Grinding Steel Ball for Mining
Our Grinding Steel Ball have following advantages:
Uniform hardness: surface can reach 60-65HRC
High wear resistance: 10%-30% longer than common products
High impact value: greater than 14J/cm2
Low breakage: below 1%
High quality grinding steel balls we produce mainly use in mining and cement industry. Our grinding balls are widely used in gold mines, copper mines, zinc mines, iron mines, siver mines, cement plants, chemical plants and building materials industry.
we have been able to see more and more customers adding value due to the use of our products.
We can supply casting balls with High and Low Cr:
