    • A refiner (10, 11) for refining fibrous material comprises at least one first refining surface (1') and at least one second refining surface (2'), which refining surfaces (1', 2') are arranged opposite to one another and mobile in relation to one another. In the refiner (10, 11 ) either at least the first (1') or the second (2') refining surface comprises refining surface portions (15, 27) feeding material to be refined and/or refining surface portions (15, 27) discharging refined material as well as refining surface portions (16) grinding the material to be refined, on the upper surface of which there are blade bars (17) and between them blade grooves (18). Both in the first refining surface (1') and in the second refining surface (2') of the refiner (10, 11) the cross-sectional area (A) of at least some blade grooves (18) is arranged to change in the longitudinal direction of the blade grooves (18). Further a blade element (12) for a refiner (10, 11) intended for refining fibrous material.
    • 用于精制纤维材料的精磨机(10,11)包括至少一个第一精磨表面(1')和至少一个第二精磨表面(2'),所述精炼表面(1',2')彼此相对布置 并相互移动。 在精磨机(10,11)中,至少第一(1')或第二(2')精磨表面包括精磨表面部分(15,27),将精炼和/或精炼表面部分(15,27) )排出精炼材料,以及在其上表面具有叶片杆(17)并且在它们之间的叶片槽(18)上的精炼表面部分(16)上研磨待精炼的材料。 在精磨机(10,11)的第一精炼表面(1')和第二精炼表面(2')中,至少一些叶片槽(18)的横截面面积(A)被布置成在 叶片槽(18)的纵向方向。 还有用于精制纤维材料的用于精磨机(10,11)的刀片元件(12)。
