Attached to the carrier body are suitably shaped working elements 2, 4, 5, 6, 7, 9, 10 and 11, which extend therefrom, and which have working surfaces passing through their respective axes.
  • Working elements 2, 4, 5, 6, 9, 10 and 11, shown respectively in FIGURES 1, 6 through 8, and 11 through 13, are hollow shell-like bodies, all of which have working surfaces constituted by the fiat edge of the working element furthest from the carrier body. All of these working surfaces act on the material to be comminuted.
  • Working element 7, shown in FIGURE 9, illustrates a working element provided with a flat working surface.
  • the working elements 2 are permanently set in carrier body 1, such as by welding or by means of some adhesive.
  • the working elements can be cast with the carrier body as a single unit.
  • FIGURE 4 illustrates an embodiment of the invention wherein the working elements 12 are removably connected to a carrier body 1 by means of screw threads, so that the working elements may be interchanged on a single carrier body to provide different comminuting effects.
  • working elements 2 are set into a carrier body 1 so that they extend through the other side of the carrier body, and an adhesive 14, such as putty, is placed around the extending portion to permanently fix each working element in the carrier body.
  • an adhesive 14, such as putty is placed around the extending portion to permanently fix each working element in the carrier body.
  • a collar 3 is placed around each working element 2, which collar may contain holes through which screws or other fasteners may be placed to secure the working element to the carrier body.
