Abstract (en)
[origin: US2008006580A1] Method and apparatus for removing impurities from a fibrous suspension. The method includes conducting a fibrous suspension stream into an inflow chamber of a pressurized screen, concentrating portions of the fibrous suspension stream to be removed in front of a screen basket, discharging the concentrated portions in an overflow stream, passing an other portion of the fibrous suspension stream through the pressurized screen as a throughput stream, and guiding gases out of a central region of the housing of the pressurized screen. 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.
