Impact energy of particles in ball mills based on DEM

Numerical modelling based on DEM has been performed on ball mills of different sizes. It has been shown that the grinding of ball mills of different sizes follows the first-order kinetics. Although different collision environments exist with different sizes of mills, impact energy is a useful index that determines the grinding rate.
