Professional Forged Grinding Balls Supplier for Iron Ore Copper Ore Gold Mine Ball Mill

Product details

Ultra-Low Breakage Rate (Under 1%): Manufactured using advanced precision rotary cutting and automatic forging technology, ensuring zero internal porosity or cavities, resulting in virtually no breakage in large SAG and ball mills.

Consistent Surface-to-Core Hardness (58-65 HRC): Engineered with professional oil-water cooling heat treatment systems. The hardness gradient is strictly controlled to maintain optimal wear resistance throughout the entire lifespan of the ball.

Superior Impact Toughness (Ak > 12 J/cm²): Excellent impact resistance allows our grinding media to withstand continuous, high-energy impact in mills larger than 5 meters without deformation, cracking, or spalling.

Premium Raw Material Control: Sourced directly from top-tier national steel mills. We use strictly customized carbon and alloy steels (e.g., 60Mn, B2, B3, B4) with optimized alloy compositions for maximum structural density.

Precise Sizing & Perfect Roundness: Available in a full size range from 20mm to 150mm. The extreme dimensional accuracy and roundness improve mill grinding efficiency and reduce power consumption per ton of ore processed.

TUV & ISO9001 Certified Quality: Every production batch undergoes rigorous quality testing (including drop testing, Rockwell hardness testing, and chemical analysis) to guarantee 100% compliance with international mining standards.
