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.
