  • And more 

What Sets Our Helical Pelletizer Rotors Apart

Advanced Helical Design

Engineered for smooth, consistent cutting action, our helical pelletizer rotors reduce wear and tear on both the rotor and die plate, producing uniform pellets that improve downstream processing and final product quality.

High-Grade Materials & Surface Coatings

Our knives are crafted from wear-resistant tool steels and high-performance metals such as D-2, powdered metals like CPM 10V® and CPM M4®, as well as solid or inlaid Stellite® and ICE™ Inlaid Carbide Extreme.

To further enhance durability and corrosion resistance under extreme conditions, we offer optional coatings including tungsten carbide and zirconia ceramics.

Precision Manufacturing

Our rotors are CNC sharpened to OEM specs with 0.0005″ concentricity and mirror finishes. We offer bolt-in, wedge lock, and solid head rotors, all manufactured to tight tolerances for reliable, repeatable performance. Each rotor can be tailored to your application for maximum efficiency.

What does a helical pelletizer rotor do, and what are its benefits?

A helical pelletizer rotor is a precision cutting tool that slices plastic strands into uniform pellets. Its spiral design delivers smoother cuts, consistent pellet size, and better pellet quality while reducing machine wear. This results in longer service life, less downtime, improved throughput, and lower operating costs.

What types of rotors does Great Lakes manufacture?

We produce rotors in D2, CPM-10V, CPM-M4, and Stainless Steel. For specific applications, we also offer Stellite-tipped, Carbide-tipped, and Solid Carbide rotor knives for superior wear resistance.

How do I know when it’s time to replace my pelletizer rotor?

Signs include uneven pellet size, excess fines, vibration during operation, or difficulty maintaining production rates. If sharpening no longer restores performance, it’s time for a replacement.

How precise are your pelletizer rotors?

Each rotor is CNC manufactured to OEM specs with 0.0005″ concentricity. A mirror finish is available for reliable, long-lasting performance.

Do you offer sharpening or repair services?

Yes. We provide in-house sharpening, MIG weld repairs, and complete refurbishing to extend rotor lifespan and maximize your investment.

Which pelletizer machines are your rotors compatible with?

Our helical rotors fit major brands like Conair®, Rieter®/Automatik®, Ikegai®, and Cumberland®. We also design custom rotors for unique systems.

What is the typical lead time for a new rotor?

Most standard rotors ship within 2–3 weeks. Custom-engineered solutions may take longer, but all production is managed in the USA to keep lead times competitive and reliable.

How much does a helical pelletizer rotor cost?

Pricing depends on size, material choice, and any coatings or customizations. Standard tool steel rotors are more economical, while advanced materials like CPM 10V® or ICE™ Carbide Extreme offer longer life at a higher initial cost but lower cost per run.
