Recirculation rate in the spiral passage of Spray Granulator-Dryer was studied
and the mechanism of thes liding of particles into the spiral passage was inrestigated.Model for the calculation of recirculation rate was established.The recirculation rate was equal to the average volume of particles passing into the spiral passage inlet per unit time times an effective “recirculation coefficient”.The parameters controlling the effective recirculation coefficient and the influence of holdup coefficient were discussed.
