Abstract: With such advantages as low fluidization velocity, wide application range and so on, the vibrated fluidized bed has a further application in coarse particle processing. Due to experimental limitation, its basic theory is not perfect. This paper give a experimental category overview on fluidized bed drop, fluidization velocity, bed uniformity and segregation pattern of monodisperse, binary and polydisperse coarse particle mixtures, give a introduction on CFD simulation study dynamics, and point out its future development trends: the basic theory research on fluidization, mixing and segregation characteristics of actual fluidized bed made of heterogeneous mixtures, especially the stability control mechanism on fluidization flow diagrams, critical conditions of phase transformation.
