Abstract
On the basis of the fundamental experiments of the classifying system of many kinds of particles having the axisymmetric collecting unit, the advanced suction unit model of the classifier was constructed, in which the slit nozzle for injection flow is used. In this unit the floating section is newly mounted in addition to the classifying section. The equivalent flow rate of injection and suction can be used to improve the performance and considering the actual system of the classifier. It was found that the effective classification is achieved by mounting the floating section, where the larger particles moves temporally from the fluidized region. The results are compared with the classification curve in the case of the axisymmetric collecting unit.
