FEATURES:
Even hardness: The range of surface hardness is HRC55-67, volume hardness is HRC52-65;
Low broken ball rate: the actual breakage rate is lower than 0.5%;
High impact value: impact toughness is more than 12J / cm2;
Long service life: dropping test in 6m tester is more than 20,000 times;
Superior wear and corrosion-resistance: In the wet grinding environment, the steel ball has good resistance to acid and alkali corrosion, and its grinding effect can exert the greatest advantage in the wet grinding environment of the metal mines;
High grinding efficiency: outstanding perfermance applied in large-scale SAG mills as well asball mills.
