The feed mate...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 ( Fig. 4c ), where the coarsest fraction is removed by gravitational separation.Air classification of solid particles: a review ScienceDirect

Particulate concentration distribution in centrifugal air classifiers

Abstract. Centrifugal air classifiers are used to separate particles as small as 3 microns from a mixed-size dust. In this paper, the flow in a high-speed classifier is simulated. The 3-d air-phase Reynolds-averaged Navier–Stokes equations are solved in the classifier with two different turbulence closure models.Air Classifier Systems. 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).AIR CLASSIFIERS Van Tongeren

Particulate concentration distribution in centrifugal air classifiers

As particles in the classifier move quasi-statically, the radial equation of motion of an individual particle is: (1) F c + F d = 0 where F c and F d are respectively the centrifugal force produced by the rotation of the particle about the classifier center and the drag force produced by the surrounding (inwards) airflow. From Eq. (1) it is possible to The secondary vortex is eliminated and the airflow becomes uniform in the classifier that belongs to quadrant Π or IV. The experimental results with fluidized catalytic cracking catalysts and fly ash demonstrate that cut sizes of this classifier decrease averagely by 5 μm and 2.2 μm respectively, and the classification accuracy increases by CFD simulation and optimization of the flow field in horizontal

Centrifugal air classifiers can yield differing cut sizes by adjusting the centrifugal acceleration [4]. The MikroCut MC classifier [5] is a typical centrifugal classifier and can separate particles below 10 μm. However, its relatively complicated geometries and high initial cost limit its use in some industrial processes.
