Distinct Element Method (DEM) has been developed for simulating behavior of discontinuous material by considering interaction between distinct elements,

In the previous paper, we have reported that DEM is useful in simulating particles with various shapes, that is sorted by a Sorting Machine. The purpose of this paper is to discuss designing for an effective chute of a Sorting Machine from DEM results. At first, a repose angle of various types of rice in a stock box was simulated and the simulation results were compared with experimental ones. Secondly, the behavior of rice on a chute of a Sorting Machine was simulated and the simulated behavior was compared with actual one. Finally, we designed an effective chute of a Sorting Machine with DEM.
