The influence of the dispersion level of fine powder on the efficiency of classification was studied using a cyclone air classifier and several dispersing orifices. Agglomerated fine powder was dispersed by a high-speed air stream through an orifice, and the dispersed particles were classified by a cyclone air classifier. The range of orifice diameter was 630 mmΦ and that of air velocity was 10230 m/sec.
By using a dispersing orifice before the classifier, the yield of fine particles was increased. The higher the air velocity, the higher was the yield. It was concluded that the high-speed air stream through an orifice disperses agglomerated particles and improves the classification efficiency.
