A comparative analysis of steel and alumina balls in fine milling …
The ball motion in the mill was simulated via discrete element method (DEM). Our results show that steel balls achieved faster breakage of clinker into finer particles than alumina balls, which was explained by the higher total–mean energy dissipation rates of the steel balls. The PSD became finer as smaller balls were used.
