    • Abstract
  • Granular materials flow remains an outstanding issue in both nature and industry where typically a range of particle sizes are involved. The mixing and segregation processes of binary granular mixture with particles of identical sizes and with different densities subjected to vertical oscillatory excitation are investigated. The DEM experiments are conducted in the PFC3D, and the material parameters are fixed through the comparison between the numerical and laboratory experiments. Firstly, the deposition patterns of particles in different constraint chutes are studied. Secondly, the kinetic mechanism between uniform particles and mixed particles is compared, and the regular patterns are revealed. Finally, different kinetic mechanisms of the particles in different constraint chutes are studied, and it is proved that the mixed particles under constraint conditions get more kinetic energies and have a longer runout.
