Features and Advantages of Forged Steel grinding media Ball :
Concentrating on wear-resistant grinding material for 30 years, Huamin Brand steel grinding media 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 media 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 of grinding media balls
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 media 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.
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

3.According to your requirements
1 > High Hardness: Surface hardness: HRC57-67 HRC, volume hardness HRC56-64.
2 > High Impact Toughness: The impact toughness of our grinding balls is more than 12 J / cm2.
3 > Low Broken Rate: the actual broken rate is not higher than 1%.
4 > Good wear-resistant and lower wear rate.
Product Feature
1)High quality
High quality comes from every working procedure for the control . Grinding ball have no great
differences in appearance, but in the actual effect of grinding efficiency is different, this is because
the raw material, heat treatment process, equipment automation level and other factors can lead to
the steel ball steel ball lapping efficiency differences, and ultimately affect the user cost of grinding .
Every working procedure we always follow the details of the accused, by providing more wear-
resisting of grinding ball to help customers to reduce the cost of grinding.
Product Specification / Models
1 > Raw material contrast
Ordinary company : directly using the scrap or various steel grades production, traditional little
involvement in the high rate of grinding materials research and development.
houde : have a deep cooperation with The Chinese academy of sciences and steel plant , according
to different industry standard have in-depth research and development, developed raw material
with higher grinding performance.
Application
2 > Heat treatment of contrast
Ordinary company : Usually use pure water cooling quenching with insulation barrels of tempering ,
the heat treatment method is easy to cause uneven hardness, the lack of resilience, steel ball high
broken rate in practical use.
houde : Closed cooling tower for effective control of quenching temperature within the scope of the
standard, the composite heat treatment technology can improve the internal organization of steel ball,
the ball while guarantee the hardness have sufficient toughness are less likely to break.
