Ball mill rod mill material flow

Flow of materials in rod mills as compared to ball mills . This is partly due to the bridging action of the rods over the coarse particles avoiding the fine sizes (the grinding kinetics aspect), and partly due to the nature of material flow through the mill with its rod load (the material transport aspect)
