Features of High Output Continuous Grinding Ball for Ball Mill in Factory for Crushing Aluminum Cans
1) In general, casting grinding ball has high hardness: surface hardness to55-68 HRC, volume hardness of 53-63 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 1%;
4) loss of grinding forged steel ball round rate is 50-300g/ton
