Frequently Asked Questions (FAQs)

Find expert answers to common questions about ShengAo Industrial Crusher Blades with H13/SKD11 construction for plastic recycling and granulation applications.

H13 and SKD11 are both premium tool steels but with different properties ideal for specific applications. H13 (Hot Work Steel) offers excellent thermal fatigue resistance, good toughness, and moderate wear resistance, making it suitable for applications where blades experience temperature variations or occasional impact. SKD11 (Cold Work Steel, equivalent to D2) provides superior wear resistance, higher hardness (typically HRC 58-62), and excellent dimensional stability, making it ideal for continuous high-volume plastic granulation where abrasive wear is the primary concern. We recommend SKD11 for most plastic recycling applications due to its exceptional wear resistance, while H13 may be preferred for tougher, more variable feedstocks.
Our 6-month comprehensive warranty covers defects in material and workmanship for the core components, specifically the blade itself and related gearbox components under normal operating conditions. This includes protection against: 1) Material flaws (cracks, porosity in the steel), 2) Manufacturing defects (significant dimensional errors preventing installation), and 3) Premature failure due to improper heat treatment. The warranty does not cover normal wear and tear, damage from improper installation/operation, accidents, or processing of inappropriate materials (e.g., metals). To make a claim, provide your order details, photos of the issue, and operational context. This warranty provides significant peace of mind for your industrial recycling equipment investment.
To order customized crusher blades, you can provide specifications in several ways: 1) Technical Drawings: CAD files (DXF, DWG) or detailed PDF drawings with all dimensions, tolerances, hole patterns, and material specifications. 2) Physical Sample: Send us an existing blade (even if worn or broken) for precise reverse engineering. 3) Detailed Measurements: Provide accurate measurements of length, width, thickness, all hole diameters and their center distances, cutting edge angle, and any special features. 4) Machine Information: Provide the make, model, and serial number of your crushing machine, which may allow us to reference existing specifications. Our engineering team will review your information and may request clarification to ensure perfect compatibility with your industrial granulator equipment.
The HRC 58-62 hardness range represents the optimal balance for plastic granulator blades: 1) Wear Resistance: Hardness above HRC 58 provides excellent resistance to abrasive wear from plastics, especially filled or reinforced materials. 2) Toughness Balance: Hardness up to HRC 62 maintains sufficient toughness to resist chipping and cracking from occasional hard contaminants or impact. 3) Edge Retention: This hardness level allows blades to maintain a sharp cutting edge through extended production runs, ensuring consistent particle size. 4) Grindability: Blades in this range can be effectively sharpened when needed. Harder blades (>HRC 62) become brittle and prone to chipping, while softer blades (industrial plastic recycling operations.
Our Video Outgoing-Inspection provides comprehensive visual documentation of your blades before shipment: 1) Visual Quality Check: Close-up examination of blade surfaces, edges, and identification markings. 2) Dimensional Verification: Live demonstration of key measurements (length, width, thickness, hole positions) using calibrated instruments like calipers and micrometers. 3) Edge Quality Assessment: Inspection of cutting edge sharpness, angle consistency, and absence of burrs or defects. 4) Hardness Spot Check: Demonstration of hardness testing on sample blades (when applicable). 5) Packaging Process: Showing proper placement in wooden cases with protective materials. 6) Quantity Verification: Final count of blades before sealing the package. This transparency ensures you receive exactly what you ordered for your industrial crushing needs.

Yes, our SKD11 and H13 crusher blades with HRC 58-62 hardness can handle glass-filled and reinforced plastics, but with important considerations: 1) Moderate Fill Levels: They perform well with glass fiber content up to 30-40%. 2) Reduced Service Life: Abrasive filled materials will wear blades faster than virgin plastics—expect 30-50% shorter life depending on filler content. 3) Optimized Geometry: We may recommend specific cutting edge angles to reduce cutting forces and abrasion. 4) Maintenance Schedule: More frequent sharpening or replacement should be planned. For highly abrasive materials (e.g., >50% mineral fillers), we can discuss specialized treatments or alternative materials. Always inform us about your specific material composition for the best industrial blade recommendation.
Proper installation and maintenance maximize blade life and performance: Installation: 1) Clean all contact surfaces thoroughly. 2) Follow manufacturer torque specifications for bolts—overtightening can cause stress cracks. 3) Ensure proper blade-to-counter blade clearance (typically 0.1-0.3mm). 4) Check rotor balance after installation. Maintenance: 1) Monitor for signs of wear: increased power consumption, poorer granulate quality, reduced throughput. 2) Sharpen blades when cutting edges become rounded—use proper grinding techniques to maintain original geometry. 3) Replace blades when width is reduced by 10-15% from original. 4) Rotate blades periodically for even wear. 5) Keep spare blades on hand to minimize downtime. Proper maintenance extends service life and ensures optimal performance of your plastic granulation system.
