Abstract

At the defibring/refining of cellulose-containing material, for example in the form of chips, it was found that the design of the refiner members, between which the processing takes place, the so-called refiner disc segments (Fig. 1), is of great importance for the properties of the resulting pulp and the consumption of energy at the processing. A refiner member is a plane disc, in which grooves are provided in such a manner, that between the grooves so-called bars are formed, which conventionally are formed with plane surfaces (10). According to the invention, these bar surfaces (13) have a slightly concave design with a deflection d (Fig. 3).
