摘要： Method and apparatus for refining fiberous material in a disc refiner for withdrawing steam developed during refining of such fiberous material. The disc refinger comprises a pair of refining discs each of which includes a inner refining surface. The refining discs are mounted for rotation relative to one another in a housing with the refining surfaces opposing one another during the relative rotation and defining a refining space therebetween. Each of the refining surfaces of the refining discs is provided with a passageway for withdrawing steam developed in the refining space. The passageways extend from the respective refining surfaces in a direction away from the refining space and radially inward relative to the direction that the fiberous material moves through the refining space.
