A ball mill consists of a cylindrical shell rotated about its axis by a motor. Heavy metallic balls called grinding media are loaded into the cylinder. The coarse ore (usually from primary crusher) is fed into the mill together with water in wet grinding. The tumbling action of the balls within the revolving mill crushes the feed to finer sizes.

Cast iron balls have been used for decades as a grinding media in all types of grinding applications. Early applications of cast iron grinding balls in mineral processing operations were disastrous due to spalling and premature breakage. Better control and understanding of a high chromium cast iron metallurgical system have led to the use of high chromium cast iron balls in all types of grinding.
