Urban construction and renewal create more C&D waste (reinforced concrete, asphalt, wood, etc.).
These materials are tough and abrasive, putting heavy stress on recycling equipment.
Choosing the right shredder blades is key to boosting efficiency.
High-performance blades use strong alloy steels (D2, H13, or manganese steel).
Precise heat treatment gives them a hardness of HRC 50–60.
This hardness works for metal and concrete, but is tough enough to avoid breaking.
This balance makes blades last longer.
Lower energy use: Sharp, angled teeth reduce power needs.
Consistent output: Uniform cutting meets market standards.
Less heat: Smooth surfaces reduce friction and prevent asphalt from sticking.
Cheap blades need frequent replacement and repairs, causing costly downtime.
Premium blades cost more upfront but last 3x longer.
They cut maintenance costs and protect your shredder’s motor, gearbox, and drive system.
Materials are grabbed quickly to avoid slipping or jamming.
Powerful torque uses shearing and tearing to turn large materials into small, uniform pieces.
Staggered blades work continuously, making crushing faster than single-shaft models.
Claw options: 2-claw, 3-claw, 6-claw, 8-claw, 12-claw (more claws = finer output).
Thickness options: 10mm, 20mm, 40mm, 50mm, 75mm (thicker = better for hard materials).
Blades have 3 parts: blade body + clawed blade + auxiliary blade.
Worn parts can be replaced with bolts—cuts downtime significantly.
Main shaft uses spline or hexagonal structure.
Blade inner hole matches the shaft perfectly, preventing cracks or deformation.
Suitable for heavy, non-stop operation.
High Manganese Steel: Tough and impact-resistant. Good for municipal waste, C&D waste, and materials with sand/impurities.
H13 Special Steel: Balances wear resistance and impact resistance. Great for general use and heavy industrial waste processing.
Metals: Aluminum cans, car shells, scrap steel, metal scraps.
Synthetic Materials: Plastic films, bags, barrels, pipes, electronic casings, circuit boards.
Construction/Mixed Waste: Renovation waste, bulky waste, landfill screen rejects (use high manganese steel).
Organic Materials: Used furniture, branches, garden waste, pre-dewatered kitchen waste.
Special Materials: Whole tires (reinforced blades), industrial mixed waste (customizable blades).
Regrind regularly: Worn blades can be reground up to 4 times to restore sharpness.
Adjust gaps: Check and fix blade gaps to keep output consistent and efficient.
Replace damaged blades: If blades chip or crack, replace them immediately to avoid equipment failure.
Tighten bolts: Check blade bolts before and after use to prevent loosening.
Match material to waste: Use SKD-11/Cr12MoV for hard materials; ZGMn13 for high-impact/impurity waste; 9CrSi for soft materials.
Choose the right structure: Prioritize modular quick-change + hexagonal shaft. Use 8/12 claws for fine output; 2/3 claws for coarse crushing.
Save costs: For urban waste, use high manganese steel + variable frequency drive (balances durability and energy savings).
Provide custom details: Give manufacturer your equipment model, shaft diameter, waste type, and desired output size.
