1.Forged grinding balls 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. 2.Features: 1) forged grinding ball has high hardness: surface hardness to 58-65hrc, volume hardness of 57-64hrc 2) impact toughness high: impact toughness more than 12j / cm2. 3) broken rate is low: the actual broken rate is not higher than 0.5%. 4) loss of forged grinding ball round rate is low. 5) dropping test in 8m high tester for more than 20, 000 times.

Forged Grinding Ball According to the present situation of 9.75 4.88m SAG mill, grid plate hole 60mm, and we recommended your company changed ball diameter from the original 120 to 125, filling rate from 9-10% to 11-12%, so that it is more effectively to increase the grinding quality and processing ore. Base on the high quality raw material, the advanced automated equipment, the heat processing and the strict quality control system, we can improve the surface hardness of grinding ball up to 58-65HRC and impact toughness of grinding balls is over 12J/cm,�. Features of forged grinding ball 1) High hardness: surface hardness of forged grinding balls is to HRC 58-65. The tolerance of the core hardness and surface hardness is not over 2HRC; 2) Good Impact Toughness: impact toughness of forged grinding balls is over 12J/cm,�; 3) Low Broken Rate: the actual broken rate is not higher than 1%.

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.
