Abstract

In this comminution device, elongated rotor blades (15) which interact with stationary blades (11) are attached in each case to rotor discs (7) arranged with axial spacing from one another. Each rotor blade (15) has a leading cutting edge (5) which moves on a circular rotation path (9), and an outer surface (23) which extends in the direction of the chord with respect to the rotation path (9) between the cutting edge (5) and a trailing edge (17) of the blade (15). The trailing edge (17) lies as closely within the rotation path (9) as is possible without interfering with the rotation of the rotor. An inner surface (31) which is parallel to the outer surface (23) and a trailing surface (27), perpendicular thereto, of each rotor blade (15) rest virtually over their entire extents on carrying surfaces (25) of the rotor discs (7). With this geometry and arrangement, bending stresses of the rotor blades (15) can be kept to a minimum if the rotor blades (15) are dimensioned to have a degree of rigidity which is just sufficient for the loading which occurs. <IMAGE>
