composition in grinding media balls
Cast Grinding Steel Balls
High Cr media for primary grinding will typically contain maximum levels of eutectic carbide (30 – 35% by volume) and are heat treated to their maximum hardness (HRC 65 – 68). However, not many high Cr balls are used in primary grinding because the improvement obtained in wear resistance relative to steel, typically 25 – 30%, is not enough to offset Its higher cost.

"Grinding media fail if there is a significant variation in chemical composition, hardness and microstructure of the balls. Common failure modes of grinding balls observed in different semiautogenous grinding (SAG) applications are misshapen, surface spalling, shelling, capping and half balls." "Traditionally there has been one manufacturer of cast and forged grinding media in South Africa. This .

The size of grinding media plays a key role in overall performance of the grinding circuit. Larger grinding media has a smaller grinding surface area, but offers a heavier weight that's generally used to break larger ore. Small grinding media has a larger grinding surface area generally chosen to help make smaller ore smaller. In some cases, we find ourselves adjusting the ball size by the millimeter to approach .

Cement mill Wikipedia
A Ball mill is a horizontal cylinder partly filled with steel balls (or occasionally other shapes) that rotates on its axis, imparting a tumbling and cascading action to the balls. Material fed through the mill is crushed by impact and ground by attrition between the balls. The grinding media are usually made of highchromium steel. The smaller grades are occasionally cylindrical ("pebs") rather than spherical.
