<p>A sealing ring assembly for use in a pulp refiner unit which includes a housing having a pair of counter-rotating discs and a stock feed inlet mounted to the housing adjacent an opening provided therein for directing raw material toward the discs includes a seal ring defined by a circular flange section detachably mounted on the stock feed inlet within the housing opening and a projecting ring section extending from the flange section toward the discs. The sealing ring assembly also includes an inlet ring defined by a flange section detachably mounted on the disc most adjacent the housing opening and a projecting ring section extending from -the flange section toward the housing opening for concentrically receiving the seal ring's projecting ring section thereby defining an annular clearance region between the projecting ring sections.</p> |
