About Our Double Shaft Shredder Blades

Double shaft shredder blades are the core cutting components of heavy-duty industrial shredders, designed for high-torque, high-volume size reduction of tough materials. Unlike single shaft systems, these intermeshing dual-rotor blades work in tandem to shear, tear, and crush materials with superior efficiency. Our custom-size double shaft blades are engineered for maximum durability and performance in the most demanding recycling and waste processing applications, including plastic film, scrap metal, and tires.

Premium Material & Construction

We manufacture our heavy-duty double shaft shredder blades from a selection of premium alloy tool steels to match specific application needs. Our standard materials include 55SiCr, 6CrW2Si, SKD-11, D2, DC53, LD, and Cr12MoV. Each material is chosen for specific properties: 55SiCr for exceptional shock resistance in tire shredding; D2 and DC53 for superior wear resistance in metal and plastic processing; SKD-11 for high hardness and dimensional stability. Every blade undergoes precision machining, specialized heat treatment, and high-precision grinding to achieve optimal geometry, hardness (typically HRC 58-62), and a burr-free cutting edge for reliable, consistent performance.

Key Features & Operational Benefits

Engineered for extreme conditions, our double shaft blades deliver unmatched operational advantages. Their heavy-duty construction ensures high rigidity, preventing deflection under the immense torque and load of dual-shaft systems. The exceptional wear and impact resistance of our chosen alloys dramatically extends service intervals, minimizing downtime and maintenance costs. The intermeshing design compatibility ensures smooth, efficient cutting action with minimal energy consumption. Most importantly, all conventional specifications can be fully customized to fit your exact machine model and material stream, ensuring a perfect fit and optimal shredding efficiency.

Application Industries & Materials

These versatile double shaft shredder blades are built to tackle the toughest materials across numerous industries. Primary applications include: Metal Recycling (scrap metal, aluminum, wires, light iron), Tire Processing (car and truck tires), Plastic & Film Recycling (hard plastic lumps, films, purgings, pipes), E-Waste Processing (circuit boards, appliances), Wood Waste (pallets, demolition lumber), and Municipal Solid Waste (MSW). Industries that rely on their performance include scrap yards, tire recycling plants, plastic reprocessing facilities, electronic waste recyclers, and major waste management operations.

Customization & Quality Assurance

We are experts in providing completely tailor-made double shaft blade solutions. We can customize every aspect: dimensions, thickness, hole patterns, cutting edge geometry, and most critically, the alloy steel material to match your specific shredding task (e.g., 55SiCr for tires, D2 for mixed metal). Our commitment to quality is verified through a machinery test report and video outgoing-inspection provided with every order. We back our blades with a 1-year warranty on the core component. Lead times are efficient: 31 days for 1-100 sets, 35 days for 101-500, and 45 days for 501-1000 sets. Bulk orders over 1000 sets are scheduled via negotiation.

Frequently Asked Questions (FAQs)

Find expert answers to common questions about ShengAo Custom Double Shaft Shredder Blades for heavy-duty applications in tire, metal, and plastic recycling.

Double shaft shredder blades operate on two intermeshing, counter-rotating rotors, creating a shearing and tearing action ideal for high-volume, high-torque shredding of tough, bulky materials like tires, metals, and large plastic blocks. They handle higher loads and produce a more consistent output size. Single shaft blades typically use a rotor against a fixed bed, employing a slicing/cutting action better suited for lower-volume, precise cutting of softer or thinner materials like plastic film, textiles, and paper. Double shaft systems and their blades are generally more robust, built for higher stress, and require precise synchronization between the two sets of blades.

For tire shredding applications, 55SiCr or 6CrW2Si are often the preferred choices. 55SiCr spring steel offers exceptional toughness and shock resistance, which is critical for handling the steel belts and beads within tires without chipping or catastrophic failure. While D2 and DC53 offer superior wear resistance, they can be more brittle under extreme impact. For a balanced approach in mixed streams containing tires and other materials, a toughness-optimized version of D2 or a specialized alloy like LD might be recommended. We consult with clients on their specific tire composition (car vs. truck) and shredder model to select the optimal alloy steel for tire recycling blades.

Our 1-year warranty covers defects in material and workmanship for the core component (the blade itself) under normal operating conditions. If a blade fails due to a material flaw (e.g., cracking from internal voids) or a manufacturing error (e.g., improper heat treatment leading to premature wear) within one year from the date of shipment, we will replace the defective blade(s). The warranty does not cover wear from normal use, damage from improper installation, operation outside design parameters (e.g., feeding uncrushable metals), or neglect. To claim, please provide the order information, photos/videos of the issue, and details of the operating conditions. This warranty provides peace of mind for your investment in heavy-duty industrial shredding equipment.

Yes, we specialize in full customization for virtually any brand or model of double shaft shredder. Common brands we cater to include SSI, WEIMA, Vecoplan, Forrec, ZERMA, Genox, and many Chinese OEM models. To proceed, we require either: 1) Original technical drawings (CAD files are ideal), 2) Detailed dimensional specifications (length, width, thickness, hole diameters and positions, edge angle), or 3) Physical sample blades that we can reverse-engineer. We then engineer the blades with the appropriate material and heat treatment. Our ability to customize all conventional specifications ensures perfect fit, optimal performance, and often cost savings compared to OEM parts.

Our Machinery Test Report is a formal document that includes: 1) Material Chemical Analysis verifying the alloy composition. 2) Hardness Test Results (HRC) taken at multiple points across the blade. 3) Dimensional Inspection Report showing actual measurements vs. specifications with tolerances. 4) Visual Inspection Record for surface finish, cracks, and burrs. 5) Heat Treatment Process Record. The complementary Video Outgoing-Inspection provides visual proof: 1) Blade appearance and marking. 2) Live measurement verification using calipers and other tools. 3) Hardness testing demonstration. 4) Final packaging process showing secure wooden case preparation. This dual verification offers complete transparency for quality control in industrial blade procurement.

Lead times vary based on order quantity and complexity: 1) 1 - 100 sets: 31 days. This is our standard production window for most orders. 2) 101 - 500 sets: 35 days. Slightly extended due to larger batch processing. 3) 501 - 1000 sets: 45 days. Allows for efficient scheduling of material procurement and production runs. 4) >1000 sets: Negotiable. We create a custom production schedule. These timelines start from the date of order confirmation and receipt of deposit. For completely new custom designs (no existing drawings), add approximately 5-7 days for engineering and sample approval. We provide regular updates throughout the process.

To ensure a smooth and accurate custom order, please prepare the following information: 1) Machine Details: Brand, model number, and photos of the shredder/chamber. 2) Blade Specifications: Technical drawings (PDF, CAD), OR detailed dimensions (LxWxT, all hole sizes/positions, edge angle), OR send us a sample blade. 3) Material Information: Tell us what you are shredding (e.g., car tires, mixed metal, hard plastic) so we can recommend the best alloy (55SiCr, D2, etc.). 4) Quantity Required: Number of blades per rotor and total sets. 5) Desired Hardness (optional): If you have a specific HRC requirement. Providing clear information upfront minimizes delays and ensures you get the perfect custom double shaft shredder blades for your operation.
