About Our Single Shaft Shredder Rotary Blades

The single shaft shredder rotor blade and counter blade are the core components of a shredder, comprising a square-shaped moving knife that rotates against a stationary bed knife. Engineered for high cutting efficiency in plastic and rubber granulator crushers, these blades are used across various industries to reduce material size for easier handling, recycling, or further processing. Custom-designed for reliability and durability, they are the critical interface between raw waste and valuable regrind in your recycling line.

Premium Material & Construction

Our single shaft shredder blades are manufactured from premium alloy tool steels, heat-treated to achieve an exceptional hardness range of HRC 56-65. This superior hardness provides exceptional wear resistance and toughness, ensuring high rigidity and impact resistance necessary for shredding challenging plastic lumps, films, and rubber materials. Each blade is precision machined to an outstanding flatness of 0.01 or less, guaranteeing a high-precision, burr-free surface for smooth operation, minimal vibration, and consistent cutting performance in demanding industrial environments.

Key Features & Operational Benefits

Designed for a long service life in continuous plastic and rubber crushing operations, these blades offer significant operational advantages. The high hardness (HRC 56-65) provides excellent wear resistance, significantly extending the interval between sharpening or replacement and reducing operational downtime. The precise construction and high flatness ensure stable and efficient shredding output, consistent particle size, and reduced energy consumption. This translates directly into lower cost per ton processed, higher machine uptime, and improved overall efficiency for your recycling operation.

Application Industries & Materials

These high-performance single shaft blades are specifically engineered for plastic and rubber granulator crushers. They excel in processing a wide range of materials, including plastic lumps, purgings, films, sheets, bottles, containers, PVC profiles, rubber tires, and various post-industrial plastic waste. The primary application is in plastic crushing and rubber recycling. Industries that heavily rely on these durable blades include plastic recycling facilities, tire recycling plants, injection molding and blow molding operations with in-house scrap recovery, and waste management companies.

Customization & Comprehensive Quality Assurance

We specialize in providing tailor-made single shaft blade solutions through comprehensive OEM and ODM services. From specific dimensions to material grade selection, we can customize blades to fit your exact shredder model and material stream. Our commitment to quality is robust, demonstrated through provided video outgoing-inspection and official machinery test reports. Every blade is backed by a solid 6-month warranty and is securely packed in wooden cases to ensure perfect condition upon arrival, ready for immediate installation and reliable operation in your facility.

Frequently Asked Questions (FAQs)

Find expert answers to common questions about ShengAo Single Shaft Shredder Blades for plastic and rubber crushing applications.

Exceptional blade flatness (≤0.01) is critical for optimal single shaft shredder performance. It ensures: 1) Perfect Contact: Uniform pressure distribution between the rotor blade and the stationary bed knife for clean, efficient cutting. 2) Reduced Vibration: Minimizes machine vibration, which protects bearings, shafts, and the machine structure from premature wear. 3) Consistent Particle Size: Delivers uniform cutting force across the entire blade width, producing consistent regrind flake size. 4) Lower Energy Consumption: Efficient cutting with minimal friction reduces motor load. 5) Extended Blade Life: Even wear prevents localized stress points that lead to chipping or cracking, crucial for continuous plastic recycling operations.

The HRC 56-65 hardness range offers a perfect balance for plastic and rubber shredding. High hardness (>HRC 60) provides superior abrasion resistance against filled plastics (e.g., glass-fiber, mineral-filled) and rubber compounds, drastically extending blade life. Simultaneously, maintaining toughness within this range prevents brittle fracture when encountering occasional hard contaminants or dense plastic lumps. This combination ensures the blades retain a sharp cutting edge longer, reduce the frequency of sharpening or replacement, and maintain efficient cutting performance, leading to lower operational costs and higher throughput in your granulator or crusher machine.

In a single shaft shredder system, the rotary blade (or rotor knife) is the square-shaped moving knife mounted on the central shaft. It rotates at a controlled speed, grabbing and feeding material. The stationary bed knife (or counter blade) is fixed to the shredder housing. The primary cutting action occurs in the small clearance between these two components, employing a powerful shearing and tearing force. Typically, the rotary blades experience more wear and are designed for easy replacement. Both require precise alignment and matching hardness for optimal size reduction efficiency. It is often recommended to replace them as a matched set to maintain perfect cutting geometry.

Our video outgoing-inspection provides visual verification of the final product batch, showing: 1) General condition and finish. 2) Packing process into the wooden case. 3) Marking/labeling for traceability. The machinery test report is an official document detailing key quality checks, including: Hardness Test Results (HRC values at specified points), Dimensional Inspection (verification against your drawing, including flatness), Material Certification (alloy grade verification), and Visual Inspection for surface defects. These documents provide transparency and assurance of quality for every order of industrial shredder blades, giving you confidence before installation.

Yes, absolutely. Our comprehensive OEM/ODM service supports full customization to meet your specific machine and application needs. We can manufacture blades to your exact custom dimensions (length, width, thickness, bore size), create custom designs with unique cutting geometries or tooth profiles, and select specialized material grades for enhanced performance. You can provide detailed drawings, CAD files, or even physical samples for reverse engineering. This service is ideal for matching non-standard shredder models, optimizing blade design for a specific material stream (e.g., thin films vs. thick lumps), or creating proprietary blade solutions for your plastic recycling equipment.

ShengAo single shaft blades are highly effective for a broad spectrum of plastic and rubber materials. For plastics: They excel at processing PP, PE, PVC, ABS, PS lumps and purgings, plastic films, sheets, bottles, containers, pipes, and profiles. For rubber: They are suitable for tire sidewalls, rubber scraps, and various rubber products. Single shaft shredders with these blades are particularly adept at handling bulky, thick, or tangled materials that might challenge other shredder types. For highly abrasive materials (e.g., fiberglass-filled plastics), we recommend consulting us for a potential material upgrade to maximize blade service life.

Proper handling is key to preserving the precision of your shredder blades. Upon receipt, keep them in the original wooden case until installation. Store in a dry, clean environment to prevent rust. Always wear appropriate cut-resistant gloves when handling. Avoid dropping or striking the blades against hard surfaces, as this can chip the hardened edges or affect flatness. When unpacking multiple blades, place them on a flat, clean surface with protective separators (like cardboard) between each blade to prevent edge-to-edge contact. Before installation, clean the mounting surfaces on both the blade and the shredder rotor/housing to ensure perfect contact and alignment, which is critical for achieving the advertised cutting efficiency.

We offer competitive lead times to support your operational needs. For urgent orders or small batch samples (1-50 pieces), our standard lead time is 7 days for existing designs. This allows for quick testing and machine compatibility verification. For medium batches (51-100 pieces), the lead time extends to approximately 14 days. For large bulk orders or fully custom-designed blades requiring new tooling, please allow 30 days or more, which will be confirmed during order negotiation. We prioritize clear communication and can often expedite processes upon request, ensuring you receive your replacement crusher blades with minimal disruption to your recycling schedule.
