An optical sensor and adhesive fine powders were used to quantitatively evaluate the mixing performance of a tumbling fluidized bed granulator with an opposed pulsed jet (PJ) assembly. The effects of operating conditions were investigated in terms of the ratio of light intensity reflected from the powder mixture to that in the ultimately dispersed state, ηI. Mixing performance was then compared with that of other mixer types in terms of mixing degree ηI and processing energy consumption. The granulator's mixing performance was equal to or better than that of a high-speed stirring mixer.† This report was originally printed in J. Soc.
