Built for Every Recycling Application
Cumberland Knives are engineered for the specific demands of each industry, from plastics granulation to e-waste shredding.
Plastics Recycling
Granulators and shredders in plastics recycling demand consistent cut quality and long blade life. Cumberland knives are precision-ground for low speed granulators, central granulators, heavy duty granulators, and beside-the-press granulators to maintain tight particle size distribution across high-volume runs.
Common Applications
- Low speed and central granulator lines
- Beside-the-press and heavy duty granulators
- Plastic lumps, purge, and startup scrap reduction
Paper and Document Shredding
High-volume paper shredding operations require blades that stay sharp through millions of cuts. Our hardened steel counter knives deliver consistent performance on document destruction and cardboard processing lines.
Common Applications
- Secure document destruction
- Cardboard and corrugated shredding
- Office paper and archive processing
Metal Recycling
Scrap metal shredding puts extreme demands on cutting edges. Cumberland knives for metal applications are manufactured from premium tool steels with heat treatment optimized for impact resistance.
Common Applications
- Aluminum and light metal shredding
- Ferrous scrap size reduction
- Wire and cable processing
E-Waste Processing
Electronic waste contains mixed materials that challenge standard blades. Our e-waste cutting knives are designed to handle circuit boards, plastics, and metals in a single pass through multi-purpose shredders and combination shredder and granulator systems.
Common Applications
- Circuit board and PCB shredding
- Hard drive and storage media destruction
- Mixed electronics size reduction
