  • a disadvantage of another type of crushing devices such as in DE 10 2004 031 932 A1 are described, are interruptions due to material accumulation, which occurs in particular when crushing waste with a high green content.
  • the present invention seeks to design a tool for a generic crushing device so that the disadvantages mentioned avoided, but at least substantially reduced.
