Abstract
An air classification system comprises of dual cylindrical chambers mechanically separated, to allow a zone of atmospheric air in between. A primary classification chamber situated vertically below a concentric secondary classification chamber. A rotating parallel blade turbine is situated within the lower primary chamber in order to effect centrifugal particle classification upon a feed material intimately mixed in an air stream. A tubular rotary discharge connected to the turbine which passes through the zone of atmospheric air separating the dual chambers, and extends into the upper secondary chamber which exists to collect and discharge the classified product from the system. A classifier of this design is capable of separating ultra fine particles without stray amounts of oversize with extremely high fine product yields.
