Plastics Granulator Rotor
Rotors hold the rotating knives that drive material into the cutting zone between the rotating and mating stationary knives mounted on the granulator bed. The four main types of rotors are open, closed or solid, staggered, and staggered/segmented. Open rotors are good for granulating heat-sensitive resins or feedstocks that are still warm from processing. Closed or solid rotors provide a much stronger knife mounting arrangement to cut through the thickest feedstocks. Staggered rotors are excellent for cutting most heavy, thick-walled parts.
