Abstract:
A comminution machine comprising a rotor (2) comprising:a plurality of disks (4);a plurality of active wear parts (7);a plurality of inactive wear parts (8) forming a roller-shaped jacket for protecting the rotor (2), each of the plurality of interactive wear parts (8) is detachably connected to one of the plurality of disks (4), the roller-shaped jacket having a plurality of recesses (9) through which the plurality of active wear parts (7) can move, the plurality of recesses (9) are formed between each of the plurality of inactive wear parts (8) and are staggered relative to each other, and wherein(a) each of the plurality of the inactive wear parts (8) are made, at least partially, of abrasion resistant material;(b) each of the plurality of inactive wear parts (8) is formed by a cover face (8.1) and a support (8.2, 8.3); and(c) the roller-shaped jacket is subdivided radially and axially by the cover faces (8.1) so that the cover faces (8.1) are staggered with respect to each other, partially overlap, have different widths, and are notched such as to mesh and to form a jacket surface that provides even and balanced wear properties.
