About Our Single Shaft Shredder Blades

The single shaft shredder rotor blade and counter blade are the core component of industrial shredding systems. Our standard 34x34x20mm and 40x40x24mm square blades are engineered for maximum performance, durability, and long wear life in demanding recycling applications. They are designed to withstand the extreme forces of single-shaft shredders, efficiently reducing the size of various materials for easier handling, recycling, or disposal. These high-performance knives are a reliable solution for continuous operation with minimal maintenance.

Premium Material & Construction

Our blades are manufactured from premium high alloy tool steels, specifically 1.2379, D2, and SKD11. These materials are globally recognized for their exceptional wear resistance, high hardness, and excellent toughness. Each blade undergoes a specialized heat treatment process to achieve an optimal hardness of 58-60 HRC, providing the perfect balance between edge retention and impact resistance. The precise manufacturing ensures a high-quality cutting edge with minimal burrs, promoting smooth material feed and consistent shredding performance in your industrial shredder.

Key Features & Operational Benefits

Designed for longevity and efficiency in the toughest recycling environments, our blades deliver significant operational advantages. The primary key benefits are a long wear life and high-performance cutting. The combination of high alloy steel and precise heat treatment provides superior resistance to abrasion from materials like PET, wire, and metal fragments. This robust construction ensures high rigidity, preventing deformation under heavy load, which maintains cutting accuracy and protects your shredder's drive system. These features translate directly into reduced downtime for blade changes, lower operating costs, and sustained high throughput, maximizing the return on investment for your recycling operation.

Application Industries & Materials

These heavy-duty blades are engineered for a broad range of size-reduction tasks across multiple industries. They are highly effective in processing waste plastics (including PET bottles, HDPE, film, and lumps), wood pallets and construction waste, non-ferrous metals, electrical cables, copper wire, rubber tires, and general industrial waste. Industries that rely on these durable blades include plastic recycling facilities, electronic waste (e-waste) processing plants, metal recycling yards, cable and wire recovery operations, tire recycling, and municipal solid waste (MSW) management. Whether installed in a primary waste reduction line or a dedicated material recovery facility, our single-shaft shredder blades deliver reliable, efficient performance.

Customization & Comprehensive Quality Assurance

We specialize in providing tailor-made OEM blade solutions. While we offer standard sizes, all specifications—including dimensions, thickness, tolerance, and even material grade—can be customized to fit your specific single-shaft shredder model and exceed OEM specifications. Our commitment to quality is transparent and verified: we provide official machinery test reports and video outgoing-inspection for every order, giving you confidence before shipment. Although we do not offer a standard warranty, our focus on premium raw materials and controlled manufacturing ensures a durable, high-performance product. Blades are securely packed in standard export wooden boxes, arriving ready for installation.

Frequently Asked Questions (FAQs)

Find expert answers to common questions about Long Wear Life Single Shaft Industrial Shredder Blades for plastic, wood, and metal recycling.

D2 (1.2379) tool steel offers significant advantages for industrial shredder blades. Its high chromium content provides exceptional wear resistance against abrasive materials like PET, wire, and glass-filled plastics. When heat-treated to 58-60 HRC, it maintains a sharp cutting edge much longer than standard carbon steels, directly contributing to a long wear life. Additionally, it has good toughness to withstand the impact forces in a single shaft shredder. This combination reduces blade change frequency, minimizes downtime, and lowers the total cost of ownership for your recycling operation.

For PET shredding, the material itself is abrasive and can quickly dull a soft blade. A hardness of 58-60 HRC provides excellent edge retention, ensuring clean cuts and consistent flake size over extended periods. For cable and wire shredding, the challenge is the combination of soft insulation and hard copper/aluminum cores. This hardness range allows the blade to slice through the metal without chipping while still maintaining sharpness against the abrasive insulation. It's the optimal balance to resist both abrasive wear (from PET/insulation) and maintain necessary toughness against metal impact, maximizing blade life in mixed waste streams.

Service life varies significantly based on the material processed (clean PET vs. contaminated film), shredder setup, and maintenance. For a typical 24/5 plastic recycling operation processing post-consumer PET bottles, our D2/SKD11 blades (58-60 HRC) can often last between 200 to 400 operating hours before requiring rotation or sharpening. For more abrasive streams (e.g., glass-filled plastics), life may be 100-200 hours. Proper blade gap adjustment, regular cleaning, and avoiding non-shreddables (like metals in plastic stream) are key to maximizing life. We recommend monitoring throughput and particle size as indicators for maintenance.

Absolutely. Our OEM service is a core offering. We can manufacture single shaft shredder blades to any dimension required by your machine. Provide us with technical drawings, CAD files, or a sample blade, and we can replicate or improve upon the design. We customize length, width, thickness, mounting hole patterns, edge angles, and even the material grade. This ensures a perfect fit and optimal performance for your specific shredder model, whether it's a European, American, or Asian make. Customization allows you to optimize blade life and cost for your unique waste stream.

The MOQ of 100 pieces is standard for our high-volume production of industrial shredder blades. This quantity aligns with the typical consumption patterns of commercial and industrial recycling facilities that run continuous operations and require spare blades on hand to minimize downtime. Producing in larger batches allows us to optimize material procurement, heat treatment furnace loads, and machining setups, which in turn helps us maintain competitive pricing and consistent high quality. For smaller trial orders or specific R&D projects, we are open to discussion—please contact our sales team to explore possibilities.

Our Video Outgoing-Inspection provides transparent, visual quality assurance for your order. The video typically includes: 1) Overview of the batch with your order number visible. 2) Dimensional checks using calibrated measuring tools (calipers, micrometers) on randomly selected blades to verify critical dimensions (e.g., 40x40x24mm). 3) Visual inspection of cutting edges and surfaces for defects. 4) Hardness spot test demonstration with a portable durometer to confirm 58-60 HRC range. 5) Final packaging process, showing the blades being placed securely in wooden export boxes. This gives you confidence that your high-performance knives meet specifications before they ship.

Yes, our blades made from D2/1.2379 steel at 58-60 HRC are designed to handle mixed waste streams that may include both plastics and light metals (like aluminum cans, thin gauge steel, or copper wire). The high wear resistance protects against plastic abrasion, while the controlled hardness provides sufficient toughness to handle occasional metal pieces without catastrophic failure. However, for dedicated, high-volume metal shredding (e.g., thick steel), a different grade with higher impact toughness might be recommended. For general MSW or e-waste recycling where material separation isn't perfect, our blades offer a robust and cost-effective solution.

Our standard lead time is 30 days after deposit receipt for orders up to 100 pieces. This covers material procurement, precision machining, heat treatment, quality inspection, and packing. For orders of 1-100 pcs, the detailed schedule is 32 days. We understand urgent situations in recycling plants. Expedited production is sometimes possible for a premium, depending on current factory capacity and material availability. For critical downtime scenarios, please contact us immediately with your specifications and required quantity—we will do our best to work out an accelerated schedule to get your single shaft shredder back up and running.
