Applications:

Our double-shaft shredder blades are engineered for high-performance shredding across a wide range of industrial and recycling applications. They effectively process packing materials, metal sprues and housings, aluminum profiles, metal drums, electronic scrap, electrical and household devices, tires, paper waste, plastic scrap, refrigerators, and many other materials.
Split Blade Design Advantages
Metal detachable combined split blades offer unique installation flexibility. The cutter head can be mounted in any configuration, delivering high precision, convenient maintenance, and significantly lower maintenance costs compared to traditional solid blades.
Because the blade is detachable, worn segments can be replaced directly without disassembling the reducer main shaft or the shredder housing. This makes split blades ideal for large shredders where full disassembly is difficult or time-consuming.
Blade Thickness Guidelines
Split blades generally require a minimum thickness of 40 to 50 mm to ensure the structural strength needed for heavy-duty shredding. Thinner split blades are more susceptible to cracking under load. For maximum stability and durability, a blade thickness of 75 mm or greater is recommended.
Solid one-piece blades do not face the same structural constraints, so they can perform reliably at thicknesses of 40 to 50 mm.

Description:

The shredder blade is the heart of your machine. Its material grade, geometric precision, and installation accuracy directly determine shredding efficiency, output quality, and overall equipment lifespan.
Precision Engineering & Spiral Mounting Our blades are arranged in a precision-engineered spiral pattern on the shaft, with calibrated spacers maintaining optimal blade-to-blade clearance (typically 0.2–0.3 mm). This ensures smooth, collision-free operation while maximizing cutting engagement. Blade thickness and tooth count are carefully matched to your specific material profile—whether you’re processing soft films or heavy metal scrap.
Premium Material Selection by Application We engineer blades from industry-leading tool steels, vacuum heat-treated to HRC 55–57 for superior hardness and wear resistance:

Smart Material Matching

Soft/tough materials (rubber, film): Choose Cr12MoV cold-work die steel for maximum abrasion resistance.

Medium-hard materials (wood, general plastics, light metal): 55SiCr alloy spring steel delivers the ideal balance of toughness and durability.

Hard metals & high-heat applications: H13 hot-work die steel withstands extreme temperatures without deformation.
Modular Design & Customization Standard twin-shaft blades feature hexagonal bores with 3-, 6-, 8-, or 12-claw outer profiles. The claw count, blade clearance, and spacer configuration collectively define your output particle size. Available in diameters from 200 mm to 500 mm and thicknesses from 20 mm to 55 mm—fully customizable to your operational requirements.

Shredder Blades with different thickness:

The 10 and 20mm thick blades are suitable for fragile materials such as medical packaging and electrical board.
The 40 and 50mm thick blades are widely used. It is suitable for various materials such as tires, plastic products, wood pallets, film and etc.
75mm thickness blades are used for shredding metal items or plastic/metal compounds such as refrigerators and drums. The blades can handle material up to 10mm in thickness.
