Abstract

Procédé de transformation d'une suspension de fibres, destiné en particulier à accroître le rendement d'une installation d'essorage de pâte à papier recyclée, et consistant à traiter les rejets de ladite installation dans un séparateur où le fractionnement se fait dans le liquide et où les fractions provenant du séparateur sont sélectivement introduites dans le courant accepté sortant de l'installation d'essorage. Dans un appareil mettant en pratique ledit procédé un séparateur en liquide (10) est raccordé à l'orifice de rejet (8) de l'installation d'essorage (1) tandis que les orifices d'évacuation des fractions (18, 19, 20) du séparateur sont raccordés à l'orifice de sortie du courant accepté en provenance de l'installation d'essorage (1).
