Abstract

In a mounting for the impact strips i.e. beater bars on the rotor of an impact pulverizer or breaker, the strips (4) are fitted into recesses (5) on the rotor shaft (3), said recesses being open outwards as considered radially, the front and rear sides of said strips as considered with respect to the direction of rotation having longitudinal grooves (7, 8) of arcuate cross-section. The strips are held in the recesses (5) by rods (6) connected to the discs (2) and engaging in the longitudinal grooves (7, 8), on one side, while on the other side they are held therein by clamping wedges (9). For the play-free mounting of the strips (4), longitudinal grooves (7, 8) are provided one only on the front side and one only on the rear side, while the rod (6) provided at the rear side of the strip forms an axis of rotation for the strip (4). The clamping wedge (9), which is freely displaceable in the recess (5), engages by a projecting strip (10) in the front longitudinal groove (8). <IMAGE>
