Frequently Asked Questions (FAQs)

Find expert answers to the most common questions about H13 Double Shaft Shredder Blades for heavy-duty recycling applications.

H13 hot-work tool steel is chosen for double shaft shredder blades due to its exceptional combination of properties ideal for demanding conditions. It offers superior toughness and impact resistance, crucial for handling mixed waste streams that may contain metals or other hard contaminants. H13 also has excellent thermal fatigue resistance, meaning it can withstand the repeated heating and cooling cycles during continuous shredding without developing cracks—a common failure mode in other steels. Additionally, it provides good wear resistance when heat-treated to HRC 56-58. This balance makes H13 the preferred material for heavy-duty industrial shredding applications involving plastic, wood, and metal.
The key differences lie in design, cutting action, and application. Single shaft shredder blades (often mounted on a single rotating rotor) typically use a combination of rotating and stationary blades for a cutting/scissoring action, suitable for relatively homogeneous materials like plastic lumps or wood. Double shaft shredder blades are mounted on two intermeshing, counter-rotating shafts. They employ a powerful shearing and tearing action, providing higher torque, better control over output size, and the ability to handle much tougher, bulkier, or mixed materials (e.g., with metals). Double shaft blades are generally more robust, often made from tougher steels like H13, and are the go-to choice for primary reduction of mixed industrial waste, e-waste, and tires.
Yes, ShengAo's H13 double shaft shredder blades are specifically engineered to handle light metals such as aluminum profiles, thin steel sheets, non-ferrous scrap, and metal components within mixed waste (e.g., from electronic waste or end-of-life vehicles). The high toughness of H13 steel resists chipping and breaking upon impact with metal. However, it is crucial to understand the application limits: these are designed for mixed waste streams or light gauge metals, not for dedicated ferrous scrap shredding (which requires even more specialized, often custom-alloyed hammers). For optimal results and blade life, the shredder should be appropriately sized, and the feed should be controlled to prevent excessive overload from very thick or hard metal pieces.
Our comprehensive quality assurance package for H13 blades includes two key elements: 1) Official Machinery Test Report: This document provides certified data on material composition, hardness (HRC), and key dimensions, offering formal verification that the blades meet the specified standards. 2) Video Outgoing-Inspection: Before shipment, we create a custom video for your order, visually documenting the inspection process. This typically shows checks for surface finish, verification of critical dimensions with calipers, and the overall condition of the blades. This dual approach—documented proof and visual transparency—provides unmatched confidence in the quality and specification compliance of your industrial shredder blades. All this is backed by a 6-month warranty.
For an order of 80 pieces, which falls within the 1-100 pieces quantity bracket, our standard production lead time is 20 days after order confirmation and deposit receipt. This period covers the entire manufacturing process: sourcing of H13 tool steel, precision CNC machining, specialized heat treatment to achieve HRC 56-58, final grinding and finishing to Ra 0.2 surface quality, comprehensive quality inspection (including hardness testing), and secure packaging in wooden cases. This efficient timeline allows for reliable planning of your shredder maintenance and spare parts inventory. For urgent needs, please contact us to discuss expedited options.
The Ra 0.2 surface finish (a measure of surface roughness) is critically important for double shaft shredder blade performance and longevity. A smoother finish (lower Ra value) significantly reduces friction during the shredding process. This leads to several key benefits: 1) Lower Energy Consumption: The shredder motor works less hard, reducing operating costs. 2) Reduced Heat Generation: Less friction means less heat buildup, which helps preserve the blade's hardness and prevents premature thermal fatigue. 3) Improved Material Flow: Processed material is less likely to stick or weld to a smooth blade surface. 4) Easier Cleaning & Maintenance. Achieving this fine finish requires precision grinding and polishing, reflecting a higher level of manufacturing quality essential for high-performance industrial blades.
Absolutely. ShengAo's core strength is OEM and ODM manufacturing of replacement blades for all major double shaft shredder brands, including Vecoplan, SSI, WEIMA, Eldan, Forrec, and many others. To ensure a perfect fit and optimal performance, we need precise specifications. The best references are the original blades (samples), detailed engineering drawings, or the exact machine make, model, and serial number. We can replicate the original design exactly or even improve upon it with material upgrades (like our standard H13) or enhanced heat treatment. This service provides a high-quality, cost-effective alternative to OEM parts, minimizing downtime for your recycling operation.
Proper maintenance is key to maximizing the life of your H13 shredder blades. Key practices include: 1) Regular Inspection: Check for edge wear, nicks, cracks, or excessive clearance between intermeshing blades. 2) Timely Sharpening/Reconditioning: Don't wait until blades are completely dull. Sharpening at the right time maintains efficiency and prevents damage from overloading. H13 blades can typically be reground multiple times. 3) Proper Installation & Torque: Ensure blades are mounted correctly with the specified torque to prevent slippage or imbalance. 4) Cleaning: Remove built-up material (especially melted plastic) from blade surfaces and shafts. 5) Lubrication: Follow the shredder manufacturer's guidelines for bearing and shaft lubrication. Keeping a set of spare blades on hand minimizes downtime during maintenance.
