Ad Details:

Blow bars are rotor-mounted steel components in impact crushers that strike materials at 80-120km/h, delivering 90% of crushing force. Their design directly impacts throughput, particle shape, and maintenance costs.
Material Evolution
???? Tungsten Carbide Composite
30% tungsten carbide embedded in steel matrix
5x longer life than manganese steel in abrasive applications (e.g., concrete, quartz)
Handles 200t/h of hard rock with 1mm/day wear
⚙️ Mn18Cr2 High-Manganese Steel
Work-hardens from 200HB to 500HB under impact
Cost-effective for soft materials (limestone, shale) – 30% cheaper than carbide
Design Innovations
✅ Reversible Geometry
Dual-sided design doubles service life to 1,500-2,000 hours (vs 800 hours for single-sided)
✅ 3D-Printed Profiles
Curved edges reduce 20% material rebound, increasing energy efficiency
✅ Modular Mounting
Quick-release bolts cut replacement time from 4 hours to 40 minutes
Performance Metrics
Hard rock processing (granite):
▪ Tungsten bars: 1,800 hours lifespan / 28kWh/t energy
▪ Manganese bars: 600 hours lifespan / 35kWh/t energy
▪ Cube-shaped particles: 92% vs 75% for traditional designs
