Quantitative evaluation of mixing performance of a tumbling fluidized bed granulator with an opposing pulsed jet (PJ) assembly was conducted using an optical sensor and adhesive fine powders. The effects of operating conditions on the degree of mixing were investigated in terms of the ratio of light intensity reflected from the powder mixture to that in the ultimately dispersing state, ηI. The mixing performance was compared to that of other mixers of different types from the viewpoints of the degree of mixing ηI, and the energy consumption during processing. The mixing performance was equal to or higher than that of a high speed stirring mixer. The energy consumption to attain the index ηI of 0.95 using the fluidized bed granulator with the PJ assembly was approximately 50% of that required by the high speed stirring mixer.
