ball milling
However, when treating materials employing the dry-ball milling process, there are always occurrences of thermodynamic agglomeration of small particles resulting in the reduction of the surface area of the materials and also prevention of uncovering of particles from the mill balls (G. rong Wang, H. ying Yang, Y. yuan Liu, L. lin Tong, and A. Auwalu 2020; Wang et al. 2018).

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.
