Forged Grinding Balls are high-performance grinding media produced via hot forging + quenching-tempering process, designed for ball mills in mining, cement, and metallurgy industries. Compared to cast grinding balls, they feature 20% higher density and 30% lower breakage rate, reducing media consumption cost by $1.2-1.8 per ton of processed material—a significant saving for high-volume operations.
Dense Forged Microstructure: Hot forging eliminates porosity, resulting in a uniform martensitic structure that enhances wear resistance; no casting defects like shrinkage cavities or inclusions.
Precision Hardness Control: Surface hardness is 50-63 HRC with a hardness gradient ≤3 HRC from surface to core, ensuring both abrasion resistance and impact toughness.
Size Consistency: Diameter tolerance controlled at ±0.2mm, enabling even grinding and reducing mill liner wear by 15% compared to irregular cast balls.
Gold Mining: Fine grinding of gold ore in ball mills to <75μm particle size, maximizing gold leaching efficiency.
Cement Manufacturing: Grinding clinker and gypsum mixture, ensuring cement fineness reaches 320-450 m²/kg for optimal strength.
Iron Ore Processing: Secondary grinding of magnetite ore, preparing feed for magnetic separation with consistent particle size distribution.
