    摘要： 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 (α) of the blade bars being arranged so as to provide pumping blade bars, and their blade bar angle (α) being greater than the blade bar angle (α) 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 (α) 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.

    摘要： A refiner (1) comprising a stator (2) and a rotor (4). The stator (2) and the rotor (4) comprise a flat portion (7, 9) and a conical portion (8, 10). The conical portion has a first end (17) of smaller diameter (D1) and a second end (18) of greater diameter (D2) such that the first end is directed towards the flat portion and the second end is directed away from the flat portion. The refining surface (12) of the conical portion of the stator comprises at least an outer zone (23) arranged at the second end of the conical portion and an inner zone (22) arranged relative to the outer zone on the side of the first end of the conical portion. A portion of the length of the blade bars (20) in the outer zone are arranged relative to the rotation direction (RD) of the rotor such that they have a retentive effect on the material to be refined. Also a blade segment (19) for a conical portion of a stator of a refiner.
