About Our Removable Circular Shredder Blades

The ShengAo Removable Circular Shredder Blades (Round Knives) are precision-engineered cutting components designed for double shaft recycling and pelletizing equipment. These innovative blades feature a modular, removable design that makes them easy to replace and maintain without disassembling the entire rotor shaft. As the core cutting elements in twin-shaft shredders and granulators, they are used across the plastic recycling industry to efficiently reduce material size for pelletizing, reprocessing, or disposal. Engineered for maximum performance, durability, and user convenience in demanding industrial environments.

Premium Material & Construction

Our removable circular blades are manufactured from premium tool steels selected for specific applications. We offer a wide range of materials including 9CrSi, 55SiCr, H13, Cr12MoV, and D2 steel, each chosen for its unique balance of hardness, toughness, and wear resistance. The circular design with removable mounting allows for individual blade replacement when worn, significantly reducing maintenance downtime and cost. Each blade undergoes precision machining and grinding to achieve exact dimensions and a perfectly sharp cutting edge. Advanced heat treatment processes ensure optimal hardness and durability for long-lasting performance in continuous plastic recycling operations.

Key Features & Benefits

Designed for maximum efficiency and minimal downtime, these removable blades offer significant advantages. The removable design allows for quick replacement of individual worn blades without dismantling the entire rotor assembly, saving hours of maintenance time. Their exceptional long life time reduces the frequency of blade changes and lowers operational costs. The high efficiency cutting geometry ensures optimal material throughput with minimal energy consumption. Safety is enhanced through secure mounting systems that prevent blade dislodgement during operation. The circular shape provides excellent cutting geometry and distributes wear evenly across the blade surface, extending service life and maintaining consistent cutting performance.

Application Industries & Materials

These versatile removable circular blades are specifically designed for the plastic recycling industry but are equally effective across multiple material streams. They excel in processing plastics of all types (PET, HDPE, PVC, PP, etc.) for pelletizing and reprocessing. Additionally, they are highly effective for metal, rubber, paper, wood, packaging materials, and solid waste. Key applications include twin screw plastic extrusion machinery, plastic pelletizing lines, recycling plants, manufacturing facilities, and solid waste processing centers. The blades are ideal for operations requiring frequent blade changes or those processing abrasive materials that cause uneven wear patterns.

Customization & Quality Assurance

We specialize in providing fully customized blade solutions tailored to your specific equipment and material requirements. We can customize blade diameter, thickness, mounting hole pattern, cutting edge geometry, and material specification to match your exact machine model and application needs. Our commitment to quality is demonstrated through comprehensive video outgoing-inspection where you can verify the product before shipment, and official machinery test reports that verify material composition and hardness specifications. Despite the lack of a formal warranty, our blades are built to the highest standards, and we provide online technical support to ensure optimal performance. Each blade is carefully packaged to prevent damage during shipping, arriving ready for installation.

Frequently Asked Questions (FAQs)

Find answers to common questions about our Removable Circular Shredder Blades and their applications in plastic recycling.

Removable circular blades offer several key advantages: 1) Reduced Maintenance Time: Individual blades can be replaced without disassembling the entire rotor shaft, saving hours of downtime. 2) Cost Savings: Only the worn blades need replacement, not the entire set or rotor. 3) Flexibility: Different blade materials or geometries can be used in specific positions to optimize wear. 4) Easier Sharpening: Blades can be removed for sharpening and then reinstalled. 5) Inventory Management: You only need to stock individual blades, not complete rotor assemblies. This makes them ideal for plastic recycling operations with frequent blade changes.
For abrasive plastics (like fiber-reinforced materials or heavily contaminated waste), 9CrSi and 55SiCr are excellent choices due to their high wear resistance and good toughness. 9CrSi offers good hardenability and wear resistance, while 55SiCr provides higher strength and fatigue resistance. H13 is a hot-work steel with superior toughness and thermal fatigue resistance, making it better for applications with high impact or heat generation. For pure abrasion resistance in plastic recycling, we often recommend starting with 9CrSi or 55SiCr. We can help select the optimal blade material for plastic recycling based on your specific material mix.
Yes, absolutely. We specialize in custom mounting solutions for removable circular blades. To ensure perfect compatibility with your existing twin-shaft shredder (whether it's Vecoplan, Weima, Forrec, or any other brand), please provide: 1) The machine model number, 2) Photos of the current blade mounting system, 3) Sample of the old blade, or 4) Detailed engineering drawings. We can replicate or adapt the mounting hole pattern, locking mechanism, and dimensions to match your equipment exactly. Our goal is to provide drop-in replacement blades that work seamlessly with your existing system.
The replacement or sharpening interval for removable circular blades depends on several factors: 1) Material Processed: Abrasive materials (like reinforced plastics) wear blades faster. 2) Throughput: Higher volumes shorten blade life. 3) Blade Material: Premium steels like 9CrSi last longer. 4) Cutting Conditions: Proper alignment and sharpness affect wear. Generally, blades should be inspected regularly for wear. Signs for sharpening/replacement include: reduced throughput, increased power consumption, poor particle size, or visible edge rounding. With proper maintenance, our blades can last several hundred to thousands of hours in plastic recycling applications. We recommend keeping spare blades on hand to minimize downtime.
Our lead times vary based on order quantity and customization complexity: Standard delivery for pre-configured blades is 5-10 workdays. For custom orders: 1-100 pieces: 20 days (Fast Track), 101-300 pieces: 30 days (Standard Schedule), 301-500 pieces: 35 days (Bulk Production), and >500 pieces: negotiable (Custom Schedule). Lead times begin after order confirmation and final specification approval. For urgent needs, expedited options may be available. We strive to be a reliable supplier of industrial cutting blades with predictable delivery.
Yes, we provide comprehensive quality documentation to ensure transparency and confidence: 1) Machinery Test Report/Certificate verifying the chemical composition of the steel material. 2) Hardness Test Report showing HRC values at multiple points. 3) Dimensional Inspection Report confirming critical measurements. 4) Video Outgoing-Inspection - a custom video we send before shipment showing the actual blades, their features, and packaging. This documentation is part of our commitment to being a trusted supplier of high-quality recycling equipment blades.
Yes, our removable circular blades are designed for both shredding (coarse reduction) and pelletizing (fine cutting) applications in the plastic recycling industry. The key difference is often in the blade geometry and cutting edge design. For shredding, blades may have a more aggressive hook angle for tearing. For pelletizing, blades are designed for clean, precise cutting to produce uniform pellets. We can customize the blade profile, edge angle, and hardness based on your specific application—whether it's primary size reduction in a shredder or final pelletizing in an extruder. We are experts in plastic pelletizing blade technology.
We provide comprehensive online after-sales support to ensure your complete satisfaction: 1) Technical Consultation: Assistance with blade selection, installation, and troubleshooting via email, phone, or video call. 2) Usage Guidance: Recommendations on optimal operating parameters to maximize blade life. 3) Replacement Parts: Quick supply of additional blades or related components. 4) Problem Resolution: If any issues arise, we work diligently to diagnose and resolve them. While we don't offer a formal warranty, our commitment to quality means we stand behind our products and will work with you to ensure they perform as expected in your plastic recycling operation.
