In the field of surface treatment, barrel polishing is an extremely efficient processing method for the surface smoothing treatment of a large number of workpieces. However, workpieces and grinding materials may separate depending on the conditions. In this study, two kinds of particles of different materials and sizes were filled into the planetary barrel that simultasneously rotates around the horizontal axis and revolves around the vertical axis, and the behavior of these particles was examind through experiments and simulations using the discrete element method (DEM). The rotary barrel with the cross section of a regular polygon was used. As a result, it was demonstrated that the distribution of two kinds of particles in segregation might be inverted by the difference between the cross-sectional shape of the rotary barrel, even if the same combination of two kinds of particles was filled.
