Impact energy of particles in ball mills based on DEM ...
There is a linear relationship between specific input power and mill size in log-log scale, which indicates that P i is proportional to D n where n = 2.6 which is within the range reported in the experiments [3,35]. The result suggests that input power obtained from small scale mills can be extrapolated for large scale mills.
