  • Patent number: 4261522
    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.

  • Patent number: 4200947
    Abstract: A rotary stripper, which can be chucked to a drive shaft, comprises a pair of discs spaced by a centrally positioned intermediate hub which has radial slots. Immediately outward of the hub and arranged in a ring concentric thereto are a series of equidistantly spaced pins, the axes of which are parallel to the central axis of the hub. The location of the pins, in a circular sense, places one thereof at and in adjacent relation to the outer end of each slot, offset from a direct alignment with the slot. The offset in each case is in a direction counter to that in which the hub is intended to rotate in use.Stripper elements which are relatively rigid but have a minor degree of flexibility are simultaneously slip fit to each pin and in the slot adjacent thereto and are resiliently mounted thereby to the hub. The stripper elements are contained by the discs to either end of the hub.

  • Patent number: 4191338
    Abstract: An infeed disc for a disc refiner has infeed passages which are circularly spaced by portions thereof which define spokes. The spokes and the passages have special characteristics. The center line of each passage is skewed with reference to the axial center line of the disc, in both an axial and a circular sense, and thereby curved, causing the passage to be essentially curved to provide a circular offset of the openings from the respective ends of each passage. The disc is further characterized by a non-radial skewed orientation of its spokes, the center line of each spoke being angularly inclined to a plane which is radial to and includes the central axis of the disc. The centers of the respective axially spaced infeed and operating surface portions of the spokes are offset one from the other, in a circular sense.
