Abstract

La présente invention se rapporte à un raffineur servant à raffiner de la matière telle que des copeaux de bois ou similaires, qui comprend : des premier et second rotors opposés et pouvant tourner l’un par rapport à l’autre (11, 12), qui sont dotés d’éléments de raffinage (15, 16) et qui délimitent entre eux un espace de raffinage avec une zone de raffinage (17) pour le traitement de la matière. Le premier rotor (11) comprend des ouvertures (19) ayant un côté entrée et un côté sortie (19a, 19b) conçus pour le passage de la matière, le côté sortie étant adjacent à la zone d’alimentation (18) de l’espace de raffinage ; une chambre d’alimentation (22) vers laquelle doit être acheminée la matière, et qui est adjacente au côté entrée des ouvertures (19) du rotor ; un dispositif d’alimentation coaxial (23) comportant un corps de vis (24) et des filetages en forme d’hélice (25), ledit dispositif d’alimentation coaxial (23) étant placé à l’intérieur de la chambre d’alimentation (22) afin de tourner en même temps que le premier rotor (11) et de porter la matière vers les ouvertures (19) du rotor. Les filetages (25) du dispositif d’alimentation coaxial (23) comprennent une partie essentiellement droite (25a) qui s’étend essentiellement depuis le corps de vis (24) et qui, en fonctionnement, est destinée à porter la matière dans la direction longitudinale vers l’espace de raffinage, la partie droite (25a) passe dans une partie supérieure (25b) qui est destinée à limiter le mouvement radial de la matière.
