Abstract

L’invention concerne une installation destinée à séparer les composants d’un mélange contenant des fibres 2) et des granules (3), ladite installation comprenant un tribochargeur (4) pour conférer aux composants (2, 3) une charge électrostatique, au moins une paire d’électrodes (5, 6) pour générer un champ électrique séparateur qui achemine les composants chargés, selon leur polarité, jusqu’à des collecteurs (10, 11), ladite installation étant caractérisée en ce que le tribochargeur (4) possède une grille (14) de confinement agencée pour retenir les composants dans le tribochargeur (4) jusqu’à ce que lesdits composants (2, 3) aient atteint une charge suffisante, puis pour laisser passer lesdits composants, une fois chargés, dans l’entrefer (7) d’où lesdits composants (2, 3) gagnent leur collecteur (10, 11), sous l’action du champ électrique séparateur. Figure 6The invention relates to an installation for separating the components of a mixture containing fibers 2) and granules (3), said installation comprising a tribocharger (4) for giving the components (2, 3) an electrostatic charge, at least a pair of electrodes (5, 6) for generating a separating electric field which routes the charged components, according to their polarity, to collectors (10, 11), said installation being characterized in that the tribocharger (4) has a containment grid (14) arranged to retain the components in the tribocharger (4) until said components (2, 3) have reached a sufficient charge, then to allow said components to pass, once loaded, into the air gap (7) from which said components (2, 3) reach their collector (10, 11), under the action of the separating electric field.
