Frequently Asked Questions (FAQs) - Dual Shaft Shredder Blades

Find expert answers to common questions about ShengAo High-Performance Dual Shaft Shredder Blades for wood, metal, waste film, and mixed waste recycling.

Dual shaft shredder blades offer several key advantages for tough material processing. The primary benefit is the shearing and tearing action created by two counter-rotating shafts with intermeshing blades, which provides superior cutting force and control over output size. This design excels at handling large, bulky, and heterogeneous materials like mixed construction waste, tires, and metal scraps. It generates lower RPMs with higher torque, reducing energy consumption and wear compared to high-speed single-shaft systems. This makes dual shaft shredders and their blades ideal for primary size reduction in waste recycling, wood processing, and metal shredding applications where material variability is high.

"Silvery" alloy steel typically refers to a high-grade alloy tool steel known for its bright, silvery appearance and superior mechanical properties. It is an excellent choice for shredding wood and metal due to its optimal balance of hardness (typically HRC 55-60) and toughness. This combination allows the blades to maintain a sharp cutting edge against abrasive materials like wood (which contains sand and dirt) while resisting chipping and cracking when encountering occasional metal pieces or hard contaminants in mixed waste streams. Its good wear resistance ensures a long service life, reducing the frequency of blade changes and downtime in demanding industrial shredding operations.

Determining the correct blade specifications requires a few key pieces of information: 1) Shredder Make and Model: This is the most reliable way for us to match the original design. 2) Physical Sample: Sending an old/worn blade allows for exact replication of dimensions, hole pattern (PCD), and thickness. 3) Detailed Drawings: Technical drawings with all critical dimensions. 4) Material Information: Knowing the primary materials you process (e.g., wood, metal, film) helps us recommend the optimal steel grade and hardness. Providing this information ensures the replacement shredder blades will offer perfect fit, function, and performance in your specific size reduction application.

Yes, our dual shaft shredder blades are specifically engineered to handle the challenges of mixed waste processing, including occasional non-ferrous metal contaminants like aluminum cans, small wires, or light gauge steel. The key is the toughness of the silvery alloy steel, which provides high impact resistance to withstand shocks from uncrushable items. However, it is crucial to define the limits: they are designed for occasional and expected contaminants within a primarily non-metallic or soft metallic stream. For dedicated metal shredding or streams with large volumes of heavy steel, specialized metal shredder blades with different metallurgy would be recommended. We can advise on the best blade specification based on your specific waste composition.

Our video outgoing-inspection is a transparent quality control process provided before shipment. For shredder blade orders, the video typically includes: 1) A visual walk-around of the finished blade batch, showing the overall condition and finish. 2) Close-up shots of the cutting edges to demonstrate they are burr-free and properly ground. 3) Demonstration of key dimensional checks (e.g., thickness, hole diameter, width) using calibrated measuring tools like vernier calipers and micrometers. 4) A visual check of the heat treatment marking or hardness test spot. 5) The final packing process, showing the blades being placed into protective packaging within the carton. This video provides you with visual proof that your custom blades meet the agreed specifications before they are shipped.

Our 3-month warranty covers manufacturing defects in material and workmanship under normal operating conditions. This includes issues such as premature cracking, breaking, or abnormal wear that is not attributable to improper installation, operation outside design parameters (e.g., shredding materials much harder than specified), lack of maintenance, or accidental damage. To initiate a warranty claim, customers are typically asked to provide the order number, photos or videos clearly showing the defect, and a brief description of the operating conditions. The warranty period starts from the date of delivery. This warranty underscores our confidence in the quality of our industrial recycling equipment parts and provides customers with assurance for their initial operational period.

While both are dual shaft shredder blades, the optimal design and material can differ: Blades for waste film/plastics often prioritize a sharper, cleaner shear angle to cleanly cut and prevent wrapping of flexible materials. They may be made from steels with very high wear resistance to handle abrasive fillers. Blades for wood shredding prioritize high toughness and impact resistance to handle knots, nails, dirt, and the variable density of wood. They often have a more robust, sometimes hook-shaped geometry to grab and split wood fibers. Our silvery alloy steel offers a good balance for mixed streams, but for dedicated applications, we can customize the edge geometry, hardness, and material grade to maximize performance for either plastic film recycling or wood waste processing.

Yes, we actively encourage trial orders. For quantities of 1 to 10 pieces, we offer a very competitive lead time of just 10 days. This allows you to evaluate the blades' fit, performance, and durability in your own machine under real operating conditions with minimal risk. A trial order helps you verify: 1) Dimensional Accuracy and Fit in your shredder. 2) Cutting Performance on your specific material stream. 3) Initial Wear Characteristics. It's an excellent way to validate our product quality and ensure it meets your expectations for enhancing your recycling or waste processing efficiency before committing to larger volume purchases.
