Patent ID: 8262861

Claim:
A refiner plate for a refiner for forming accepts and exhaust from a pulp material, the refiner plate comprising: a refining side extending between inner, outer, and side peripheral walls; and a channel having an inlet passage opening at the refining side and extending transversely through a portion of the refiner plate in the direction away from the refining side, an outlet passage extending from the inlet passage through another portion of the refiner plate in the direction from the inner peripheral wall to the outer peripheral wall, and an outlet located at the outer peripheral wall of the refiner plate and opening to the outlet passage, the refiner plate defining at least one side wall and an inner end wall of the outlet passage; wherein the inner end wall is disposed between the inlet passage of the channel and the inner peripheral wall and defines a blocking surface that physically obstructs accepts entering the inlet passage opening from passing to a pulp feed area of the refiner such that the accepts flow radially outward within the outlet passage to the outlet so as to direct the accepts within the outlet passage away from the refining side of the refiner plate.
