for various applications. Impact force enables size reduction in feed material. The cylindrical shell rotates around its horizontal axis. The main element enabling grinding is the hard and small balls in the ball mill. These balls are usually made of steel.
