The use of DEM coupled with other numerical methods to study ball mills has become a hot research topic (Jonsén et al., 2011, Jonsén et al., 2012, Beinert et al., 2015, Mayank et al., 2015). None of the empirical formulas for computing the power consumption of ball mills considers the effect of lifters (Bond, 1961; Chen Bingchen, 1981).

Ball Milling - an overview | ScienceDirect Topics
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.
