Abstract
A pressurized disc type refiner having parallel discs housed inside a pressurized chamber and a fluid conveying passageway for removing refined fibrous material entrained in steam is equipped with a second fluid conveying passageway. Fins on the one of the rotating discs impede the entrance of refined fibrous material into the second passageway by centrifugal force so that the steam conveyed in that passageway will be substantially free of entrained fibrous material.
