Recently, our company independently developed a kind of ultra-high willful low chromium grinding ball, which can be widely used in super large ball mill, semi autogenous mill and autogenous mill at home and abroad.

After the company's scientific research and continuous attempts, the company has achieved good results in 2014, and developed ultra-high toughness low chromium grinding ball, which has the following advantages:

1. Ultra high toughness. At present, the minimum impact toughness without notch is 19.2j/cm2, which is higher than 15J / cm2 of forged steel ball. It can manufacture 10-200mm steel ball, which is used in super large ball mill, SAG mill and Ag mill with all known diameters;

2. Light weight, which can reduce the mechanical wear and power consumption of ball mill;

3. The hardness is very uniform, and the hardness difference between the core and the surface is less than 1 HRC.
