The investigation of the cause of the segregation which arises during barrel finishing is desired, because the workpiece is not mixed with abrasives. Fundamentally, the motion of the workpiece and abrasives is equal to the motion of the discontinuous objects in the rotary barrel. Therefore, if the motion of the particles in the rotary barrel is known, it can be used to investigate the cause of the segregation. In this study, the behavior of the particles in the planetary barrel which rotate about its horizontal axis and revolve around its vertical axis was examined through experiment and analysis using DEM (Discrete Element Method). As a result, it was demonstrated that the segregation was related to the mass ratio and the diameter ratio of two kinds of particles, and that the pattern varied with different combinations of filling particles.
