270 × 85 × 18 mm rotor knife for Virtus Equipment and ZERMA America GSE/GSC series granulators. Mounted on the rotating rotor, this knife works in precise scissor-like opposition with the stationary stator knives to shear plastic material to the target particle size. Manufactured from D2 tool steel (1.2379) heat-treated to 58–62 HRC for exceptional wear resistance and extended service life. Direct OEM replacement — consult your machine’s parts documentation to confirm correct fitment.
The 270 × 85 × 18 Rotor Knife is a precision-ground rotor cutting component for Virtus Equipment and ZERMA America GSE/GSC series granulators. Mounted directly on the granulator rotor, this knife rotates against the stationary stator knives to create the scissor-like shearing action that reduces plastic parts, production scrap, and recycling material to a consistent, uniform particle size. The 85 × 18 mm cross-section is the standard profile for the GSE/GSC series cutting chamber.

Rotor knives are among the highest-wear components in any granulator — regular inspection and timely replacement are essential to maintaining output quality, minimizing fines, and protecting the cutting chamber from damage caused by worn or chipped knife edges. Always replace the complete set of rotor knives simultaneously to maintain rotor balance and consistent cutting performance across the full rotor face.
