Abstract

The side edges (1a, 1b, 1c) of the throwing blade (1) of the disc rotors has a trapezoidal cross-section. These are pushed into radial grooves (2) in the mutually opposite discs of the rotors. The shorter side (1b) of the cross-section trapezium of the blade edge and that (2b) of the corresponding cross-section trapezium of the groove (2) form the blade outer edge and the groove base, respectively. The trapezium of the edge cross-section of the blade is dimensioned such that the chamfered edge (1c) of the blade rear side is at a distance (d) from the groove side edge (2c) opposite it. If the abrasive used has fresh grains which have not been used and have a diameter which is smaller than said distance, then the blade, after releasing the sprung fastening device pressing it cross-sectionally, can be removed in a simple manner and a new blade can be installed in a correspondingly simple manner. <IMAGE>
