  • Descrição:

    Characteristics of fluidization under mechanical bed vibration for fine cohesive particle have been experimentally investigated. As the vibration intensity increased, the bed flow pattern was changed from the stable gas channels to the bubbling fluidization state coexisted with the frequent gas channel breakage. The propagation of vibration force enhances the dispersion degree of fluidizing gas by breakage of gas channels, and it contributes the formation of bubble and higher bed expansion ratio.
