ABSTRACT:
The invention is directed to a method and system for classifying particulate matter wherein unclassified particulate is projected into a spiraling fluid stream passing through an annular classifying zone. The particulate is projected into the fluid stream from the inner boundary of the classifying zone and the particulate passes through the fluid stream according to the size or density of the particles thereby facilitating the classification of the particles. The fluid stream with the particulate entrained therein is separated into a plurality of annular streams at the end of the classification zone thereby separating the particulate into distinct size fractions.
