Frequently Asked Questions (FAQs)

Find expert answers to common questions about ShengAo Double Axis Shredder Blades for heavy-duty metal and industrial recycling.

Double shaft shredders offer several key advantages: 1) Higher Torque & Shearing Force: Two intermeshing rotors provide powerful tearing and shearing action, ideal for tough, bulky materials like scrap metal and dense plastics. 2) Lower Speed, Higher Efficiency: They typically operate at lower RPMs with higher torque, reducing energy consumption per ton and minimizing heat generation. 3) Self-Feeding Action: The intermeshing blades actively grab and pull material into the cutting zone, improving throughput. 4) Reduced Jamming: The opposing rotation helps clear jams and process irregular shapes more effectively. 5) Consistent Particle Size: Produces a more uniform output size compared to single shaft systems, which is crucial for downstream sorting or processing in metal recycling operations.
Material selection is critical for optimizing blade life and cost. Choose SKD11 for excellent all-around performance in general metal shredding, offering a great balance of wear resistance and toughness. Choose D2 tool steel for superior wear resistance against highly abrasive materials like shredded aluminum with surface contaminants or glass-filled plastics. Choose H13 hot-work steel when maximum toughness and thermal shock resistance are paramount, such as when processing high-tensile steel, thick metal parts, or in applications where significant heat buildup occurs. For general scrap metal recycling with mixed materials, SKD11 is often the recommended and cost-effective choice.
Our industry-leading 1.5-year warranty provides extensive coverage that reflects confidence in our manufacturing. It covers: 1) Material Defects: Flaws in the SKD11, D2, H13, or HSS steel. 2) Workmanship Issues: Failures due to manufacturing errors in forging, heat treatment, or machining. 3) Catastrophic Failure: Blade breakage or cracking under normal operating conditions, excluding impacts from uncrushable objects (e.g., excavator teeth). 4) Premature Abnormal Wear: Wear significantly faster than expected for the specified material and application. The warranty period starts from the delivery date and is a testament to the quality built into every OEM shredder blade we produce for heavy-duty recycling machinery.
The substantial weight of approximately 30kg per blade (depending on final custom size) is a design feature that directly enhances shredder performance. It contributes to: 1) High Rotational Inertia: Heavier blades store more kinetic energy, helping to maintain consistent rotor speed and power through tough, dense materials without stalling. 2) Increased Cutting Momentum: The mass adds to the shearing and impact force during the cutting action. 3) System Stability: Helps dampen vibration and results in smoother, more stable operation of the entire shredder. 4) Durability: The weight often correlates with a robust cross-section and more material, contributing to overall strength and resistance to bending under extreme loads in metal shredding applications.
For a custom OEM order in the quantity range of 1 to 10 pieces, our standard lead time is 35 days. This period is necessary to ensure the highest quality for your industrial shredder blades. It encompasses several critical stages: engineering review and finalization of your custom specifications, procurement of the specific high-grade steel (SKD11, D2, etc.), precision forging and machining, controlled atmosphere heat treatment, final CNC grinding to achieve high-accuracy tolerances, thorough quality inspection (including hardness testing), and secure packing. For orders exceeding 10 pieces, we negotiate a timeline based on complexity to ensure timely delivery without compromising on our rigorous manufacturing standards.
We engineer high safety level into our blades through multiple factors: 1) Material Integrity: Using certified, defect-free steel and proper heat treatment to prevent catastrophic failure. 2) Precision Balancing: Each blade set is balanced to minimize vibration, which reduces stress on shafts, bearings, and welds, preventing fatigue-related breakdowns. 3) Secure Mounting Design: Precise machining of mounting surfaces and holes ensures a tight, reliable fit to the rotor, preventing loosening during operation. 4) Predictable Performance: Consistent quality and geometry lead to predictable cutting forces and machine behavior. 5) Deburred Edges: All non-cutting edges are deburred for safe handling during installation. These measures protect both equipment and operators in industrial recycling environments.
The three most common blade geometries for double shaft shredders are: 1) Hook or Claw Knives: The most common type, featuring a hooked profile that excels at grabbing, tearing, and shearing bulky, irregular materials like metal scrap, tires, and mixed waste. 2) Staggered or Straight Knives: Feature a more straightforward cutting edge, often used for producing a more uniform particle size in applications like plastic film or paper shredding. 3) Specialty/Profile Knives: Custom-designed profiles for specific materials, such as reinforced edges for cutting wire or unique angles for efficient pipe shredding. The choice depends on your primary material; for general metal and heavy-duty recycling, the hook/claw design is typically most effective, and we can customize the hook angle, depth, and clearance for optimal performance.
Yes, absolutely. We specialize in providing complete, matched sets of OEM-quality blades for your specific double shaft shredder model. A matched set is crucial for balanced operation and includes the correct number of rotor knives for each shaft, often with specific left-hand and right-hand orientations, and may include corresponding counter-knives (bed knives). To ensure a perfect fit, provide us with your machine's make and model, or even better, send us the technical drawings or a sample of an existing blade. We will then manufacture a full set from the same material batch, ensuring consistent hardness, geometry, and performance, which is essential for the smooth and efficient operation of your industrial recycling equipment.
