Abstract

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.
