Abstract
The pressurized screening apparatus for screening fibrous material in liquid suspensions includes a fixed cylindrical screen mounted within a housing to form an inner chamber. An axially extending annular channel receives the suspension. A dilution liquid is passed tangentially into the channel. The dilution liquid helps in the separation of the acceptable fibers from the undesired constituent so that a large proportion of the acceptable fibers is fed through the cylindrical screen and a minimal amount of undesired material flows to the bottom of the annular channel as part of the rejects.
