Title (EN) A REFINER AND A METHOD FOR REFINING PULP
(FR) RAFFINEUR ET PROCÉDÉ DE RAFFINAGE DE PÂTE À PAPIER
Abstract:
(EN) A refiner comprises a rotor (R) arranged rotatable around an axis inside a stator (S) and comprising blades arranged on the circumference of the rotor, opposite the stator, wherein an annular refining space is formed between the rotor and the stator, extending in the axial direction and having a blade clearance between the blades and the inner surface of the stator (S). The feeding means (1) of the refiner are arranged to feed high-consistency pulp to the refining space. The blade clearance is 0.5 to 5 mm, advantageously 1 to 3 mm.
(FR) L'invention concerne un raffineur comprenant un rotor (R) disposé rotatif autour d'un axe à l'intérieur d'un stator (S), et des pales agencées sur la périphérie du rotor opposées au stator. Un espace de raffinage annulaire est formé entre le rotor et le stator, s'étend dans la direction axiale et présente un jeu entre les pales et la surface intérieure du stator (S). Les moyens d'alimentation (1) du raffineur sont agencés pour alimenter l'espace de raffinage en pâte à papier à consistance élevée. Le jeu entre les pales est de 0,5 à 5 mm, et avantageusement de 1 à 3 mm.
