Currently, the manufacture technology of grinding steel ball includes casting, forging and hot rolling. For common ball mills, the grinding media diameter is 20mm125mm, while for extralarge ball mills, 130mm150mm is better. To choose suitable ball mill grinding media, we need to have a clear understanding of each type steel ball. 1.
Forged Grinding Mills. As the grinding media wears fine enough to be carried out by the uprising velocity in the mill the total media charge will diminish and the power draw will decrease Mining Magotteaux Forged Steel Balls For Grinding Of Sag Mill Forged Steel Grinding Balls for Mining We supply forged steel grinding media balls with diamater 20mm150mm
24/4/2020#0183;#32;In 1870, on the basis of ball mill, rod mill with uniform discharge size was developed. In 1908, a selfgrinding machine without grinding medium was created. From the 1930s to the 1950s, the United States and Germany successively developed roller bowl mills, roller disc mills and other vertical shaft medium speed mills.
forged steel grinding ball has high hardness: surface hardness to 5865HRC, volume hardness of 5764HRC; impact toughness high: impact toughness more than 12J / cm2. broken rate is low: the actual broken rate is not higher than %. loss of forged grinding ball round rate is low. dropping test in 8m high tester for more than 20,000 times.
In most secondary Au, Cu, and Mo grinding, the relative wear rates of high Cr compared to forged steel show a performance improvement of 25 30%, similar to that seen in primary grinding. However, for corrosive environments with low abrasion, the high Cr ball can result In Improvements of 50% or more compared to forged steel.
The difference between cast steel ball and forged steel (5) Simply speaking the cast ball is the heatresisting ball (suitable for dry grinding such as the ball grinder in cement plant) and the forged ball is the corrosionresisting ball (suitable for wet grinding large mines power plants etc) the cast ball is suitable for the grinder while the forged ball is suitable for grinder.
The best way to compare primary versus secondary grinding conditions is to review MBWT data from primary and secondary applications for the same mill. This comparison is presented in Table IV. The Wear Speeds in secondary grinding are found to be 25 40% lower than those seen in primary milling when grinding the same, but finer, ore.
Our wearresistant steel grinding rod is specially used in rod mill for mineral processing. It has high hardness (HRC4555) and strength, which is better than ordinary round steel. The wear resistance is increased by at least 50%, which is extremely high. High cost performance makes our grinding rod widely used in major rod mills in China.

The forging ball is made of highquality steel and the Casting Ball is scrap iron; the forging ball is not easy to be deformed in use because of its better surface quality than the casting ball; the casting ball is only suitable for dry grinding, while the forging ball is naturally corrosion resistant due to the use of highquality steel in Casting Suitable for both dry and wet grinding. Generally speaking, the cast ball
