AbstractA 40-60 t/h modularized dry coal beneficiation process with a novel method to control the bed was designed around a gas solid fluidized bed separator. Furthermore, the hydrodynamics of medium-solids consisting of wide-size-range magnetite powder (0.3-0.06 mm) and < 1 mm fine coal were numerically studied. The simulation results show that the fluidization performance of the wide-size-range medium-solid bed is good. The separation performance of the modularized system was then investigated in detail using a mixture of < 0.3 mm magnetite powder (mass fraction of 0.3-0.06 mm particles is 91.38 %) and < 1 mm fine coal as solid media. The experimental results show that at separation densities of 1.33 g/cm(3) or 1.61 g/cm(3), 50-6 mm coal can be separated effectively with probable error, E, values of 0.05 g/cm(3) and 0.06 g/cm(3), respectively. This technique is beneficial for saving water resources and for the clean utilization of coal.
