AIR CLASSIFIERS – Van Tongeren

Gravitational Air Classifier: Works by passing a current of air through a curtain of falling material. Fine particulates are swept up in the current of air while the coarse material continues to fall out the bottom of the classifier Used to separate fines less than 150 mesh to 150 microns from more coarse material

Air Classifiers - Prater Industries

2020-5-20  All Prater Air Classifiers separate particles based on the opposing principles of centrifugal force and aerodynamic drag force. As product enters the primary air inlet, individual particles are subjected to aerodynamic drag forces by the conveying air. This drag force varies with the size and density of the individual particles.

2005-2-1  Gravitational–centrifugal air classifiers are two-stage devices having gravitational and centrifugal separation zones, with air circulation in most cases induced by orientable blades. The feed enters the classifier in the air stream into a widening cone , where the coarsest fraction is removed by gravitational separation. The stream with remaining material moves up into the centrifugal zone via

CLASSIFIERS - thermopedia

The rotor has several effects: 1) large particles are deflected back into the classifier, thereby reducing the proportion of coarse particles in the fine product, 2) it aids recirculation of the air stream in some classifier types, and 3) the generation of a forced vortex keeps large particles at the periphery, but fines follow a helical trajectory to the center where they pass out with the exiting air.
