Abstract

L'invention concerne un procédé d'utilisation de déchets de papier récupérés. Les fractions contenant des fibres courtes sont d'abord séparées des fractions contenant des fibres longues, les fractions contenant des fibres longues étant régénérées dans un broyeur 10 et, ensuite, au moins une partie de la fraction contenant des fibres courtes et précédemment séparée dans un appareil de fractionnement étant ajoutée à la fraction de fibres longues régénérées en vue d'un traitement ultérieur. Application à l'industrie du papier.A method of using recovered waste paper is disclosed. The fractions containing short fibers are first separated from the fractions containing long fibers, the fractions containing long fibers being regenerated in a mill and, then, at least part of the fraction containing short fibers and previously separated in a mill. fractionator being added to the regenerated long fiber fraction for further processing. Application to the paper industry.
