Description

The Description of Grinding Balls:

Our grinding balls have many excellent properties, such as high hardness, light specific gravity, high toughness, less broken, great shock-absorbing, high performance of anti-fatigue and the strong ability of shocking hardened layer. It’s widely used in the field of cement and building materials, thermal powder, the grinding mill of the beneficiation, steel and chemical industry, aerated bricks and alumina industry.
