The Jinyang JY Series Cone Crushers represent a significant achievement in domestic high-end mining equipment manufacturing in China. The series is a flagship product line born from independent R&D, notably achieving a major breakthrough in 2014 with the JY500, China's first domestically developed complete cone crusher unit. These crushers are engineered to deliver performance comparable to leading international counterparts while offering significant advantages in total cost of ownership, reliability, and parts compatibility.
Key Technical Details & Features:
Independent R&D & Domestic Breakthrough: A core product line developed through proprietary innovation, filling domestic gaps in high-end and large-sized cone crusher technology (e.g., JY500, JY800).
Performance & Interchangeability: Designed for direct performance comparison and interchangeability of wear parts with leading international models, providing customers with supply security and flexibility.
Key Technical Enhancements:
Spiral Bevel Gear Drive: Optimized from straight-cut bevel gears to improve transmission smoothness, precision, stability, and reliability.
Reinforced Mainframe Structure: Enhanced internal cavity dimensions and wall thickness for increased overall rigidity and reduced wear.
Advanced Control System: Features Siemens PLC-based control (e.g., S7-1200, WinCC) for automated operation, real-time monitoring, setting adjustment, and protection.
Proven Performance & Cost Advantage: Validated through extensive field applications, most notably in side-by-side comparisons with international brands at Jiangxi Copper Group (JCC). Data demonstrates comparable or superior throughput and product gradation, along with significantly longer liner life (e.g., JY500: 850-900 hrs vs. HP500: ~700 hrs), leading to substantial lifecycle cost savings for customers.
Full Product Range & Customization: Offers a complete model range from JY100 to JY800, with cavity designs (Extra Fine to Extra Coarse) that can be optimized for specific ore characteristics (hardness, moisture) to maximize capacity and product quality.
Quality Assurance: Each machine undergoes a no-load test run before leaving the factory to ensure stability and that all parameters (current, temperature, pressure) meet requirements.
