The principle of a turbo air classifier. 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).

Classification in an air classifier is the result of opposing forces in the system. Typically, the classifier comprises a rotating disk that imparts an outward centrifugal force on the particle. Opposing that force is the inwardly moving air flow that provides an inward force on the particle. Both the outward centrifugal force and the …

The structure of the turbo air classifier is shown in Fig. 2.The width and height of the tangential air inlet are 80 mm and 140 mm, respectively. The rotor cage is the core component for separating the coarse and fine particles, and 24 pieces of blades are uniformly arranged along the circumference of the rotor cage.

In a later generation of fluidized bed classifiers the feed is poured onto the grid from above (Fig. 3c, d), so crushing is eliminated [9]. Several prototypes of such fluidized bed classifiers with cylindrical or conical chambers of diameter 350–1700 mm and throughput of 0.5–10 t/h, were constructed for separation of sand, potassium ...

Van Tongeren developed three models of air classifier in 1958, using knowledge of air flow gained through the earlier development of cyclones. The equipment is used to classify particles into different size ranges (as opposed to a cyclone, which is designed to collect particles of all sizes). The three models were the gravitational, the ...

A turbo air classifier schematic diagram is shown in Fig. 1 and positively bowed guide blades are shown in Fig. 2. The powders to be classified are fed through the feed port and fall to the distribution plate. By rapidly rotating the distribution plate, the powders are thrown outward and gravitationally drop into the annular region. ...
