In this work the grinding media motion inside a vertical stirred mill was investigated using the Discrete Element Method (DEM) and the results were qualitatively compared against similar conditions from published literature. Two impeller designs having different arm length were investigated as function of low and high rotational speeds (50 rpm and 250 rpm). A coarse graining (CG) tool was
