KAMADUR supplies high‑quality blades and wear parts for Herbold grinders, granulators and shredders used in plastics recycling and size reduction.

With more than 25 years of experience in Herbold equipment, we deliver cutting solutions that ensure reliable performance, long service life and consistent output quality.

Just tell us which Herbold machine is in your plant: we supply the correct parts every time.

Our Herbold blades are produced from high‑quality 1.2379 / D2 tool steel, CNC‑machined and heat‑treated in advanced furnaces for optimal microstructure.

Triple tempering ensures excellent wear resistance, toughness and strength for continuous operation in demanding recycling environments.

For abrasive materials, we offer TC inlay blades with up to 10× longer lifetime between sharpenings compared to standard 1.2379 / D2.

• Granulator knives: Rotor and stator knives engineered for stable cutting geometry and consistent granulate size.
• Granulator screens: OEM‑dimension screens for correct particle size control and predictable throughput.
• Guillotine knives: High‑strength knives for pre‑cutting bales, sheets and bulky feedstock.
• Wear & spare parts: Deflector blades, shredder blocks, spacers, seals and other wear components.
• Sharpening straight knives: Professional sharpening to restore cutting quality and reduce energy consumption.
• Pulverizers: Wear parts and replacement components for Herbold pulverizing systems.
