摘要： In a screening device, a rotor element on a rotor coaxial with a cylindrical screen drum and a cylindrical screen including: an upper surface and a front face between the surface of the rotor and the upper surface, wherein the front face faces upstream into pulp flow through a gap between the screen drum and the cylindrical screen; a trailing surface extending downstream of the pulp flow from the upper surface, wherein the trailing surface tapers to the surface of the rotor and meets the surface of the rotor at a back region of the trailing surface, and opposite sidewalls extending between the trailing surface and the surface of the rotor, wherein the opposite sidewalls gradually converge towards the back region.

摘要： A separation device having a housing (10) with a feed conduit (1) and a reject conduit (2), between which conduits (1, 2) and an accept conduit (3) of the housing (10) is a rotor unit (13) having a shaft (4) transverse to the through-flow direction of the separation device, which shaft rotates discs (5) attached to the shaft (4), the outer surface and/or side surfaces of which discs are jagged, i.e. they have protrusions (6) and/or notches and/or these surfaces are substantially rough and the teeth (9) of at least two sieves (7, 8) attached to the housing (10), extend between the discs (5), the first sieve (7) being between the reject conduit (2) and the accept conduit (3) and the second sieve (8) being between the feed conduit (1) and the accept conduit (3).
