Why Jaw Plates Matter in Crushing Operations
Jaw plates (fixed and movable) are the core wear parts of jaw crushers. They directly affect crushing efficiency, product size, and maintenance frequency.
Common Challenges:
- Rapid wear from abrasive rocks (granite, basalt, quartz)
- Unexpected breakage causing unplanned shutdowns
- High replacement costs and long downtime
High Manganese Steel Jaw Plates Performance Comparison
Item | Standard Jaw Plates | Shandong Jiujiu Premium Jaw Plates | Improvement |
|---|---|---|---|
Material | Mn13 | Mn13Cr2 / Mn18Cr2 | + Better work-hardening |
Typical Service Life | 100-150 hours | 180-280 hours | +40% ~ 80% |
Hardness (After Work-hardening) | 300-400 HB | 450-550 HB | Significantly higher |
Impact Toughness | Good | Excellent | Lower breakage risk |
Price per Ton | Lower | 15-25% higher | Much lower TCO |
Average Downtime per Change | 4-6 hours | 3-4 hours | Reduced by 25-40% |
