ABSTRACT:
An air classifier having an upright housing open at both ends in which a pipe section is concentrically located to define a first annular passage closed at its upper end. A feed conduit attached to a pneumatic delivery system is concentrically located within the pipe section defining a second annular passage open at both ends. A cover is mounted over the upper end of the housing defining a dispersing chamber for bulk material. The dispersed material falls through the second passage, beyond the lower end of the pipe into an annular chamber where the components are separated by an air stream moving upwardly. The heavier particles falls and the lighter particle travel with the upward air.
