Abstract

La présente invention concerne un dispositif servant à séparer les impuretés légères des suspensions de pâte à papier. Le dispositif (11) est destiné à être relié à l'enveloppe (1) d'un appareil de fractionnement dans lequel la structure fibreuse est brisée et la pâte est mise en rotation pour enrichir les impuretés légères. Le dispositif de tamisage (11) est réalisé avec une enveloppe symétrique en rotation (13, 14) destinée à être reliée de façon centrale, par un passage (12), à la partie supérieure de l'enveloppe (1). Une arrivée (15) du liquide de dilution est reliée tangentiellement à l'enveloppe (13, 14) et une sortie (16), pour les impuretés légères, a une position centrale au sommet de l'enveloppe (13, 14).
