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 principle of operation of the ball mill, the basic pulverizing device, was already known 150 years earlier; the prototype of the modern mill was invented in the 1870's. Methods of pulverization include crushing, impact, and grinding; compressive strain and shear are very important in these processes.
