| 英文摘要 | In dry coal beneficiation with air dense medium fluidized bed, the moisture of dense medium would affect the apparent viscosity of fluidized medium, and then change the coal separation performance. In the present work, the apparent viscosity of gas-solid dispersion was measured by using the falling spheres method, and the effect of apparent on fluidization and separation characteristics has been investigated. Results show that the rheology of gas-solid dispersion can be described by Bingham plastic model, and it can be expressed by 渭e=渭+蟿0d0/3vr. As the increase of moisture in the dense medium, the apparent viscosity of gas-solid dispersion increases. This leads to a larger initial fluidization velocity and possible deviation in separation process, in which case the higher separation efficiency cannot be achieved. 漏 2017 PCC.
