Abstract: Pressurized screen for screening fibrous suspension including housing, and wire basket, having wire openings, inserted in housing to surround wire chamber. Intake chamber is arranged to receive fibrous suspension through intake, accepted-stock chamber, coupled to accepted-stock outlet, is located radially outside of wire basket, and reject outlet is structured and arranged to discharge a portion of suspension rejected at wire basket. Wire scraper, located in wire chamber, has rotor body with scraper elements coupled thereto and drive arranged to run through intake chamber. Rotor body has front surface arranged to face drive, and front surface has rotationally symmetrical projection concentric to rotor body that extends into radially inner end of intake chamber having defined axial extension. Smallest diameter of projection is a maximum of 60% of largest diameter of projection.

Abstract: Pressurized screen and process for screening a fibrous suspension, in which the pressurized screen includes a housing and at least one wire arranged in the housing. The at least one wire has a plurality of openings and a center line of running essentially vertically. A tangential inflow is coupled to an inflow chamber, and an accepted-stock chamber is coupled to an accepted-stock outlet, such that the at least one wire being positioned in a flow path between the inflow chamber and the accepted-stock chamber. At least one reject outlet is provided, as well as a driven wire scraper located in the accepted-stock chamber driven in a circumferential direction opposed to an inflow direction of the suspension through the tangential inflow, and a light-particle outlet coupled to an upper part of the inflow chamber.

Abstract: Pressurized screen for screening a fibrous suspension that includes intake chamber having an intake to guide the fibrous suspension into the intake chamber, and at least one wire element with a plurality of wire openings. The at least one wire element passes at least a portion of the fibrous suspension in the intake chamber and rejects at least a portion of the fibrous suspension in the intake chamber. A centrifuge rotor with apertures is positioned in the intake chamber so that at least a part the fibrous suspension in the intake chamber travels radially inwardly through the apertures and into the at least one wire element. A heavy material outlet removes at least a part of the fibrous suspension not traveling through the apertures. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

Abstract: Hydrocyclone device including at least one hydrocyclone having at least one feeding connector, at least one accepted stock connector, and at least one rejected stock connector. The device also includes at least one distribution and collection device arranged for feeding fluids into and removing fluids from the at least one hydrocyclone, and at least one flange coupled to at least one of the at least one feeding connnector, the at least one accepted stock connector, and the at least one rejected stock connector, which is removably couplable to the at least one distribution and collection device.
