Description
The 350 x 100 x 22 Rotor Knife is a precision-ground cutting component for the granulator section of Virtus Equipment and ZERMA America shredder granulator combination systems. 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 350 mm cutting length and robust 100 x 22 mm cross-section profile deliver the structural integrity and cutting coverage required for the high-capacity granulator section of the ZCS 1400 and SG 1400 combination systems.

Key Features
Precision-Ground Profile: Machined to exact dimensional tolerances for proper cutting gap alignment with stator knives, critical for consistent output particle size and minimal fines generation.
Heavy-Duty 100 x 22 mm Cross-Section: Robust profile delivers the structural rigidity required to withstand the high cutting forces of granulating thick-walled plastics, profiles, and production waste.
D2 Tool Steel Construction: Manufactured from premium 1.2379 high-carbon tool steel heat treated to 58 to 62 HRC for outstanding wear resistance, edge retention, and extended service intervals.
50+ Years of Manufacturing Expertise: Produced by a manufacturer with over 50 years of combined steel production and knife manufacturing experience for unmatched consistency and quality.
Replace as a Complete Set: Always replace all rotor knives simultaneously to maintain rotor balance and consistent cutting performance across the full rotor face.
Direct OEM Replacement: Precision machined to original equipment specifications. Consult your machine’s parts documentation to confirm correct fitment before ordering.
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.
All Virtus Equipment Direct knives are manufactured from premium D2 tool steel (DIN 1.2379) with specialized heat treatment to 58 to 62 HRC, delivering outstanding wear and abrasion resistance in continuous industrial granulation environments. Our knives are produced by a manufacturer with over 50 years of combined steel production and knife manufacturing experience, ensuring consistent metallurgical quality and reliable performance across every knife we supply.
Compatibility: ZCS 1400 Shredder Granulator Combination (ZERMA America), SG 1400 Shredder Granulator Combination (Virtus Equipment)
