Weima shredders and granulators are widely used for their robust construction and consistent output in plastics, wood, paper, metal and general waste recycling. KAMADUR enhances this performance by supplying cutting components engineered for demanding industrial environments.

Many facilities that transition to KAMADUR blades experience up to 32% longer operating intervals before sharpening is required. This extended runtime reduces maintenance labor and increases machine availability, especially in high‑volume recycling lines.

We maintain a large inventory of Weima compatible blades in Bleiswijk in the Netherlands, ensuring rapid delivery for all common machine types. Provide your Weima model or part number and we will match the correct cutting components immediately.

KAMADUR Weima knives are produced using advanced CNC machining and carefully controlled heat treatment to achieve precise geometry and long lasting wear resistance. Triple tempering ensures a refined microstructure that maintains sharpness even under heavy loads.

For reinforced or abrasive materials, our carbide‑insert blades deliver exceptional durability. In many recycling plants, carbide options provide up to ten times the lifetime of standard D2 steel, dramatically reducing blade changes and improving overall process efficiency.

These material advantages help Weima machines maintain consistent cutting quality, lower energy consumption and predictable output size.

KAMADUR supplies a complete range of cutting components for Weima shredders and granulators, including:

• Granulator knives for clean and consistent granulate
• Shredder blocks for primary and secondary size reduction
• Knife holders for secure and accurate knife positioning
• Stator blades for single shaft shredders
• Granulator screens for controlled particle size and throughput
• Shredder blades for four shaft systems
• Pre shredder knives for efficient first stage reduction
• Block knives for heavy duty shredding applications
• Sharpening services for straight knives
• Wear and spare parts for continuous recycling performance

We also manufacture custom knives based on drawings or samples, ensuring perfect fit and optimized cutting geometry for specialized Weima applications.

KAMADUR offers Weima rotor and shredder blades in several material options to match your recycling process:

• DIN 1.2379 D2 tool steel for high wear resistance
• DIN 1.7131 alloy steel for balanced strength
• Brazed carbide inserts for extended lifetime
• Solid carbide for extremely abrasive materials

These materials ensure stable cutting performance, predictable output quality and reduced maintenance requirements across all Weima shredding environments.
