About Our Double Shaft Shredder Blades
The ShengAo Wear-Resistant Double Shaft Shredder Blades are precision-engineered cutting components designed for the demanding world of industrial shredding and granulation. These intermeshing blades work in pairs on two counter-rotating shafts to shear, tear, and reduce tough materials efficiently. As the core component of double shaft shredders and granulators, they are used across various industries to process materials for recycling, disposal, or further manufacturing. Available in multiple jaw configurations (3-jaw, 8-jaw, 12-jaw, etc.), our blades are engineered for maximum cutting efficiency, durability, and longevity in continuous operation.
Premium Material & Construction
Our double shaft shredder blades are manufactured from premium-grade tool steels renowned for their exceptional properties. We primarily use SKD-11 (similar to D2) for its outstanding wear resistance and H13 hot-work steel for its superior toughness and thermal fatigue resistance. Other available high-performance materials include 9SiCr, 55SiCr, Cr12MoV, and high-speed steels like W6Mo5Cr4V2. Each blade undergoes advanced heat treatment processes such as salt bath furnace quenching or vacuum furnace quenching to achieve optimal hardness (typically HRC 58-62) and internal microstructure. The cutting edges are finished with numerical control (CNC) grinding to achieve a precise sharpness rating of 18N-30N and a burr-free surface for smooth, efficient cutting action.
Key Features & Benefits
Designed for a long service life in the most abrasive environments, these blades deliver significant operational advantages. Their exceptional wear resistance directly translates to fewer blade changes, reduced maintenance downtime, and lower cost per ton processed. The high hardness ensures the cutting edge stays sharp, maintaining consistent particle size and throughput. The blades are engineered with high sharpness from the start, reducing power consumption and improving cutting efficiency. Furthermore, the precise manufacturing with tight tolerances (e.g., thickness tolerance of ±0.002mm) ensures perfect intermeshing of the two shafts, preventing jams and minimizing vibration for stable and reliable shredding performance.
Application Industries & Materials
These versatile blades are the workhorse of modern recycling and size reduction. They are highly effective in crushing a vast range of industrial and post-consumer waste, including: Plastics (bottles, films, lumps, pipes), Cardboard & Paper, Tires (car and truck), Scrap Metal (non-ferrous, light gauge), Wood, Rubber, and Municipal Solid Waste (MSW). Key industries that rely on our double shaft blades include plastic recycling plants, tire recycling facilities, metal recycling yards, wood processing plants, e-waste recycling operations, and waste-to-energy plants. They are essential for preparing materials for further processing, baling, or use as Refuse Derived Fuel (RDF).
Customization & Quality Assurance
We specialize in providing fully customized blade solutions tailored to your specific machine model and application. We can customize the diameter (200mm-500mm), thickness (20mm-55mm), inner hole type (hexagonal, octagonal, round with keyways), jaw count, and material grade to match your exact requirements. Our commitment to quality is absolute, demonstrated through comprehensive video outgoing-inspection where you can see the finished product before shipment, and official machinery test reports verifying material composition and hardness. Every blade is protected with anti-rust coating and securely packed in robust wooden cases for safe international shipping, arriving ready for installation and immediate productivity.
