ABSTRACT:
A rotary disc refiner includes a pair of spaced apart refiner discs for refining or grinding a material that typically is fibrous material such as wood pulp or the like. Pressurized vapor, typically steam, produced as a result of the refining or grinding is exhausted through a channel in the refiner disc which extends through the body of the disc. Preferably, the channel is located in a refiner disc that rotates. The channel includes a vapor inlet opening located preferably in the high pressure midsection of the refiner disc, a vapor outlet opening which discharges the steam to the relatively low pressure outer section of the disc, and a passageway behind the refining or grinding surface of the refiner disc connecting the inlet to the outlet.
