Abstract: The gas-solid fluidisation separation of coal-series kaolinite has wide feed size, and the fluidisation characteristics of different particle size are different. The Computational Fluid Dynamics (CFD) and Discrete Element (DEM) coupling technology are proposed. Simulation results show that the pressure and kinetic energy characteristic in the separation area are conducive; the clear movement track mechanism of heavy products and light products of coarse particle size (50-75 mm), middle particle size (25-50 mm) and fine particle size (13-25 mm) are discussed respectively; also, the collection efficiency with different particle size are theoretically studied. It is found that the experimental yield has less error with the theoretical value of 2.5 g/cm³ heavy products, and the distribution state of the final heavy products is consistent with the actual separation.
