6. Production technology: huamin mainly have three kind of production technology for forged steel balls.
1) air hammer forged steel balls
2) rolling-forged automatic production line designed by our ourselves, this production line is controlled by automatic equipment, so the hardness is high and toughness is good.
3) rotary-cut automatic production line, this production line gets five national patent. Currently, we mainly use this production line to produce forged steel balls, so the product quality is quite steady and good.
7. Inspection
Huamin have a full set of inspection equipment.We can test hardness, hadness distribution, chemical composition, impact value, micro-structure, dropping test and so on.
8. Packing
Huamin have two kinds of packing method: steel drums or container bags, this two kind of packing can both meet the requirement of repeated shipping and storage, customers can choose any one.

Forged steel grinding balls:
Suit equipment: both drying and wet ball mills
Tech specs:
The forged plant operates four production lines and sources input barstock directly from hm rolled grinding balls.
It offers a hardness of ¡ö65hrc in surface, slowly decreasing towards the core.
Diameters available: 20 - 15omm (1½¡± --5, ).
Key benefits:
Improved wear resistance due to quenching and tempering..
Steady milling conditions due to wear reduction in wear rate.
It is the best-suited solution to fight wear: it is highly resistant to both abrasion and impact.
5) application field: small balls includes computers, mobile phone lithium battery, rem and mass products like the writing instruments.
The small balls can be further geometrical designed by additional processes. The focus to the micro and nano subject has become much more important in various international development. A positive example is the new process technology for the production of small steel balls.
