Hot Rolling Balls Ball Mill Balls Forged And Cast Grinding Ball suppliers
1.Feature:
1) High Hardness: surface hardness of ball mill grinding meda ball is to 58-68 HRC and volume hardness is to 55-63 HRC;
2) High Impact Toughness: impact toughness is more than 12 J/cm2;
3) Low Broken Rate: the actual broken rate is not higher than 1%;
4) Even Wear-resistance: the loss of ball round rate is 50-300g/ton.
