Title (EN) SEPARATION DEVICE
(FR) DISPOSITIF DE SÉPARATION
Abstract:
(EN) 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).
(FR) La présente invention porte sur un dispositif de séparation comportant un boîtier (10) avec un conduit d'alimentation (1) et un conduit de rejet (2), entre lesdits conduits (1, 2) et un conduit d'acceptation (3) du boîtier (10) se trouve une unité de rotor (13) ayant un arbre (4) transversal à la direction de passage du dispositif de séparation, lequel arbre fait tourner des disques (5) fixés à l'arbre (4), dont la surface extérieure et/ou les surfaces latérales sont dentelées, c'est-à-dire qu'elles présentent des saillies (6) et/ou des encoches et/ou ces surfaces sont sensiblement rugueuses et les dents (9) d'au moins deux tamis (7, 8) fixés au boîtier (10) s'étendent entre les disques (5), le premier tamis (7) se trouvant entre le conduit de rejet (2) et le conduit d'acceptation (3) et le second tamis (8) se trouvant entre le conduit d'alimentation (1) et le conduit d'acceptation (3).
