Granulator rotor knives / fly knives

Granulator rotor knives (also known as fly knives) are crucial components in granulators used for size reduction in various industrial processes. They are designed to shred, cut, or granulate materials into smaller, uniform pieces , as for example (PET, plastic, copper, aluminium, rubber, etc.)

Granulator knives

SIKNIVES for granulation of synthetic, plastic, and other waste materials are produced from the best quality steels (standard, bimetal-Duralife, tungsten carbide, etc.) and are available in various steels and hardnesses. They are custom-manufactured for your specific requirements and waste materials thus improving the durability of the knives, optimizing machine performance and lowering knife costs. Our heat treatment processes and hardening techniques have been perfected through 50 years of experience to enhance the strength and durability of granulating blades.

Products made by SIJ Ravne Systems are our own perfectly fitting, process-optimized SIKNIVES brands and are not original equipment manufacturer parts (OEM) by the machine manufacturer.

Knives from our production can be installed in granulating and extruder machines, produced by manufacturers, such as: Herbold, Zerma, Previero, Tria, Cumberland, Guidetti, Folcieri, Profing, Wanner, Piovan, Getecha, Erema and others.
