Product Introduction
>Product Introduction
CADI (Carbidic Austempered Ductile Iron) Grinding ball is a kind of carrier be used in ball mill / SAG mill in Mining concentration plant , to help crush & mill ore materials.
CADI grinding ball is the Mn/Si/Cr alloy steel ball by casting, this grinding ball material is ADI (Austempered Ductile Iron), finished product hardness is HRC52-58, and after used, this grinding ball surface hardness will be HRC61-63.
This CADI grinding ball impact toughness can be more than 10 J/m2, So it can be used to SAG & Ball mill which mill machinery diameter size more than 6 meters. Its breakage rate probably same as Forged steel ball, but its comsumption amount will be less than Forgedl, probably same as High chromium casting ball.
>Product Advantage
Lower breakage rate
Because this CADI cast grinding ball have higher hardness, and high impact toughness , so the gridning media consumption cost will be better than Forged steel ball and Lower chrome casting ball.
lower breakage & out-of-roundness rate
Depend on controlling raw material quality / advanced casting production equipment & special heat-treatment processing, The CADI cast grinding ball product of NGZR have good Physical Property, large size (more than 100 mm) CADI grinding ball breakage & Out-of-roundness rate will less than 1%; Small size casting ball breakage & Out-of-roundness rate will less than 0.5%

Product Uses
>Product Application
This CADI cast steelg ball is a consumable grinding media, be used to mill & grinding raw material such as mineral ore block to powder by equipment of Ball mill / SAG mill , The application industries as:
1.Mining
Wildly used to mineral processing for Iron mine/ Copper mine /Gold mine Sliver mine/ Lead-Zinc mine / Bauxite mine/ Nickel mine / Manganese mine / Chromium mine / Lithium carbonate mine / Graphite mine / Fluoride mine /Quartz mine etc.
>Product Uses
How to select right type /size and quantity of grinding media?
1.Follow the mill machinery size
In general, The mill machine have larger diameter size , input raw ore with larger size and get higher grinding efficiency, need to select large size grinding ball. When the mill diameter size more than 6 meters, the grinding ball breakage rate will be higher, that should be selecting the grinding ball with high toughness, that need your grinding media supplier make special manufacturing for you.
2.Follow the type of mineral and input & output raw ore size
In mineral processing plant, one stage grinding used large size grinding ball, the secondary fine grinding used small size grinding ball, This CADI grinding media steel ball will get less wear cost and high grinding efficiency.
3.First installation loading grindng media size proportioning
Ball mill first installation , grinding ball quantity should be 35-45% of whole ball mill loading weight, to Follow mill speed / input mineral size /output size and grinding efficiency to adjust grinding media loading weight. First installation will loading 3-5 different size grinding ball, and middle size ball quantity should me more than 50%, thereafter, add large size ball quantity follow the grind media consumption.
