Title: Method of operating a disk refiner provided with reversible refining plates

Abstract: A disk refiner is provided with refiner plates having a working surface on each side thereof, and these plates are first mounted with one working surface in face to face engagement with the supporting face of the stator or rotor of the refiner. After the exposed working surfaces of the plates have been substantially worn away by use of the refiner, the plates are temporarily removed, their worn surfaces are ground into substantial parallellism with their unused working surfaces, and they are then replaced in the refiner with their ground surfaces engaging the faces of the stator and rotor.
