Abstract
A chamber has upwardly diverging walls so that an upward airstream has different air speeds at different heights in the chamber. When particles such as seeds are put into the chamber, they reach equilibrium at different heights depending on their weights. A horizontal conveyor airstream, much less in magnitude than the upward airstream, directs the classified-by-height particles to a side wall of the chamber, where they are removed.
