Shredder Blade
In the demanding recycling industry, your shredder blades are the engine of productivity. TINVO manufactures heavy-duty shredder knives designed to handle the most challenging waste streams—from plastics and rubber to wood and light metals. Our blades are engineered to provide maximum throughput with minimal downtime, ensuring your recycling operation stays profitable.
High-Torque Shredder Blades for Efficient Material Recycling
The twin-shaft shredder blade is a key component of the twin-shaft shredder and is generally made of high-strength and wear-resistant materials such as hard alloys. It is mainly used to crush and shred various waste materials such as plastics, wood, rubber, metals, etc., to turn them into smaller fragments or particles for subsequent recycling or processing.
Specialized Wear-Resistant Alloys: We utilize premium tool steels such as D2 (SKD11), DC53, and specialized alloy steels tailored for high-impact applications. These materials are chosen for their ability to maintain structural integrity under extreme torsional stress.
Optimized Heat Treatment: Through a proprietary vacuum hardening process, our shredder knives achieve a consistent hardness (typically HRC 54-58) that balances a wear-resistant edge with a shock-absorbing core to prevent catastrophic failure.
Precision CNC Machining: Every blade is machined to exacting tolerances to ensure perfect interlocking and clearance between the shafts. This precision reduces the load on your motor and gearbox while preventing material wrapping.
Versatile Tooth Configurations: We offer various hook and tooth designs (single-claw, double-claw, or multi-claw) optimized for different materials, ensuring the most efficient “bite” and consistent output size.
OEM Compatibility: Our engineering team can manufacture replacement blades for all major global shredder brands. We work directly from your drawings or samples to ensure a 100% perfect fit.

The specification diameter range of the blade of the twin-shaft shredder is 20*-80*mm, and the thickness is 20-60mm. Usually, the specification of the tool of the twin-shaft shredder is within this range. Because there are very many types of shredded materials, different materials and different outputs have different requirements for the size and strength of the blade, and the number of cutter teeth also has a relatively large difference (the number of teeth is generally more between 2-20 teeth). Therefore, whether it is on a single shaft or a twin shaft of the shredder blade, it basically needs to be customized so that the performance and strength of the shredder tool can reach a relatively high level.
The commonly used specifications of the blade of the twin-shaft shredder are 20*10mm, 20*20mm, 30*20mm, 30*30mm, 30*40mm, 30*50mm, 350*30mm, 350*40mm, 350*50mm, 40*30mm, 40*40mm, 40*50mm, 45040mm, 45050mm, 50*30mm, 50*40mm, 50**50mm.
