To obtain the dissipated energy of particles, the motion of the particles and balls was simulated using DEM in a planetary ball mill under dry conditions (Hirosawa et al., 2019).We used an in-house DEM code for the simulation, that is based on the method proposed by Tsuji et al. (1992), and the Hertz-Mindlin contact model was used to estimate the contact force.
