AXIAL TRANSPORT IN DRY BALL MILLS CSIRO CFD

The ball mill is initially uniformly filled with rocks and balls which are perfectly mixed. Figure 3 shows the charge in the mill after 4 minutes of rotation (at 75% critical). The charge has been clipped by a vertical plane passing down through the center of the mill so that the internal distribution of particles can be seen. In the upper
