Abstract

A cutter segment for a disc grinder or the like, said grinder consisting of two oppositely placed cutters made up of several segments attached to each other, at least one of the cutters being rotable, said cutter segments being provided with a rough surface or with teeth (5) and grooves (6) for the grinding of material such as wood chips. With prior-art grinders of this kind, exhaustion of the steam produced in the grinding process has proved to be a difficult problem. The cutter segment of the invention solves this problem in that the segments of at least one of the cutters are provided with one or more exhaust channels (7) having a sectional area essentially larger than that of the grooves (6).
