    摘要： A blade element pair (20) for a refiner (1, 2, 3) intended for refining fibrous material. Each blade element (5, 5', 8, 8') of the blade element pair (20) comprises a refining surface (6, 9) comprising blade bars (16, 18) and blade grooves (17, 19) extending along the blade element (5, 5', 8, 8'), and openings (14,15) extending through the blade element (5, 5', 8, 8'). The openings (14, 15) in one of the blade elements (5, 5', 8, 8') is at different axial (A) or radial (R) positions from the openings (14,15) in the other blade element (5, 5', 8, 8') when the blade elements (5, 5', 8, 8') of the blade element pair (20) are set substantially opposite to each other.

    摘要： The method is used to grind a suspension of paper fibers (S). Said suspension is ground predominantly as a result of pressure forces between two grinding surfaces (1,2) which are located on grinding tools which are pressed against each other since the grinding tools in the grinding area cannot move or only move very little in relation to each other. The grinding surfaces (1, 2) are porous, enabling part of the water (W) of the suspension of paper fibers (S) to be temporarily received or discharged. A device with a central grinding cylinder (3) and peripherally arranged grinding rollers (4) is particularly suitable as a device for carrying out said method. The grinding surfaces can be embodied as cylinders or provided with toothing.

    摘要： A refiner (1) includes a driving source (20), a rotating shaft (2) rotated by the driving source, a conical-type (3) rotor attached to the rotating shaft, stators (4) disposed in a casing (C) to face the conical-type rotor. The conical-type rotor has a substantially cone-shape first conical portion (31) and a substantially cone-shape second conical portion (32), and bottom portions of the first and second conical portions are joined together. The rotating shaft passes through top portions of the first and second conical portions, and the conical-type rotor is attached to the rotating shaft.

    摘要： The invention relates to a method for compression refining of fibers for papermaking, wherein a slurry of fibers with a consistency of between about 2 wt% and 20 wt% of dry fibers in water is subjected to compression forces in an apparatus comprising at least two rolling surfaces with substantially the same velocity. At least one of the surfaces is curved, such that the surfaces move towards each other to achieve a compression force. The position of smallest distance between the surfaces is a closest position. At least one surface is provided with bars and grooves, the bars being at most 16 mm wide and the grooves being sufficiently large to aid in having water pressed out of the paper slurry. The relative speed of the surfaces to each other is such that water leaves the paper slurry upon reaching the closest position, and wherein the bars compress the fibers.
