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 ...
Air classifiers work by combining the principles of centrifugal and drag force, collision and gravity to generate a balanced, high precision method of classifying particles according to size and density. While density does play a role in air classifier separation, the internal air currents are mostly affected by the overall mass and weight of ...

Gravitational inertial air classifiers use a primary and a recirculating secondary airflow to separate fines from coarse particles. Because the airflows are not affected by wear, the grading remains consistent to an accuracy of microns. At the same time, particle moisture remains at an optimal level. Different fractions ranging from 300 μm to ...

A typical air classifier mill — called a verti-cal air classifier millbecause of its classifier wheel's ori-entation — is shown in Figure 1. The mill has a round vertical housing enclosing an internal classifier wheel, which has multiple closely spaced vanes (or blades), and an impact rotor that's mounted in a horizontal position and
