The Discrete Element Method (DEM) has emerged as a critical tool in the design and optimisation of grinding mills, offering detailed insights into the dynamics of particle flow and impact within these ...

For steady state transport of particles in a subcritical slab, it is shown that the continuous-space discrete-ordinates approximation converges to the exact solution. This result is established for a ...
