Raw Materials & Alloys

Crafted from premium materials for exceptional performance and durability

About Our Square Shredder Blades (Bottom Stop Model)

The ShengAo Square Shredder Blade (Bottom Stop Model) is engineered as a core component for industrial single and double shaft shredders. Specifically designed with a square profile and bottom stop feature, these blades provide superior stability and prevent axial movement during high-torque shredding operations. Our blades are used across various industries to efficiently reduce the size of diverse materials for recycling, disposal, or further processing. Engineered for maximum performance and durability in the toughest environments.

Premium Material & Construction

Our square shredder blades are manufactured from premium high-speed steel grades, primarily DC53, D2, and SKD-11. DC53 offers exceptional toughness and wear resistance, making it ideal for shredding mixed and challenging materials like metals and hard plastics. The Bottom Stop design ensures precise positioning on the shredder shaft, eliminating slippage and maintaining optimal cutting geometry. Each blade undergoes precision machining for a burr-free surface, followed by advanced heat treatment to achieve the perfect balance of hardness (typically HRC 58-62) and impact resistance for long-lasting performance.

Key Features & Benefits

Designed for extended service life in continuous, demanding recycling operations. The square shape with bottom stop provides unmatched stability, reducing vibration and wear on the shredder shaft and bearings. Their exceptional wear resistance translates to fewer blade changes, lower maintenance costs, and increased uptime. The impact-resistant design can handle unexpected contaminants like small metals or stones in the waste stream. High rigidity prevents deformation under heavy loads, ensuring consistent shredding size and throughput efficiency throughout the blade's lifecycle.

Application Industries & Materials

These versatile square shredder blades are perfect for a wide range of size reduction tasks in resource recovery and waste management. They are highly effective in processing plastics (bottles, films, lumps), metals (non-ferrous scrap, light gauge), paper & cardboard, textiles, rubber, and municipal solid waste (MSW). Key industries that benefit include recycling stations, power stations (for RDF/SRF production), environmental decomposition facilities, waste management companies, and manufacturing plants with in-house scrap processing needs.

Customization & Quality Assurance

We specialize in providing fully customized square blade solutions. We can tailor dimensions (length, width, thickness, bore size), the specific design of the bottom stop, material grade, and hardness to fit your exact shredder model (like Weima, Vecoplan, Forrec, etc.) and material stream. Our commitment to quality is demonstrated through comprehensive video outgoing-inspection and official machinery test reports for material verification (hardness, composition). Each set of blades is securely packed in robust wooden cases to ensure perfect condition upon arrival, ready for installation and immediate productivity gains.

Frequently Asked Questions (FAQs)

Find quick answers to common questions about our Bottom Stop Square Shredder Blades, material selection, and industrial recycling applications.

The Bottom Stop design is a critical feature for secure blade mounting. It consists of a machined flat or notch at the base of the square blade that positively locates against a corresponding stop on the shredder rotor. This prevents the blade from rotating or shifting axially during operation, especially under high torque and reversing loads common in industrial shredding. This ensures consistent cutting geometry, reduces wear on the blade and shaft, and enhances overall shredding stability and safety, making it a preferred choice for heavy-duty recycling applications.
For mixed waste shredding (e.g., MSW, C&D waste), which often contains unpredictable contaminants, DC53 is generally recommended. It offers superior toughness and impact resistance compared to D2/SKD-11, while still maintaining excellent wear resistance. This helps the blade resist chipping or cracking when encountering occasional metals, stones, or hard objects. D2/SKD-11 offers slightly higher wear resistance and is excellent for more homogeneous but abrasive streams like plastics or paper. We can help you select the optimal blade material for recycling based on your specific waste composition.
Yes, absolutely. We are experts in manufacturing precision replacement blades for all major shredder brands including Vecoplan, Weima, SSI, Forrec, Granutech, and many others. Simply provide us with the machine model number, OEM part number, or better yet, a sample blade or detailed engineering drawing. We will replicate the dimensions (including the bottom stop detail, bore size, square dimensions, and thickness) exactly or even improve upon the original material specification (e.g., upgrading to DC53) for longer life. We are a leading supplier of aftermarket shredder blades.
Key indicators for shredder blade replacement include: 1) Reduced Throughput: The machine takes longer to process the same amount of material. 2) Increased Power Consumption: The motor draws more amps due to dull blades. 3) Poor Shred Size: Output particles become larger and more irregular. 4) Excessive Vibration or Noise: Worn or chipped blades cause imbalance. 5) Visible Wear: The cutting edges are visibly rounded, chipped, or the blade height has reduced significantly. Regular inspection and maintaining a spare set of industrial blades is recommended to minimize downtime.
For orders of 1 to 50 sets of our standard square shredder blades, the typical lead time is 15 days after order confirmation and deposit receipt. This includes production, heat treatment, quality inspection, and packing. For larger bulk orders (>50 sets), the lead time is negotiable and often can be scheduled in phases. We prioritize efficient production to get your recycling machine blades to you quickly. Custom designs requiring new tooling may add extra time, which we will confirm upfront.
Yes, we provide comprehensive quality assurance documentation with every order: 1) Material Test Certificate verifying the chemical composition of the steel (e.g., confirming it is genuine DC53, D2, etc.). 2) Hardness Test Report showing HRC values at multiple points on the blade. 3) Dimensional Inspection Report. 4) Video Outgoing-Inspection - a custom video showing the final blades, key measurements, and packaging. This transparent process ensures you receive high-quality industrial cutting blades that meet specifications.
Yes, we manufacture square shredder blades for both single shaft shredders (rotor and counter blades) and double shaft shredders (intermeshing rotor blades). The design principles differ: single shaft blades often work against a fixed counter blade, while double shaft blades intermesh with each other. Our engineering team understands these differences. We can produce complete sets—including rotor blades, counter blades, spacers, and bolts—for either system, ensuring perfect fit and optimal cutting action for your specific waste shredding equipment.
We use robust, export-grade packaging to ensure your blades arrive without damage. Standard packaging includes: 1) Individual Blade Protection: Each blade is coated with anti-rust oil and wrapped. 2) Wooden Case: Blades are securely fastened inside a strong plywood or wooden case with internal bracing to prevent movement. 3) Weather Protection: The wooden case is lined with waterproof material. 4) Clear labeling with part numbers, quantity, and handling instructions. For very large orders, we use palletized wooden crates. Our packaging meets standards for sea and air freight, ensuring safe delivery of your recycling plant spare parts worldwide.
