Herbold Granulator Rotor Knife

Durable Herbold granulator rotor knife

Herbold granulators are commonly used in the plastic recycling industry to reduce the size of plastic waste into smaller granules for further processing. Fernite offers a complete range of rotor and static knives that are compatible with Herbold Granulators.

Regarding the rotor knife in a Herbold granulator, it is a crucial component responsible for cutting and shredding the plastic material. The design and specifications of the rotor knife can vary depending on the specific model of the granulator and the type of plastic being processed


These knives are built to last and are made with the latest CNC technology. They can be used in the toughest conditions, making them an ideal choice for many plastics and rubber processing plants worldwide.

At Fernite, we understand the importance of continuous operation for Herbold granulators, and that’s why we have optimized the design of our granulator knives for cutting challenging materials. The geometry and arrangement of the knives on the rotor also play a significant role in the efficiency of the granulation process.
