Raw Materials & Alloys

Crafted from premium materials for exceptional performance and durability

About Our High-Performance Crusher Blades

The crusher blade is the core component of any plastic recycling and size reduction machinery. Engineered to deliver maximum cutting efficiency, our OEM industrial crusher blades are custom-designed to enhance operational throughput, reduce energy consumption, and minimize downtime. Manufactured with precision for various crusher and granulator models, these blades are built to withstand the most demanding recycling environments while maintaining consistent particle size output and exceptional durability.

Premium Material & Construction

Our crusher blades are primarily manufactured from high-grade 9CrSi tool steel, renowned for its excellent wear resistance, toughness, and ability to maintain a sharp cutting edge. We also offer other premium materials including D2, H13, and other high-performance alloys to suit specific application needs. Each blade undergoes precision CNC machining and specialized heat treatment processes to achieve an optimal hardness of 55-60 HRC, balancing cutting performance with impact resistance. A final rust-proofing surface treatment ensures longevity even in harsh, humid operational environments.

Key Features & Benefits

Engineered for superior performance, our crusher blades offer significant operational advantages. The exceptional material quality and heat treatment ensure a long service life, dramatically reducing the frequency and cost of blade replacements. Precision manufacturing guarantees perfect fit and balanced operation, minimizing vibration and stress on crusher bearings and rotors. With comprehensive quality documentation including Machinery Test Reports and Video Outgoing-Inspection, you receive verified quality assurance. Our efficient 5-day lead time for 1-10 sets ensures minimal disruption to your recycling operations.

Application Industries & Materials

These versatile crusher blades are designed for a broad spectrum of size reduction tasks within the plastic recycling and waste processing industries. They excel in processing post-consumer plastic bottles, films and bags, rigid plastics, plastic lumps and purgings, electronic waste housings, and other recyclable materials. Key industries that benefit include plastic recycling plants, waste management facilities, manufacturing plants with in-house scrap processing, and material recovery facilities (MRFs). The robust design effectively handles contaminated and mixed material streams while maintaining high cutting efficiency.

Customization & Quality Assurance

We specialize in fully customized OEM crusher blade solutions. From exact dimensions and mounting hole patterns to specific material grades and hardness requirements, we tailor every aspect to fit your specific crusher model and material stream. Our commitment to transparency is demonstrated through the provision of Machinery Test Reports, Video Outgoing-Inspection, and detailed drawing formats. Each order is securely packed in wooden cases to ensure safe arrival. Backed by a 1-year warranty and supported by our technical team, we provide reliable cutting solutions for your industrial needs.

Frequently Asked Questions (FAQs) - Industrial Crusher Blades

Find expert answers to common questions about high-performance crusher blades, OEM cutting knives for plastic recycling, material selection, lead times, and quality assurance for granulators and shredders.

For plastic recycling crusher blades, 9CrSi is an excellent, cost-effective choice offering good wear resistance and toughness. For more abrasive materials or longer life, D2 (high-carbon, high-chromium) steel provides superior wear resistance. For applications with high impact or heat, H13 hot-work steel is recommended. The best material depends on your specific plastic type (e.g., PET bottles, film, engineering plastics), contamination level, and desired service life. We provide material consultation to help you choose the optimal crusher knife material.
Service life varies based on material processed, machine load, and maintenance. Our 9CrSi blades at 55-60 HRC typically last 30-50% longer than standard blades in processing common plastics like PET and HDPE. With proper sharpening before excessive wear (recommended at 0.5-1mm wear), a set of blades can undergo multiple regrinds, extending total usable life significantly. We design our industrial cutting knives for long service life to minimize your cost per ton of processed material.
Yes, absolutely. We are an OEM industrial knife manufacturer specializing in custom solutions. Provide us with your old blades, technical drawings, or simply your granulator/crusher make and model. We can replicate dimensions, mounting holes, angles, and material specifications precisely. Customization includes material grade, hardness, cutting edge geometry, and surface treatment. This ensures perfect fit and optimal performance for your machine, whether it's a Rapid, Vecoplan, Engel, or any other brand.
We provide comprehensive documentation for quality assurance: 1) Machinery Test Report: A formal document verifying material composition, hardness (HRC) values, and key dimensions. 2) Video Outgoing-Inspection: A video showing the final inspection process, including measurement of critical dimensions and visual check of each blade. 3) Drawing Format: Technical drawings of the blades for your records. This transparent process ensures you receive high-quality crusher blades exactly as specified.
Yes, our 5-day "Fast Track" lead time is standard for orders of 1-10 sets. This is achieved through efficient inventory management of standard tool steel stocks, optimized CNC machining workflows, and streamlined heat treatment scheduling. The lead time starts from order confirmation and deposit receipt. This quick turnaround is designed to minimize downtime for your plastic recycling operations. For larger custom OEM orders, we provide a negotiated schedule to ensure reliable delivery.
To maximize blade life: 1) Sharpen Regularly: Don't wait until blades are completely dull. Light, frequent sharpening is better. 2) Maintain Proper Clearance: Ensure correct clearance between rotor and bed knives. 3) Check for Damage: Inspect for nicks or cracks after processing contaminated material. 4) Clean Blades: Remove plastic residue buildup which can cause overheating. 5) Correct Installation: Follow torque specifications and ensure blades are seated properly. 6) Store Spare Blades Properly: Keep in a dry place, apply light oil if storing long-term. Proper maintenance can double the effective life of your industrial cutting knives.
The rust-proofing treatment provides crucial protection, especially in the humid environments common in plastic washing and recycling lines. It prevents surface corrosion during storage, shipping, and machine idle periods. This ensures the blades remain in perfect condition until installation and helps maintain the precision of the cutting edges. It does not affect the cutting performance but significantly enhances the blade's durability and readiness for use, protecting your investment in OEM crusher blades.
We primarily supply the crusher blades and cutting knives themselves (rotor knives, bed knives, screen knives). However, we can also supply or recommend compatible mounting hardware (bolts, nuts, washers) upon request. It's important to use high-grade, correctly sized hardware to ensure safe and secure blade installation. For complete knife sets or if you need hardware, please specify this during your inquiry so we can provide a comprehensive solution for your granulator or crusher maintenance.
