ABSTRACT:
An essentially cylindrical comminuting tool has axially extending cutter bars (8, 8a) having cutting edges (9) at the outer circumference thereof; the cutter bars are located in uniformly distributed position on the circumference of the tool and clamped therein by clamping elements (2, 2a) which are radially moved inwardly, to pull the cutter bars in tightly clamped position, by conical surfaces (18) formed on inwardly projecting portions (16) which engage with conical surfaces formed on clamping disks (19). The clamping disks (19) are drawn together by tension bolts (23). For simple assembly of the cutter bars, two clamping elements (2a) can be joined together into a U-shaped structure (FIG. 4), or all the clamping elements can be assembled in a ring-like structure (FIG. 5). The clamping elements preferably have angled, shallow V-shaped clamping surfaces (5a, 6a) which match similar clamping surfaces (5, 6) on the cutter bars.
