Crafted from premium materials for exceptional performance and durability

About Our Double Shaft Shredder Blades

The double shaft shredder blades are engineered as the core cutting component for the most demanding industrial shredding operations. Working in synchronized pairs on two counter-rotating shafts, these blades deliver powerful shearing and tearing action to process high-volume materials efficiently. Our custom-designed blades are built to maximize throughput, reduce energy consumption, and handle tough materials like tires, metal scrap, and mixed waste with superior durability and extended service life.

Premium Material & Construction

Our double shaft shredder blades are manufactured from premium-grade High Manganese Steel (Mn13, Mn18), D2, 6CrW2Si, or other high-alloy tool steels known for exceptional wear resistance and impact toughness. These materials are selected based on application needs—manganese steel for high-impact shredding (tires, metals), and alloy steels for abrasive materials. Each blade undergoes precision CNC machining, optimal heat treatment (quenching and tempering), and finishing to achieve target hardness (typically HRC 58-62) and a sharp, burr-free cutting edge. This ensures consistent particle size, reduced maintenance downtime, and the ability to withstand heavy shock loads.

Key Features & Benefits

Designed for industrial endurance, these blades offer significant advantages. The interlocking hook-style tooth design provides aggressive grabbing and tearing action, maximizing throughput for voluminous or tangled materials. Exceptional wear resistance extends service intervals, reducing total operating costs. High impact toughness minimizes damage from tramp metal or unexpected hard objects. Customizable tooth profiles (ripper, shear, claw) allow optimization for specific materials—from soft plastics to steel-reinforced tires—ensuring efficient shredding and reduced energy consumption per ton processed.

Application Industries & Materials

These heavy-duty double shaft blades are engineered for the toughest recycling and size-reduction challenges. They excel in shredding tires (passenger, truck, OTR), mixed metal scrap (non-ferrous, light iron), industrial plastic lumps, municipal solid waste (MSW), electronic waste (WEEE), wood pallets, and hazardous waste. Key industries relying on their performance include tire recycling plants, metal scrap yards, plastic recycling facilities, municipal waste processing centers, electronic waste recyclers, and industrial waste management operations. They are the ideal solution for volume reduction, material liberation, and downstream processing.

Customization & Quality Assurance

We specialize in fully customized double shaft shredder blade solutions. Every dimension—length, width, thickness, shaft bore size, tooth count, and profile—is tailored to fit your specific shredder model (including SSI, Vecoplan, Weima, Forrec, or any Chinese/OEM equipment) and material stream. Our commitment to quality is proven through both Machinery Test Reports and Video Outgoing-Inspection provided with every order, offering complete verification of material, hardness, dimensions, and finish. Backed by a 3-month warranty and securely packed in wooden cases, our blades ensure reliable performance for your critical recycling operations. With a 15-day lead time for orders up to 10 pieces, we ensure a responsive supply chain.

Frequently Asked Questions (FAQs) - Double Shaft Shredder Blades

Find expert answers to common questions about custom industrial double shaft shredder blades for tire recycling, metal shredding, plastic waste processing, and MSW size reduction applications.

For tire shredding and metal scrap processing, the blade material must withstand extreme impact and wear. High Manganese Steel (Mn13, Mn18) is highly recommended due to its exceptional work-hardening property—it becomes harder under impact, enhancing wear resistance. For heavily abrasive metal mixtures, high-chromium alloy steels like D2 or H13 with proper heat treatment (HRC 58-62) offer a good balance of toughness and wear resistance. The choice ultimately depends on the specific mix of materials, shredder design, and desired particle size.
Blade life varies dramatically based on material processed, blade steel, operating hours, and maintenance. For tire shredding, expect 200-500 hours before significant wear or rotation is needed. For mixed metal scrap, life can range from 150-400 hours. For plastics and MSW, blades can last 400-800 hours. Proper blade rotation and timely sharpening can extend overall service life by 30-50%. Monitoring for decreased throughput, increased power draw, and larger output size is key for timely maintenance in industrial waste shredding operations.
Yes, absolutely. We specialize in precise custom replacement blades for all major OEM shredders including SSI, Vecoplan, Weima, Forrec, and others. To ensure a perfect fit, please provide the original part drawing, a physical sample blade, or detailed measurements (overall dimensions, shaft bore diameter and tolerance, bolt hole pattern, tooth profile, and pitch). We can manufacture blades that match or exceed OEM specifications using your preferred material, offering a cost-effective alternative to original parts without compromising performance.
Our 3-month warranty covers manufacturing and material defects that affect the blade's functionality. This includes: Major structural flaws (cracks, breaks not caused by misuse), significant deviations from ordered specifications (incorrect dimensions, bore size), and material defects (improper heat treatment leading to premature failure). The warranty period starts from the date of shipment. It does not cover normal wear and tear, damage from improper installation/operation (overload, foreign objects), or corrosion from processing certain materials. This warranty ensures confidence in your industrial recycling equipment investment.
These are our two key quality assurance documents. Machinery Test Reports are official documents verifying critical parameters: material grade, hardness (HRC) readings at specified points, and key dimensional checks. Video Outgoing-Inspection is a visual recording that shows: the batch of finished blades, close-up measurement verification using calipers/gauges, surface finish and edge condition inspection, and the final packing process into secure wooden cases. Together, they provide transparent, verifiable proof of quality and conformance before shipment, reducing risk for international buyers of industrial shredder parts.
Yes, for standard custom orders of 1-10 pieces, a 15-day lead time is our standard commitment. This timeline is achievable due to our optimized production flow: rapid material sourcing for common alloys, efficient CNC machining scheduling, dedicated heat treatment slots, and streamlined inspection processes. The lead time starts from order confirmation and deposit receipt. For larger orders (>10 pieces) or orders requiring special materials, the lead time is negotiated and may be longer. This fast turnaround helps minimize machine downtime for recycling plants and scrap yards.
The optimal tooth profile depends on the material characteristics: Ripper/Claw profiles are best for tires, textiles, MSW, and tangled materials—they grab and tear. Shear profiles are ideal for clean plastics, wood, and homogeneous materials—they provide a cleaner cut. Combination profiles (e.g., ripper on one shaft, shear on the other) are used for mixed waste streams. Providing details about your primary material, desired output size, and current shredder model allows us to recommend the most efficient profile for your waste processing or recycling operation.
Yes, trial orders are highly recommended and common practice. You can order a small set (1-4 pieces or a single rotor/stator set) to conduct a field test. This allows you to verify dimensional accuracy, fitment, material performance, and output quality in your actual shredder under your operating conditions before committing to a full-scale purchase. The lead time and per-piece cost for trial orders follow our standard terms (15 days for ≤10 pcs). This low-risk approach is essential for establishing confidence, especially when switching suppliers or trying a new blade specification for your tire recycling or metal shredding business.
