Granulator Rotor Knives | Fly Knives — Precision Blades for Efficient Granulating
Granulator Rotor Knives (also marketed as Fly Knives and Flat Knives) are specialist Cutting Tools designed to deliver consistent particle size reduction in industrial Granulators. This category covers straight-edged Flat Knives and related geometries that are optimised for durability, cutting performance and process reliability. The focus here is on providing technical guidance and clear reasons why the right Rotor Knife improves throughput and Product Quality.
Reliable Performance Where Material Meets Machine
These Components take the primary load in a Granulator: the Rotor Knives rotate on a Cutting Rotor and move against a fixed Stator Knife Block mounted on the chamber rear wall. Under heavy Load, Knife Hardness, Grind Technology and geometrical design determine Stand Time, cutting consistency and the likelihood of unplanned downtime. Manufacturers specify versions for specific Machine Models to ensure exact fit and predictable behaviour.
Why Choosing the Right Knife Directly Impacts Efficiency
Selecting a suitable Rotor Knife reduces wear, minimises production interruptions and improves final Product Quality. Metav Werkzeuge supplies compatible Rotor Knives for more than 30 Machine Manufacturers, including Herbold, Alpine Hosokawa, STF, Condux, Eldan, Neue Herbold, Amis Zerma, Getecha, Wanner and Previero. Performance gains are achieved through targeted Hardening and Precision Grinding, which together increase cutting life and Process Safety while maintaining consistent granulate dimensions.
Practical Benefits You Can Expect Immediately
- High Messgenauigkeit and repeatable particle distribution
- Extended Stand Time through advanced material treatments
- Improved Process Safety due to precise tolerances and fit
- Compatibility with many Machine Manufacturers for fast replacement
- Clear advantages over worn or generic blades in Product Quality
How These Knives Work In Real Applications
When operating, the Rotor Knife shear action against the Stator creates defined chips; Knife Geometry and Clearance control chip size. Different Applications — from recycling plastics to size reduction of technical scrap — require distinct Knife Hardness and edge profiles. Metav Werkzeuge’s Filter System on the product pages helps to locate the exact replacement quickly, reducing selection uncertainty.
Trusted Makers and One Recommended Supplier
Industry-leading brands such as Herbold and Alpine Hosokawa are known for durable machine design, while Metav Werkzeuge stands out as an experienced supplier of precision Rotor Knives tailored to many OEM lines. Their range includes Flat Knives, Long Knives and related Cutting Crowns, each specified for optimal lifecycle in the respective machine.

FAQ
What are the main features of granulator rotor knives | fly knives and how do they improve performance?
Granulator rotor knives | fly knives are precision blades designed for efficient granulating. They include flat knives (also called long knives) with straight cutting edges and are produced using different hardening and grinding technologies to deliver varied wear resistance, process reliability and product quality. Installed on a cutting rotor and working against a stator knife block, they perform the primary cutting action in a granulator, helping to extend tool life and ensure consistent throughput.
How do I find the right rotor knife for my granulator model?
To find the correct rotor knife for your granulator, use the available filters to match dimensions, cutting geometry and material/hardness options. Metav Werkzeuge supplies compatible rotor knives for many machine brands — check the product filters and compatibility lists for Herbold, Alpine Hosokawa, STF, Condux, Eldan, Neue Herbold, Amis Zerma, Getecha, Wanner and Previero, among others.
Do you offer alternatives like cutting crowns, Karo knives or concave knives?
Yes. In addition to flat rotor knives, we offer other rotor knife types such as cutting crowns, Karo knives and concave knives. These are grouped in a dedicated product category—see the cutting crown assortment for those options.
What maintenance practices prolong the life of granulator rotor knives?
Regular inspection for wear, proper alignment with the stator knife block, correct fastening torques and timely regrinding or replacement will prolong the service life. Choosing the right hardness and grind for your application also improves longevity and process stability.
