Engineered with dimensions of 350*32*3mm, these blades are optimized for consistent particle size output, smooth operation, and reliable performance in demanding shredding applications. As the core cutting component of dual-shaft shredders, they ensure efficient material processing for recycling and waste management operations.

Premium Material & Construction

Our double shaft shredder blades are manufactured from premium Cr12MoV tool steel, a high-carbon, high-chromium alloy steel known for its excellent wear resistance, good toughness, and high hardness after heat treatment. This material composition provides superior performance in demanding plastic grinding applications where resistance to abrasion and edge retention are critical. Each blade is precision-machined to exact dimensions of 350mm diameter, 32mm thickness, and 3mm cutting edge, ensuring perfect fit and synchronization in dual-shaft systems. The blades undergo specialized heat treatment processes to achieve optimal hardness and durability, followed by precision grinding to create sharp, consistent cutting edges that deliver reliable performance throughout their service life.

Frequently Asked Questions (FAQs)

Find expert answers to common questions about Double Shaft Shredder Cutting Blades for plastic grinding and size reduction applications.

The dimension 350*32*3 represents the three critical measurements of our double shaft shredder cutting blades: 350mm refers to the outer diameter of the round blade, 32mm indicates the thickness or width of the blade from mounting surface to cutting edge, and 3mm specifies the cutting edge thickness. This standardized sizing ensures compatibility with specific double shaft shredder models and proper intermeshing with counter-rotating blades. The 350mm diameter provides optimal cutting surface area for efficient material processing, while the 32mm thickness offers sufficient structural strength to withstand the torsional forces in dual-shaft operation. The 3mm cutting edge represents the thickness of the actual cutting portion, optimized for clean shearing action in plastic grinding applications.

Cr12MoV is a high-carbon, high-chromium cold work tool steel that offers an excellent balance of properties ideal for shredder cutting blades. Its composition provides several advantages: 1) High Wear Resistance: The high carbon and chromium content creates hard carbide particles that resist abrasion from plastic materials, extending blade life. 2) Good Toughness: The molybdenum and vanadium additives improve toughness, preventing chipping and cracking under impact loads. 3) High Hardness Potential: Can be heat-treated to achieve high hardness levels (typically HRC 58-62) while maintaining reasonable toughness. 4) Dimensional Stability: Exhibits minimal distortion during heat treatment, ensuring blades maintain precise dimensions. This combination makes Cr12MoV particularly suitable for plastic grinding applications where blades encounter abrasive materials and require long service life.

Double shaft shredder blades and single shaft blades differ significantly in design, function, and application: 1) Cutting Action: Double shaft blades work in pairs on counter-rotating shafts, creating a powerful shearing/scissoring action. Single shaft blades typically use a combination of rotating and stationary blades for a cutting/tearing action. 2) Blade Design: Double shaft blades are often round or hexagonal with precise intermeshing geometry. Single shaft blades are usually rectangular or square. 3) Torque & Power: Double shaft systems provide higher torque and can handle tougher, bulkier materials including light metals. Single shaft systems are better for relatively homogeneous materials. 4) Output Control: Double shaft shredders offer better control over output particle size. 5) Applications: Double shaft is preferred for mixed waste, e-waste, and heavy-duty recycling; single shaft is common for plastic lumps and pre-consumer scrap.

For an order of 15 pieces of our 350*32*3 cutting blades, which falls within the 1-20 pieces quantity range, our standard lead time is 15 days after order confirmation and deposit receipt. This efficient timeline includes material procurement of Cr12MoV steel, precision machining to achieve the exact 350*32*3 dimensions, specialized heat treatment to optimize hardness and durability, final grinding and sharpening of cutting edges, comprehensive quality inspection (including dimensional verification and hardness testing), and proper packaging for shipment. For orders exceeding 20 pieces, we negotiate a custom production schedule based on your specific requirements and volume. This predictable lead time helps you plan shredder maintenance and blade replacement effectively.

Yes, our Cr12MoV cutting blades are well-suited for processing engineering plastics and reinforced materials such as glass-filled nylon, carbon fiber composites, fiberglass-reinforced plastics, and other abrasive polymer compounds. The high wear resistance of Cr12MoV steel is particularly beneficial for these abrasive materials, as it maintains cutting edge sharpness longer than standard tool steels. However, for optimal performance with highly abrasive reinforced plastics, we recommend: 1) Ensuring your shredder has sufficient power and torque for the material. 2) Implementing a controlled feed rate to prevent overloading. 3) Considering more frequent sharpening intervals compared to processing standard plastics. For extreme abrasion conditions, we can discuss alternative materials like specialized tool steels with even higher wear resistance for your plastic grinding application.

Proper maintenance of double shaft cutting blades is essential for optimal performance and longevity: 1) Regular Inspection: Check for edge wear, nicks, or cracks. Monitor for increased vibration or noise that might indicate blade imbalance or wear. 2) Timely Sharpening: Don't wait until blades are completely dull. Sharpening at appropriate intervals maintains cutting efficiency and prevents excessive stress on the shredder. Cr12MoV blades can typically be reground multiple times. 3) Proper Cleaning: Remove plastic buildup or melted material from blade surfaces and shafts regularly. 4) Correct Installation: Ensure blades are installed with proper alignment and torque specifications to prevent uneven wear. 5) Lubrication: Follow manufacturer guidelines for shaft and bearing lubrication. 6) Balancing: When replacing blades, consider replacing sets rather than individual blades to maintain rotor balance. Keeping spare blades on hand minimizes downtime during maintenance.

Yes, we provide both machinery test reports and video outgoing-inspections for our cutting blades, offering comprehensive quality assurance. The machinery test report is a formal document that provides certified data on material composition (verifying Cr12MoV steel), hardness measurements, dimensional accuracy, and other technical specifications. This serves as official documentation for quality compliance. The video outgoing-inspection is a customized visual record created specifically for your order, showing our quality control team conducting final inspections, measuring critical dimensions with precision tools, checking cutting edge quality, and documenting the overall condition before packaging. This dual approach—formal documentation plus visual verification—provides maximum confidence in the quality and specification compliance of your industrial shredder blades, surpassing what most suppliers offer.

Absolutely. While our standard lead time of 15 days applies to orders of 1-20 pieces, we regularly handle orders of various quantities. For orders exceeding 20 pieces, we negotiate a custom production schedule based on your specific volume requirements, desired delivery timeline, and our current production capacity. We can accommodate both smaller orders for maintenance replacement and larger bulk orders for new equipment installations or extensive inventory stocking. For very large volume requirements, we can often offer production efficiencies and potentially adjusted pricing. We recommend contacting us directly with your specific quantity needs so we can provide a tailored lead time and quotation. This flexibility ensures we can meet the needs of both small recycling operations and large industrial facilities requiring double shaft shredder blades.
