This is particularly true for some of the secondary grinding (primary ball mills) of magnetic iron ores. In magnetic iron ore grinding, the silica levels are continually being decreased from crushing to rod milling to ball milling by intermediate concentration steps. Subsequently, the wear environment becomes progressively less abrasive.

Cast iron grinding balls – grinding media with the geometric shape of a ball and produced by casting molten iron into special forms (sand moulds or chill 

Hot rolled steel balls are manufactured using rotary cutting and roll forging. Rolled balls have replaced traditional cast-iron balls in ball mills.
