Overview
Grindball Isfahan’s 125mm forged alloy steel grinding balls are precision-engineered for primary comminution circuits and secondary top-up stages of SAG mills where severe crushing forces collide with abrasive quartz rocks.
Performance & Metallurgy
- High impact toughness (> 12 J/cm²) eliminates spalling and catastrophic breakage during multi-meter drop impacts
- Through-hardening technology guarantees surface hardness of 60-64 HRC and core toughness above 56 HRC
- Proven industrial wear rate below 0.45 kg/t across heavy mineral processing operations
- Spherical geometry retained throughout the wear lifecycle, ensuring uniform energy transfer
