Abstract
An ejection hood apparatus includes a transfer conduit and a hood. The transfer conduit includes a downwardly concave control shell. An inlet end portion of the transfer conduit receives an upwardly directed transfer air stream including ejected material with at least a partially upward trajectory. The hood defines an ejection chamber including a lower chamber portion and an upper chamber portion. The lower chamber portion receives the transfer air stream from an outlet end portion of the transfer conduit with at least a partially downward trajectory. The hood includes at least one air outlet passage communicated with the upper chamber portion for exhausting at least a portion of the transfer air stream.
