Horizontal air classifiers with small rotor cage are usually designed for classifying superfine particle. Bauder et al. [12] and Wang et al. [16] studied the effects of the rotor cage shape and the inclined angle of the blade. The experimental results show that a smaller cut size of 10 μm can be obtained by the cylindrical rotor cage, and the ...

Abstract. Volute profile plays an important role in guiding the airflow for a turbo air classifier. The traditional volute design is based on the method of analogue and there is a lack of uniform theoretical design basis and guidance. To meet the needs of guiding the airflow better, a logarithmic spiral volute design method is put forward …

The schematic diagram of a turbo air classifier is shown in Fig. 1. With the pumping action of the air-blower, the negative pressure is formed in the center of the rotor cage, which draws the air flow into the classifier horizontally along two 180° air inlets (7). Then the rotating flow field is formed by air flow guided by guide blades (8 ...
