Forged Steel 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 56-64 HRC
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.
Forged Steel Ball Products Show:
Our products range from 20mm to 150mm, 1 inch to 6 inch, and we can

also offer all size of products according to clients' demand.
Packing Instruction:
Strong Nylon Bag:
Avalible Bag: 500kg; 1000kg
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.
