Abstract: front page image
(EN)A refiner (1) comprising a stator (2) and a rotor (6) that comprise a planar portion and a conical portion after the planar portion, which in turn comprise refining surfaces (4, 8) provided with blade bars (15, 18, 24) and blade grooves (16, 19, 25) therebetween, and the planar portions (4’, 81) of the refining surfaces (4, 8) of the stator (2) and the rotor (6) comprising at least two refining zones (14, 17, 23) in the direction of the radius (R) of the planar portion. At least the planar portion (8’) of the refining surface (8) of the rotor (6) is provided with blade bars (18) in its outermost refining zone (17) in the direction of the radius (R), the blade bar angle (&agr;) of the blade bars being arranged so as to provide pumping blade bars, and their blade bar angle (&agr;) being greater than the blade bar angle (&agr;) of the blade bars (15, 24) in the previous refining zone (14, 24) in the direction of the radius (R) of the planar portion (8') and that the blade bar angle (&agr;) is 5 - 50 degrees so that the blade bars (18) in the outermost refining zone (17) have an overall pumping effect on the material to be refined.
(FR)Raffineur (1) comportant un stator (2) et un rotor (6) qui comprennent une partie plane et une partie conique après la partie plane, celles-ci comportant elles-mêmes des surfaces (4, 8) de raffinage pourvues de barreaux (15, 18, 24) de lames et de rainures (16, 19, 25) de lames entre ceux-ci, et les parties planes (4’, 81) des surfaces (4, 8) de raffinage du stator (2) et du rotor (6) comportant au moins deux zones (14, 17, 23) de raffinage dans la direction du rayon (R) de la partie plane. Au moins la partie plane (8’) de la surface (8) de raffinage du rotor (6) est pourvue de barreaux (18) de lames dans sa zone (17) de raffinage la plus extérieure dans la direction du rayon (R), l'angle (&agr;) des barreaux de lames étant prévu de façon à donner des barreaux de lames à effet de pompage, leur angle (&agr;) de barreaux de lames étant supérieur à l'angle (&agr;) des barreaux (15, 24) de lames situés dans la zone (14, 24) de raffinage précédente dans la direction du rayon (R) de la partie plane (8'), et l'angle (&agr;) des barreaux de lames étant de 5 à 50 degrés de telle sorte que les barreaux (18) de lames dans la zone (17) de raffinage la plus extérieure aient un effet global de pompage sur le matériau à raffiner.
