DEM simulation and analysis of operating parameters

Different operating parameters such as stirrer rotational speed, slurry solid content and slurry viscosity have an influence on mill performance. Simulation results show that operating the mill at a high impeller speed helps to improve mineral liberation, while at too high impeller speed leads to a waste of electric energy without much
