In this work, segregation of non-spherical particles in gas fluidization is studied by physical experiments. The shapes considered are spheroids with aspect ratio varying from 0.1 to 5.0. It is revealed that binary mixtures of ellipsoids have a higher minimum fluidization velocity than mono-shaped ellipsoids. Segregation occurs in binary-shaped mixtures within a narrow gas velocity range and large shape difference. Initial packing conditions have negligible influence on the final segregation degree.
