### Flow of materials in rod mills as compared to ball mills

Jan 25, 2012 As mentioned above, the difference in the material flow behavior between the ball mill and the rod mill partially explains the well known difference in the product particle size distribution of ball mills and rod mills. In the case of ball mills, the axial dispersion is higher and the mean residence time is shorter than those in rod mills.
