摘要： A pair of opposed co-operating refining elements (1, 2) intended for a disc refiner for the disintegration and refining of lignocellulosic material in a refining gap between two opposed counter-rotating refining discs. The refining elements are intended to be placed directly in front of each other on opposed refining discs, and both refining elements (1, 2) are formed with refining surfaces with bars (3, 4) and grooves (5, 6). In order to prevent generated steam from flowing rearward in the refining gap, a first refining element (1), which is intended for a rotary refining disc, is formed with a first radially restricted zone (7) with elevated bars (8) and a second radially restricted zone (9) without bars directly outside the first zone (7). A second opposed refining element (2) is formed with a third radially restricted zone (10) without bars, which third zone (10) is located directly in front of the first and the second zone (7, 9) on the first refining element (1).

摘要： A refining element intended for refiners for the working of fibrous material, where the refining element (10) is formed with a pattern of bars (11) with upper surfaces (13) and side surfaces (14) and intermediate grooves (12). The bars (11) extend arc-shaped outward over the refining element and the upper working surfaces (13) of the bars (11) are wider and provided with a plurality of smaller grooves (18), which form angles within 10-90 ° with the longitudinal direction of the bars, so that the smaller grooves (18) on the bars (11) extend substantially radially.

摘要： Refining element intended for a refiner with flat or conical opposed refining surfaces, which are rotary relative to each other for working and refining lignocellulosic material during its passage through a refiner gap (15, 35) between the opposed refining surfaces from an inlet portion with smaller diameter to an outlet portion with greater diameter. The refining element (19, 39) is formed with a refining surface with bars (20) and intermediate grooves (21) which extend over the entire refining element. The bars (20) in the inlet portion of the refining element (19) form an angle of 50-85 DEG with the radius or generatrix of the refining surface. The angle decreases along the surface of the refining element (19, 39) so that the bars (20) in the outlet portion form an angle between -25 DEG and +25 DEG with the radius or generatrix. The bars (20) in the inlet portion are located at a greater mutual distance than in the outlet portion.

摘要： A refining element for a disk refiner, which element is provided on its front side with working members (2) and is formed with through holes (4) for its attachment on a holder in the refiner. The refining element (1) further is provided with at least one centrally located threaded hole (5), which in operation is covered from the front side by a covering screw (7). At the exchange of refining elements, the threaded hole (5) is intended for a longer screw, by means of which the element (1) can be removed from the holder.

摘要： The invention relates to a method of manufacturing fibre pulp from lignocellulose-containing material, where the material is disintegrated between two grinding discs rotating relative to each other. According to the invention, the material is defibered and fibrillated by a shear-like effect between opposed bars in the two grinding discs, in that the angle (a) between the bar edges and the radius (M) of the segment in the two grinding discs is between 5° and 30°, preferably between 7.5° and 22.5°.
