Description
The 552 x 85 x 18 Stator Knife is a precision-ground stationary cutting component for the granulator section of Virtus Equipment and ZERMA America shredder granulator combination systems. 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.
