In dry separation, this fluid is generally air. The second class of classifier is based on the particle's ability (or probability) to pass through an aperture, such as a screen. ...

Two main types of centrifugal air classifiers are distinguished by their method of creating air rotation: vortex classifiers and rotor classifiers. Vortex air classifiers use stationary vanes or tangential pipes to rotate the air, creating a centrifugal-counterflow separation zone where fine particles are carried out along a spiral trajectory ...
An air classifier operates on the principle of using air flow to separate fine particles from coarse ones in a mixture. It leverages the differences in particles' aerodynamic properties, such as size, shape, and density. In the process, the mixture is introduced into an air stream, moving at a specific velocity
The air classifier cyclone sorts material by inserting the material into a chamber that has a column of rising air. Air drag on the material supplies an upward force and lifts the material into the air. Since the air drag is dependent on the material's size and shape, the material can be sorted and separated vertically.

1.1 Zigzag air classification. Zigzag air classification is a separation process in which particles are classified mainly according to their falling behaviour in an air flow. Figure l.l.a shows a zigzag air classifier. The channel consists of rectangular sections joined together at an angle ~ to create a zigzag shape.
Air separation systems often require less energy compared to some mechanical separation methods. For example, the energy needed to operate fans and blowers in air classifiers or wind sifters is generally lower than that required for mechanical shredders or grinders. 6. Environmental Benefits
The initial increase in the separation efficiency may be due to the better removal of pea starch granules at higher air-classifier wheel speeds enabling better electrostatic separation. A further increase in air-classifier wheel speed (10,000 rpm) did not remove additional starch granules (Fig. 6 B) and therefore also subsequent …
Most modern classifiers fall under the definition of centrifugal air classifiers, which utilise the opposing forces of centrifugal and drag to achieve a separation. The general theory depicting a single particle within an idealised flow field has been well documented in published literature. The centrifugal air classifier is as follows:
