Discover the pinnacle of innovation with our sand maker cutter head, a vital wear-resistant marvel for impact sand makers, crushers, and cutting-edge mining machinery. This core component masterfully influences crushing efficiency, minimizes energy consumption, and extends the life of your valuable equipment.
I. Core Performance
1. High Wear Resistance
- Material Advantages: Crafted from high-chromium alloy, high-manganese steel, tungsten carbide alloy, and other composite wear-resistant materials, showcasing a remarkable surface hardness of HRC55-65 (Rockwell hardness). This unparalleled wear resistance ensures longevity, far surpassing ordinary steel.
- Application Scenarios: Perfectly engineered for tackling the toughest ores like granite, basalt, and cobblestone. These cutter heads excel in reducing wear frequency, leading to significant savings in replacement costs.
2. Impact Resistance
- Structural Design: The cutter head boasts a robust composite structure, featuring a 'strong and tough core + wear-resistant surface' design. Utilizing advanced bimetallic liquid-liquid composite casting technology, it achieves a perfect balance of hardness and toughness, adeptly withstanding high-speed impacts without fracturing.
- Dynamic Adaptability: Engineered for stability during high-speed rotations (reaching linear velocities of 60-100m/s), this cutter head seamlessly handles large material chunks, preventing any cracking or deformation from the impact.
3. High Temperature Resistance
- Thermal Stability: Some cutter heads utilize high-temperature-resistant alloys, enriched with elements like nickel and molybdenum. This ensures consistent performance even in extreme temperatures (up to 300-500ºC) generated during crushing, safeguarding against material softening and failure.
4. Precise Adaptability
- Model Customization: Tailor every aspect, from size to weight and installation method, to perfectly fit sand maker models (e.g., 1140, 1360) and rotor structures. Achieve seamless integration with components like the main shaft and hammer shaft, minimizing vibration and noise for smooth operation.
II. Key Features
1. Process Optimization
- Precision Casting: By implementing investment casting and lost foam casting techniques, we ensure exceptional dimensional accuracy (tolerance ±0.5mm) and surface finish, significantly reducing installation and debugging time.
- Heat Treatment Strengthening: Elevate material performance through quenching and tempering processes. Post-treatment, the hardness of high-chromium alloy cutter heads' wear-resistant layer increases by 20%-30%, all while retaining over 40% of core toughness.
2. Long-Life Design
- Life Comparison: Under identical conditions, our high-quality alloy cutter heads boast a service life 2-3 times longer than ordinary manganese steel cutter heads. For instance, in granite crushing, ordinary heads last 500-800 hours, while high-chromium alloy heads extend to 1500-2000 hours.
- Wear Repairability: Some cutter heads offer surfacing repair options using wear-resistant electrodes or flux-cored wires, further prolonging service cycles and reducing overall costs.
3. Convenient Installation and Maintenance
- Quick-Release Structure: Featuring bolt fixation and wedge locking designs, our cutter heads allow single-person quick replacement, significantly minimizing downtime. Each replacement can be completed within 1-2 hours.
- Balance Optimization: Before leaving the factory, cutter heads undergo dynamic balance testing (accuracy grade G6.3) to ensure seamless rotor operation, reducing equipment wear and tear.
4. Environmental Protection and Energy Saving
- **Efficient Crushing** : Experience unparalleled efficiency with our Precision Alloy Cutter Head. Its meticulously designed sharp cutting edge and strategic angle configuration, ranging from a 30° to 45° impact angle, significantly enhance the success rate of one-time material crushing. This advanced design not only minimizes over-crushing but also optimizes energy consumption, achieving reductions of 10%-15%, making it an essential tool for high-performance sand making.
- **Low Dust Emission** : Elevate your operational environment with our superior dust control capabilities. The refined crushing trajectory of our cutter head effectively curtails material splashing. When paired with the state-of-the-art dust removal system, it dramatically lowers dust concentration at the workplace. This ensures adherence to environmental standards, promoting a cleaner, safer, and more eco-friendly work site.
III. Selection Suggestions
- **According to Material Hardness** : Tailor your choice of cutter head to the material at hand for optimal performance. For softer rocks like limestone, high-manganese steel cutter heads are ideal. On the other hand, for handling more robust materials such as quartzite, our high-chromium alloy or tungsten carbide cutter heads are expertly crafted to meet these demands, ensuring efficiency and durability.
- **According to Equipment Power** : Match your cutter head to the power capabilities of your sand making equipment. Our robust, thickened, heavy-duty cutter heads are perfectly suited for large sand makers with power exceeding 300kW, guaranteeing superior impact resistance. Conversely, for smaller equipment, lightweight alloy cutter heads provide the ideal balance of efficiency and performance.
- **Pay Attention to Supplier Processes** : For superior reliability and quality, choose suppliers who prioritize rigorous testing processes. Manufacturers offering capabilities such as spectral analysis and wear testing, including wet sand wear tests, stand out. These evaluations ensure the cutter heads possess consistent material uniformity and stable performance, delivering unmatched reliability for your sand making operations.
