Abstract[English]
An apparatus (100) and a method (400) for screening a suspension is provided. The apparatus (100) comprises a screen plate (106) with a plurality of screening regions with openings in them. An accept flow of suspension is flowing through the openings to the respective accept spaces. The velocity of the material flow through the openings on the outer screening region (303 a) and the velocity of the material flow through the openings on the inner screening region (303b) are controlled so that the velocity of the material flow through the openings on the outer screening region (303a) is greater than the velocity of the material flow through the openings on the inner screening region (303b).[French]
L'invention concerne un appareil (100) et un procédé (400) de tamisage d'une suspension. L'appareil (100) comprend une plaque de tamisage (106) comportant une pluralité de régions de tamisage avec des ouvertures ménagées dans celles-ci. Un flux d'acceptation de suspension s'écoule à travers les ouvertures vers les espaces d'acceptation respectifs. La vitesse du flux de substance à travers les ouvertures sur la région de tamisage externe (303a) et la vitesse du flux de substance à travers les ouvertures sur la région de tamisage interne (303b) sont commandées de telle sorte que la vitesse du flux de substance à travers les ouvertures sur la région de tamisage externe (303a) soit supérieure à la vitesse du flux de substance à travers les ouvertures sur la région de tamisage interne (303b).
