Abstract

L'invention concerne un procédé de traitement de pulpe d'une usine de pâte ou de papier. La pâte en question contient des fibres et/ou tout autre composant, tels que des composants minéraux, permettant de disperser les agglomérations dans la pâte. Ce procédé est caractérisé en ce que la pâte est amenée dans un appareil fonctionnant selon le principe d'un broyeur à percussion à double effet (20). Cet appareil comporte un premier rotor (11) pourvu d'aubes, un second rotor (12) pourvu d'aubes et tournant sur le même axe que le premier rotor, dans un sens opposé à celui-ci, ainsi qu'une ouverture d'alimentation (14) s'ouvrant sur les moyeux des rotors. On amène la pâte dans l'ouverture d'alimentation (14) s'ouvrant sur les moyeux des rotors pour la faire passer par les aubes des rotors (11, 12) disposées les unes dans les autres, jusqu'à l'anneau du rotor le plus à l'extérieur, d'où elle est évacuée sous forme de flux de décharge de l'appareil. L'invention concerne également un appareil permettant de réaliser ce procédé.
