1.Feature of Forged Steel Grinding Ball with Supper Hardness apply for all kinds of Mineral Processing
1) In general, grinding steel ball has high hardness: surface hardness to 58-65 HRC, volume hardness of 56-65 HRC
2) impact toughness high: impact toughness more than 12 J / cm2.
3) broken rate is low: the actual broken rate is not higher than 0.5%.
4) loss of grinding forged steel ball round rate is low.
