Designed specifically for processing scrap metal, end-of-life vehicles (ELVs), electronic waste (e-waste), and mixed recyclables, ShengAo hammers maintain crushing efficiency while reducing operational costs. With global e-waste generation exceeding 53 million metric tons annually and metal recycling becoming increasingly crucial for sustainable manufacturing, high-performance shredder components like ShengAo hammers play a vital role in efficient resource recovery systems.
2. ShengAo Shredder Hammers: Features & Functions
ShengAo's engineering focuses on solving core challenges in shredding operations: premature wear, impact failure, and inconsistent performance. Our hammers are designed to maximize throughput while minimizing downtime in heavy-duty recycling operations.
2.1. Premium Manganese Steel Composition
ShengAo hammers utilize specialized manganese steel alloys (Mn13Cr2, Mn18Cr2, Mn22Cr2) that develop exceptional work-hardening properties during operation. The chromium-enhanced manganese steel composition creates a surface hardness that increases under impact, reaching up to 550 HB while maintaining a tough core that resists catastrophic failure. This unique material characteristic makes ShengAo hammers ideal for processing mixed scrap streams containing both ferrous and non-ferrous materials, providing up to 30% longer service life compared to standard hammers when processing challenging materials like automotive shredder residue (ASR) and e-waste components.
2.2. Advanced Manufacturing Process
Each ShengAo hammer undergoes precision casting followed by specialized heat treatment processes that optimize the carbide distribution within the manganese steel matrix. Our proprietary quenching and tempering techniques create the ideal balance between hardness and toughness, preventing premature cracking while ensuring maximum wear resistance. Dimensional tolerances are maintained within ±0.5mm through CNC machining of critical mounting surfaces, ensuring perfect balance and alignment in high-speed shredding rotors operating at 500-700 RPM.
2.3. Optimized Hammer Design
ShengAo offers multiple hammer geometries engineered for specific applications:
- S-Type: Standard rectangular design for general scrap processing
- X-Type: Cross-shaped geometry for enhanced impact on bulky materials
- D-Type: Double-ended design with reversible edges for extended service life
- Special Tooth: Integrated carbide teeth for processing abrasive e-waste
Each design features strategically placed wear zones and optimized weight distribution to maximize kinetic energy transfer during impact.
