Gas-fluidization of nano-particle mixtures in magnetically assisted fluidized bed (MAFB) has been investigated. Nano-particles undergoing fluidization exhibit two types of behavior: agglomerate particulate fluidization (APF) and agglomerate bubbling fluidization (ABF). Fluidization of sole SiO2 or ZnO nano-particles exhibits APF and ABF, respectively, but mixtures of them can be fluidized stably and almost homogenously. Stable fluidization of nano-particle mixtures can be achieved by variations in both the field intensity and the initial mixture content.Simple analytical model is developed to predict the apparent terminal velocity of the mixture of APF and ABF nano-particles, and the calculated values are in agreement with the experimental data.
