air classifier particle
A review of process intensification applied to solids handling
Matsubo Corporation in Japan has developed an air classifier that enables simultaneous multiple size classification of fine dry powder. The device is called an "Elbow-Jet Air Classifier" (EJAC), the operation of which is based on the Coanda effect (Fig. 36). The EJAC works on the principle that the trajectory of a particle in an air stream ...

Air classifiers
Gravitational air classifiers. With the use of air flow, gravity and sharp directional changes, the gravitational classifiers perform accurate separations of material from 1,700+ microns down to 150 microns. Coarse particles are conveyed by gravity through a valve at the bottom of the unit, and fine material is conveyed by air to a fabric filter.

In static air classifiers, particles are classified by the air flow along its direction (Knoflicek et al., 2004). Over time, the operational inefficiency of static air classifiers paved the way for developing dynamic air classifiers. Duda (1985) reported that the separation mechanism in a dynamic air classifier is not only due to air flow but ...
