ABSTRACT:
The feed and vent apparatus as illustrated comprises a pair of tubes, one constituting an infeed and the other a primary vent tube, joined by an adapter to form an essentially V-shaped structure at the apex of which is an opening from one end of each tube. Material feed means which bridge and substantially fill the cross section of the infeed tube receive the material to be refined from an integrated hopper by way of an opening in the tube which extends a substantial portion of its length. A similar opening in the upper side of the primary vent tube leads to an extension of the escape passage defined thereby the cross section of which is sharply and abruptly expanded. The lowermost portion of the primary vent tube embodies, in a limited portion of its cross section means for receiving and carrying solids attempting to pass through the primary and secondary portions of the escape passage defined by the vent tube and its extension back to the refiner to which the V-shaped structure is connected.
