摘要： A refining element for disc refiners, where the refining element on the front side is provided with a pattern of refining members, and a method of manufacturing the same. At least a layer on the front side of the element comprises grains with a size of 0.05-0.8 mm and a hardness exceeding 1000 HV (Vickers), which grains by cold isostatic pressing are included in a matrix of a softer material, such as a steel alloy. The grains constitute 10-15 % by weight. According to the manufacturing method, the grains are mixed with a powder of the softer material, the mixture is placed in a mould and subjected to cold isostatic pressing with a compacting pressure of 2500-7000 bar, whereafter the resulting layer is sintered. This layer can constitute the entire refining segment or at least the front side thereof.

摘要： Method and grinder for the manufacture of fibre pulp from lignocellulosic material, such as wood chips or the like, The fibres are detached from the material by means of a grinding member (6) and the fibrous material is formed into a body, which without rotational movement is fed, while being compressed, into a grinding zone (5) which has converging wall surfaces. In the grinding zone (5) the fibrous material is worked upon by the grinding member (6) which is rotatable relatively to the body of fibrous material and which delimits at least one of the converging wall surfaces of the grinding zone (5). The detached fibres are removed (at 8) from the grinding zone.
摘要翻译：用于从木质纤维素材料如木片等制造纤维纸浆的方法和研磨机通过研磨构件（6）将纤维从材料上分离，并且纤维材料形成为不旋转的主体运动在被压缩的同时进入具有会聚壁表面的研磨区（5）中。在研磨区域（5）中，纤维材料被磨削构件（6）加工，磨削构件（6）可相对于纤维材料体旋转并限定研磨区（5）的至少一个会聚壁表面。分离的纤维从研磨区域去除（在8处）。
