Product description

Highlights at a glance

  • High and uniform hardness (Surface hardness: 58-65 HRC, Volume hardness: 56-62 HRC). Excellent hardness gradient from surface to core ensures consistent wear resistance throughout the ball's lifespan.
  • Exceptional impact toughness (Impact value ≥ 12 J/cm 2 ≥12 J/cm 2 ). It can withstand continuous high-drop impacts in large-scale grinding mills without breaking or deforming.
  • Extremely low breakage rate (guaranteed under 0.5%). The dense forged structure eliminates internal defects like porosity, shrinkage, or blowholes typical of cast balls, preventing catastrophic failures.
  • Excellent roundness and shape retention. Retaining a precise spherical shape during long-term milling optimizes grinding efficiency and reduces power consumption.
  • Lower grinding media consumption per ton of ore processed. Increases wear life by 15%-30% compared to cast grinding balls, significantly reducing ball replacement frequency and overall procurement costs.
  • Higher density ( ≥ 7.85 g/cm 3 ≥7.85 g/cm 3 ) yields larger kinetic energy. This higher impact energy accelerates material size reduction and maximizes mill throughput.
  • Sourced from top-tier national steel mills. Raw carbon and alloy steel round bars are customized with precise chemical compositions (C, Mn, Si, Cr, Mo) tailored to specific mining and milling conditions.
  • State-of-the-art automatic rotary cutting and heating forging lines. Precise water/medium quenching and tempering heat treatment eliminate internal stress and refine the microstructure into tough Martensite and Bainite.
  • Ideally engineered for SAG (Semi-Autogenous Grinding) mills and primary/secondary ball mills. Capable of stably supplying large diameter forged balls
    • Frequently asked questions

    We specialize in forged grinding balls, cast grinding balls, grinding cylpebs, grinding rods, liners, and flanges. These products serve as grinding media for ball mills and rod mills in mines, cement plants, power stations, chemical plants, and other industries.

    Yes. We offer customization for special diameters, materials (high/medium/low chromium alloy steel), and hardness requirements. Please contact our sales team for lead times and MOQ details.
