Numerical study on particle mixing in a double-screw ...

15-06-2019  Many issues on the particle mixing and the granular flow pattern remain to be solved in the double-screw conical mixer due to the limited experiment works and no related simulations. In this paper, we quantitatively study the particle mixing in a double-screw conical mixer by DEM with particle number from 0.5 to 1.1 million.

The main flow is driven by the pressure gradient along the channel, while the secondary flow for the mixing is induced by the drag forces of the particles. Here, the particles can move in the flow due to the strong attraction under the periodically-varying magnetic
