Crafted from premium materials for exceptional performance and durability

About Our Single Shaft Shredder Blades

The single shaft shredder rotor blade and counter blade are the core component of the shredder. They are used in various applications across different industries to reduce the size of materials for easier handling, recycling, disposal, or processing. Our custom-made 40mm square blades are engineered for maximum performance and durability in tackling tough materials like tires and rigid plastics. Designed for high torque and continuous operation, they are the heart of an efficient recycling system.

Premium Material & Construction

Our shredder blades are manufactured from premium heat-resisting high alloy steels like D2, H13, Cr12MoV, and DC53 High-Speed Steel. This material selection guarantees exceptional wear resistance, high toughness, and thermal stability crucial for shredding abrasive tire cords and hard plastics. Each blade undergoes thorough-hardening heat treatment to achieve optimal core strength and is finished to a superior surface roughness of Ra 0.4 or less through precision grinding. This ensures a smooth, burr-free cutting edge for clean incisions, reduced friction, and consistent performance under heavy load.

Key Features & Operational Benefits

Engineered for longevity in the most demanding recycling environments, our blades deliver significant operational advantages. The primary key selling points are high wear resistance and high toughness. This combination allows the blades to withstand the extreme abrasion from tire wire and the impact from mixed plastic streams. The robust construction ensures high rigidity, preventing bending and deformation, which maintains cutting accuracy and protects your shredder's drive train. These features translate directly into extended service life, reduced downtime for blade changes, and lower cost-per-ton processed, maximizing your shredding operation's profitability and uptime.

Frequently Asked Questions (FAQs)

Find expert answers to common questions about Industrial Shredder Blades for tire and plastic recycling.

For tire and mixed plastic shredding, the best steel balances high wear resistance and high toughness. Premium heat-resisting high alloy steels like D2, H13, and Cr12MoV are excellent choices. D2 steel offers outstanding wear resistance against abrasive tire wire. H13 provides superior toughness and thermal stability for continuous operation. For extremely abrasive streams, DC53 or specialized high-speed steel variants are recommended. The key is a proper thorough-hardening heat treatment to achieve the optimal hardness (typically HRC 58-62) that resists chipping while maintaining an edge against abrasion. Our engineers can recommend the best shredder blade material based on your specific material mix and machine type.
Replacement and sharpening intervals depend heavily on the processed material (tires vs. clean plastics), throughput, and blade quality. For tire shredding with high steel cord content, blades may require rotation or sharpening every 150-400 operating hours. For plastic shredding, intervals can be 500-1000 hours. Key indicators for maintenance include: decreased throughput, increased power consumption, uneven particle size, and visible edge rounding or damage. Using premium wear-resistant shredder blades like ours can extend these intervals significantly. We recommend keeping a log and inspecting blades regularly. Many of our blades are designed as reversible or indexable to double service life between full sharpenings.
Absolutely. Customization is our specialty. We manufacture fully customized single-shaft shredder blades to match your exact machine specifications. Provide us with the OEM part number, detailed drawings, or even a sample blade. We can replicate or improve upon the original design, adjusting dimensions, thickness, blade angle, mounting hole patterns, and keyway/groove configuration. We can also advise on material upgrades based on your specific tire recycling or plastic waste stream. This ensures perfect fit, optimal performance, and often longer life than the original equipment manufacturer (OEM) part.
Ra 0.4 (micrometers) is a measure of surface roughness, indicating a very smooth, precision-ground finish. For shredder blades, this level of finish is critical for several reasons: 1) Reduced Friction: A smoother blade surface creates less drag as material flows past, lowering energy consumption and heat buildup. 2) Improved Cutting: A precise, burr-free edge ensures a clean shear rather than a tearing action, producing more uniform chips and reducing fines. 3) Material Release: Processed material like sticky plastics or rubber is less likely to adhere to a smooth blade surface. 4) Corrosion Resistance: A smooth finish provides fewer initiation points for rust, important in wet processing. This precision finishing is a hallmark of high-quality industrial cutting knives.
While hardness (e.g., HRC 60+) resists wear from abrasive tire wire, high toughness prevents catastrophic failure. Tire shredding involves unpredictable shock loads from bead wires, belt packages, and occasional tramp metal. A blade that is very hard but brittle can chip, crack, or even shatter upon impact. Toughness allows the blade to absorb these impacts without failing, merely deforming slightly. Our blades are engineered with this balance in mind, using alloy steels and heat treatments that provide both properties. This ensures the blade maintains its edge integrity through millions of cuts, maximizing blade life for tire recycling and protecting your expensive shredder rotor from imbalance damage caused by broken blade segments.
Lead time depends on order quantity and complexity. For standard custom orders of 1 to 50 pieces, our lead time is 45 days from order confirmation and deposit receipt. This timeline includes material procurement, precision machining, thorough-hardening heat treatment, final grinding to Ra 0.4 finish, quality inspection, and packaging. For orders over 50 pieces, we can negotiate a production schedule, often offering a reduced per-unit time due to batch efficiencies. Urgent orders or simple standard sizes may be expedited – please contact us for a specific quote. We provide regular updates throughout the manufacturing process.
