forged steel grinding media ball

Features and Advantages:
 Concentrating on wear-resistant grinding material for 30 years, Huamin Brand steel grinding ball is excellent in surface quality, hardness, and resistant to impact and abrasion. It won't crack and lose circularity easily.
1) High hardness: Huamin forged grinding steel ball has high hardness: surface hardness can reach to 55-67 HRC, volume hardness 56-64HRC
2) High Impact toughness: impact toughness is more than 12 J / cm².
3) Low Broken rate:  peel fragmentation resistance property of over 20000 times. The actual breakage rate is less than 1% and close to 0.
Raw Material:
 As we know, the quality of forged grinding piece depends on the material by 80%. Our products use high-quality round steel from national large-scale steel mill to insure the quality of our products.
The Production Line And Equipment:
The self-developed automatic steel grinding ball production line is our qualified product, and it has won Chinese invention patent. It uses electric furnace instead of conventional coal combustion method, and the rotary cutting technique replaces traditional air hammer, thereby improving production efficiency by 30 times or even higher.
