摘　　要：文章介绍了振动流化床的基本原理,从气泡行为、床层压降、床层空隙率与稳定性以及最小流化速度等方面综述了振动流化床流体力学基础研究所取得的进展;特别综述了振动流化床在物料分离方面的研究,并展望了其在矿物分选方面的应用前景。The principle of a vibrated fluidized bed is presented. The progress in the basic research on hydrodynamics, bubble behavior, pressure drop, ratio of voidage, stability and minimum fluidization velocity of vibrated fluidized bed is reviewed. Especially, the research on material separation using vibrated fluidized beds is also reviewed. The application foreground of vibrated fluidized bed on mineral separation is prospected.
