Air Classification: Computer Models and Experimental Results

Abstract

Computer simulations of the flow fields in centrifugal air classifiers have been undertaken in order to improve both the performance and efficiency of the commercially available Acucut air classifier.A !though the simulations have led to a much greater understanding of the nature of the flow likely to prevail in such systems, accurate predictions have been found to be strongly dependent on the assumption of correct inlet flow conditions during the initiation of the simulations.In spite of the fact that these simulations assumed axial symmetry (which is an oversimplification), they have enabled the identification of a number of engineering modifications which have contributed to reducing the cut size, and increasing the efficiency, of an A cucut Laboratory classifier.
