 — Of course chromium cast balls undergo lower wear rates. As the chromium content increases, wear rate will be reduced. Experience with our grinding balls shows that medium-chromium cast grinding balls (7-12% Cr) will have around 10% lower wear rate compared to 70Cr2 forged grinding balls of the same size that enjoy a small chromium …

Ball mills are horizontal rotating cylindrical or conical steel chambers, approximately one third to half full of steel, alloy steel or iron balls, like that shown in Fig. 4.10 A–C, or flint stones. The size reduction is accomplished by the impact of these balls on the material as they fall back after being lifted by the rotating chamber.

Little significant progress was made in the use of ball bearings until over 70 years later when James Suriray, a French bicycle mechanic, patented his ball bearings and used them to build the winning bicycle in the first bicycle road race in history in late 1869.

Grinding is the process of achieving particle size reduction through attrition and compressive forces at the granular level. The grinding media in a ball mill is typically steel or ceramic balls of varying sizes, depending on the feed size, work index of the ore and the size reduction and distribution required in the discharge.

SAG mill make use of steel balls included with some large and hard rocks for grinding. These mills utilize the balls in making the large fragments of materials broken into pieces. The ball charge of a SAG mill is about 9% to 20%.This process takes place inside the large rotating drum of SAG mill which is filled with balls partially.
