Single Shaft Crown Knife commonly referred to in the industry as a small square knife or moving knife, is the most core wear-and-tear part of a single-shaft shredder. It is fixed to the rotor (main shaft) knife holder with bolts and works in conjunction with the fixed knife on the machine casing to break materials through 'shearing' and 'tearing' actions.
