SHREDDER FOR BULKY AND/OR TOUGH MATERIAL

摘要

A machine intended for comminuting objects which are bulky and/or resistant to destruction comprises two shafts bearing comminutor rings disposed alternatingly along each of the shafts. The rings are formed of separate elements, at least some of which are comminutor elements having comminutor noses. The elements each have an inverted-U profile and are secured to the shafts by fitting over shaft-collars integral with the shafts. Journal-and-screw assemblies passing through precision bores in the sidewalls of the elements and in the shaft-collars firmly fix the elements to the shaft-collars, and thus to the shafts. The comminuting machine is very sturdy and withstands very high axial mechanical stresses.
