Product Description

Shandong Huamin Steel Ball Joint-stock Co.,Ltd(Shandong Huamin Casting and Forging Joint-stock Co.,Ltd) is one of the largest manufacturers and exporters for grinding steel ball and rod mill in China, the annual production output is 200,000 metric tons. Our products are mainly exported to USA, Canada, Chile, South Africa, Italy, Greece, Korea and Japan more than 30 countries and regions in the world.


 
The forged steel grinding ball is excellent in surface quality, toughness, and resistance to impact and abrasion. It won't crack and lose circularity easily.
1) In general, forged grinding steel ball has high hardness: Surface hardness to 55-67 HRC, volume hardness of 56-64 HRC
2) impact toughness high: Impact toughness more than 12 J / cm2.
3) broken rate is low: Peel fragmentation resistance property of over 20000 times. The actual breakage rate not greater than 1% and close to 0.
