motions in dry mills. In this paper we turn attention to the axial transportation of fine material in a ball mill that is able to discharge from one end. This requires simulation of the entire mill length. DISCRETE ELEMENT METHOD DEM is a particle-based technique. Each particle in the flow is tracked and all collisions between particles and

Nov 01, 2006 This means that axial transport along a dry mill is purely diffusive and is not affected by the three-dimensional details of the actual particle flows. The constant in the error function solution determined by the least squares process is then just a diffusion coefficient D. …

Cleary [80] considered axial transport and grate discharge in a dry ball mill and showed that in the absence of air flow that this is a slow diffusion process. Cleary et al. [81] examined the ...
