Powerful Shredder Cutters for Reliable Recycling Performance

Shredder Cutters | Concave Cutters are specialist Cutter Heads engineered to improve Shredding Performance and uptime in single-shaft Shredders. These Concave Cutters deliver an aggressive Cut Profile for Plastics, Wood and Mixed Waste while remaining compatible with a wide range of Machine Brands. The Range includes Versions with different Countersinks, Thread Types and Hardened Finishes to match specific Material and Wear Requirements.

Why Concave Cutters matter for efficient Material Processing

Designed for use in slow-running single-shaft Shredders, Concave Cutters produce a focused, high-impact Cut that helps break down bulky or tough Materials more effectively than flat designs. When the Hohlkehle (Concave) is pronounced, the Cutter achieves a more aggressive bite into the Material, reducing recirculation and improving Throughput. Conversely, slanted Concave profiles with reinforced Threading increase stability and extend the Service Life of the Cutter Head under mixed or contaminant-rich loads.

How these Cutters deliver measurable operational benefits

Operators benefit from clear Improvements in Downtime Reduction and Replacement Intervals by choosing the right combination of Cutter Geometry and Hardening Method. Case-hardened Concave Cutters offer excellent Fracture Resistance for contaminated Streams, while Through-hardened Cutters deliver longer Wear Life on clean, homogeneous Material. Compatibility with established Machine Lines simplifies retrofits and minimises installation Effort.

Where Concave Cutters make the biggest difference

Installation is particularly advantageous when processing bulky Plastic Components, Scrap Wood or Heterogeneous Waste where stable, repeatable Cutting behaviour is required. These Cutters are therefore essential for Recycling Facilities, Waste Management Operations and Manufacturing Plants that integrate Pre-Shredding into their Material Preparation Chain.
