PCT No. PCT/SE91/00268 Sec. 371 Date Oct. 13, 1992 Sec. 102(e) Date Oct. 13, 1992 PCT Filed Apr. 25, 1991 PCT Pub. No. WO91/19043 PCT Pub. Date Dec. 12, 1991.A device for screening pulp suspensions includes a cylindric housing (1) with inject inlet (2), reject outlet (3) and accept outlet (4) and screening members in the form of a stator (5) and a rotor (8). The stator (5) as well as the rotor (8) include a plurality of annular elements (6 and 9, respectively), which are arranged in a mutual spaced relationship. The rotor (8) is located radially outside the stator (5), so that the rotor elements (9) are located directly in front of the spaces between the stator elements (6), and the axial length of the rotor elements is greater than the spaces between the stator elements. Thereby gaps (11) are formed between the stator elements and rotor elements. |
