Abstract
Waste material classifying apparatus for applying forced air streams to the waste material discharged off the end of a rotary disc screen conveyor, directing the forced air streams into an enclosure at the discharge end of the conveyor, and forming separate passages in the enclosure so that the waste material fractions are classified by the response of the fractions to the forced air or lack of response to forced air streams, whereby the forced air streams tumble and flip the waste material for augmenting the separation of the fractions.
