Trommels are a rotating sieve often used to sort mineral sands from debris. Here is a DEM simulation of one in action. Note that the mesh is rotating, but the animation frame rate matches the mesh size so it appears stationary. Also note the helix wasn't capped at the inflow end and a few of the small particles go in!
Model run with EPPIC software by Simphysics, and solved on Microsoft Surface Book in 4 hrs.
