Frequently Asked Questions (FAQs)

Find expert answers to common questions about ShengAo Heavy-Duty Double Shaft Shredder Blades for plastic, metal, e-waste, and industrial recycling applications.

HSS (High-Speed Steel) is ideal for applications with high operating temperatures or continuous operation, as it maintains hardness at elevated temperatures. Stainless Steel offers excellent corrosion resistance for processing wet materials, food waste, or corrosive substances. D2 tool steel provides superior wear resistance for abrasive materials like filled plastics, rubber with grit, or glass-reinforced composites. For general industrial shredding of mixed plastics and light metals, D2 offers the best balance of wear resistance and toughness. For specialized applications, we can recommend the optimal material based on your specific industrial shredding requirements.
Double shaft shredders with intermeshing blades provide several key advantages: 1) Higher torque and tearing force for processing tougher materials like thick plastics, rubber blocks, and light metals. 2) Self-feeding action that pulls material into the cutting zone automatically. 3) Lower speed operation reduces heat generation and energy consumption. 4) More controlled particle size through adjustable screen sizes. 5) Reduced jamming due to the shearing action between counter-rotating shafts. This makes double shaft shredders ideal for heavy-duty industrial applications where single shaft machines would struggle with throughput or material toughness.
For mixed streams containing both plastics and occasional metal contaminants, we recommend HRC 58-60 for D2 or HSS blades. This range provides an optimal balance between wear resistance (for abrasive plastics) and toughness (to resist chipping from metal impacts). Higher hardness (HRC 62-65) offers better wear resistance but increases brittleness risk with hard contaminants. Lower hardness (HRC 56-58) provides more toughness but may wear faster with abrasive materials. For dedicated metal shredding, specialized metal shredder blades with different metallurgy are required. Always analyze your material mix percentage to select the optimal hardness for your industrial recycling operation.
Yes, we can manufacture custom double shaft shredder blades for virtually any model on the market through our comprehensive OEM and reverse engineering services. We work with shredders from major manufacturers like SSI, Vecoplan, WEIMA, Forrec, UNTHA, and many others. To ensure perfect fitment, please provide: 1) Machine make and model. 2) Technical drawings or physical samples of your current blades. 3) Clear photos of the blade mounting system. Our engineering team will create precise CAD drawings for your approval before production. We maintain a growing database of blade specifications for common shredder models to expedite the process for industrial equipment replacement parts.
To maximize blade lifespan in industrial shredding operations: 1) Regular inspection for wear, chipping, or cracking. 2) Proper tensioning of bolts to manufacturer specifications (use torque wrench). 3) Timely rotation of reversible blades to distribute wear evenly. 4) Prompt removal of jammed materials to prevent blade damage. 5) Professional sharpening when edges become dull (maintain original edge geometry). 6) Correct clearance adjustment between rotor and counter blades. 7) Avoid overheating by not overloading the shredder. 8) Clean blades periodically to remove material buildup. Following these procedures can extend blade life by 30-50% in heavy-duty recycling applications.
Uneven wear on double shaft shredder blades typically indicates: 1) Improper blade alignment - check and adjust rotor/counter blade clearance. 2) Uneven bolt tension - retorque all fasteners to spec. 3) Material feed issues - ensure even distribution across the hopper width. 4) Worn bearings or shafts - inspect for play or deflection. 5) Hardness variations in blade material - verify consistency. 6) Asymmetric blade design - ensure all blades are identical. 7) Excessive clearance on one side - adjust to 0.3-0.8mm typically. Document wear patterns with photos and share with our technical team for specific troubleshooting advice for your industrial shredder maintenance.
