Rotary shredder for metal contg. material - has blades fixed to moving and stationary to define negative cutting angle between them

摘要

Blades are fixed to the stationery (3) (13) and moving parts (10) and these have a negative cutting angle of roughly 15 deg. On the lower part of the body is a perforated sheet to separate shredded from unshredded material. A number of square blades are fixed on the periphery of the turning part and on one or more lines of the upper part of the body. The blades are securely nipped by a fixing end in a housing forming an angle holding them firmer when working.
