Description
709 × 100 × 22 Stator Knife is a precision-ground, stationary cutting component for Virtus Equipment and ZERMA America granulators requiring this specific 709 mm cutting width. The stator knife provides the fixed cutting edge that works in precise scissor-like opposition with the rotating rotor knives to shear plastic material down to the target particle size determined by the screen hole diameter. Accurate cutting gap maintenance between the stator and rotor knives is the single most critical factor in granulator performance — affecting output particle quality, fines generation, power consumption, and knife service life.
