The importance of particle density in passive pulsing air classifiers is examined. It had heretofore been assumed that passive pulsing classifiers separate particles according to density, although the assumption had never been tested. Theoretically, pulsing isolates the segment of the particle velocity curve where a denser particle falls faster than a less …

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).
