Frequently Asked Questions (FAQs)

Find expert answers to common questions about ShengAo Heavy-Duty Shredder Blades for metal, scrap, and industrial recycling applications.

Single-shaft shredder blades are typically square-shaped "moving knives" with curved edges that work against a stationary counter-blade. They are designed for primary reduction of bulkier, tougher materials like metals and thick plastics. Multi-shaft shredder blades (including double and four-shaft) are often "claw" or "hook" shaped knives mounted on intermeshing rotors. These blades use a combination of tearing, shearing, and crushing actions, making them highly effective for high-volume processing of materials like waste plastic, rubber, and municipal solid waste. The choice depends on your target material, desired output size, and throughput requirements for your industrial recycling operations.
Choosing the optimal shredder blade material is critical for longevity and cost-effectiveness. Cr12MoV is a high-carbon, high-chromium alloy steel offering excellent wear resistance and hardness, ideal for general-purpose shredding of scrap metal, tires, and hard plastics. 9CrSi is an alloy tool steel known for good toughness and wear resistance, suitable for a balanced range of materials. H13 is a hot-work steel prized for its high toughness and thermal fatigue resistance, making it the best choice for shredding high-tensile strength metals (e.g., automotive steel) or in applications where significant heat buildup occurs. Consult with our engineers for a precise recommendation based on your specific metal shredding or industrial waste processing needs.
We provide comprehensive custom shredder blade solutions through OEM and ODM services. Customization options include: Dimensional Changes: Non-standard lengths, bore sizes, thickness, and specialized tooth geometries (e.g., staggered, wave-shaped) to fit any machine model. Material Upgrades: Switching to more advanced alloys like tungsten carbide-tipped blades for extreme abrasion resistance when processing highly abrasive scrap. Heat Treatment Protocols: Tailoring the quenching (vacuum or salt bath) and tempering process to achieve the perfect balance of hardness and toughness for your specific material stream. We work with your specifications or samples to deliver the exact replacement industrial blades you need.
Our quality assurance process is stringent and multi-stage. It begins with strict control from the original technical drawing and selection of certified raw materials. During manufacturing, we employ advanced processes like precision forging and controlled atmosphere (vacuum or salt bath) quenching to ensure metallurgical integrity. Each batch undergoes multiple hardness tests (e.g., Rockwell testing) to verify it meets the specified HRC range. Final precision grinding ensures dimensional accuracy and burr-free edges. We can provide video outgoing-inspection reports and machinery test reports for full traceability and to give you complete confidence in the durability of your heavy-duty recycling equipment components.
Lead times vary based on order complexity and quantity. For standard bulk orders of existing designs, the typical production time is 15-20 days. For fully custom-designed blades requiring new tooling and engineering, the lead time may extend to approximately 30 days to ensure all specifications are met. Sample orders for testing purposes can usually be completed in 7-10 days. We prioritize clear communication and provide updated timelines throughout the manufacturing process to ensure your industrial shredding operations experience minimal disruption.
Heat treatment is arguably the most critical step in determining a shredder blade's service life and failure mode. Proper quenching (e.g., in a vacuum furnace or salt bath) transforms the steel's microstructure to achieve maximum hardness. Subsequent tempering (often 4-5 cycles) relieves internal stresses, increases toughness, and prevents brittleness that leads to chipping or catastrophic breakage. An incorrect or substandard heat treatment process can result in blades that wear out too quickly, deform under load, or suffer from edge chipping when impacting hard objects in scrap metal recycling. Our controlled, multi-stage thermal processing is key to delivering blades that offer optimal wear resistance and impact strength.
Yes, we encourage and support sample testing to ensure our blades meet your performance expectations for your specific waste shredding application. Samples are available for a fee, and the associated freight costs are typically borne by the buyer. The lead time for sample production is generally 7-10 days. This process allows you to verify dimensional fit, material performance, and durability in your own machinery before committing to a larger production order. It's a risk-free way to validate that our custom crusher blades are the right solution for enhancing your size reduction efficiency.
Our heavy-duty shredder blades serve a vast array of industries involved in recycling, resource recovery, and volume reduction. Key sectors include Metal Recycling: Processing scrap iron, steel, non-ferrous metals, and end-of-life vehicles (ELV). Solid Waste Management: Shredding municipal and industrial solid waste (MSW & ISW), bulky items, and construction debris. Tire Recycling: Primary and secondary reduction of car and truck tires.
