Abstract (en)

[origin: DE19821447A1] The apparatus to sort fiber suspensions has a main housing (2) with a keyed sieve plate (4) to form a sorting zone (3), and also cylindrical structures for the pulp inlet (5), usable pulp outlet (6) and the outlet (7) for rejected matter. The pulp feed inlet (5) is at a dedicated cover section (8) at the upper side of the housing (2), so that incoming pulp flows at an angle to the horizontal together with combined tangential and axial components at the housing cover section (8). Preferred Features: The angle of the pulp flow and the inlet (5), to the horizontal, is 5 - 85 deg (especially 20 - 45 deg ), including their threshold values. The wall of the housing (2) forms an angled cone towards the outlet (6) for usable pulp. The housing cover section can form an extended entry dish towards the housing or the cover section (8) is a cylindrical entry dish. The housing wall can expand in a cone towards the usable pulp outlet (6) at an angle of 5 deg to the vertical.
