Abstract
The invention is directed to a refiner and refiner tooling for economical refining of suspended fibrous material where the radial expanse of the working surfaces (7, 8) deviates from known designs in the following manner: the elevations (10, 11) forming the working surfaces, notably cutters, are several times interrupted, thereby forming grooves (16). It is possible to arrange the shorter cutters (10, 11) on the stator (3) side, on the rotor (2) side, or on both sides. These measures result in a particularly economical and uniform refining.
