   The present invention relates to a comminution device which works on the principle of crushing comminution, pockets being arranged in a new and progressive manner in the rotor casing.



  Comminution devices, also called “shredders”, where wood materials, plastic materials or cellulose-containing materials are comminuted by the action of knives, the knives being arranged on the jacket of a high-speed rotor located in a housing, are known in the prior art.



  In most of the known designs, the knife holders are welded onto the rotor and the cutting knife is fastened to the knife holder with one or more screws.



  The present invention is based on the object of progressively increasing the exchangeability of the knife holder by virtue of the fact that a faster changeover time, better availability and a usability of high-strength materials. that can no longer be welded to the rotor casing, the possibility of using only a single screw when changing the knife to clamp or loosen a clamping part or the knife, and convertibility to different knife shapes in a short time, depending on the materials to be processed, which is not possible with welded knife holders.



  This bundle of tasks is surprisingly solved with the subject matter of the present invention.



  The comminution device according to the invention is namely characterized in that the rotor casing has at least one pocket in which the knife holder is arranged.

  According to a preferred embodiment, the knife holder is screwed into the pocket. Further preferred embodiments are laid down in further subclaims.



  The essence of the present invention will now be further explained with the aid of the attached FIGS. 1 and 2, which represent preferred embodiments of the invention.



  Figure 1 shows a longitudinal section (broken off) through the rotor casing with a fitted knife holder.



  FIG. 2 shows a cross section (broken off) through the rotor jacket with a fitted knife holder.



  Reference number 1 denotes the knife holder, which is located in the pocket arranged in the rotor jacket 9 and is fixed with the fastening screw 6, which extends through the knife holder into the rotor jacket.



  Reference number 2 denotes the knife, which rests on a base part 5.



  According to a preferred embodiment, a clamping part 3 with a chuck part 4 is provided for fixing, the clamping part 3 working together with a clamping and forcing screw 7 and a lock nut 8 for the forcing process.



  In FIG. 2, the respective elements are identified with the same reference number as in FIG. 1.
