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.
Development of Grinding Media Balls Using Locally Available Materials
Cement mill – Cracks in the mill ends . This case of damage was investigated to decide if repair-welding is a sufficient solution when the ends of a cement mill start to crack and are in danger of breaking. To ensure that the damage is repaired reliably, the cause of the damage must be investigated and weld seams examined carefully.

Grinding Balls. Steel balls ranging from ¾ to 5 in. in diameter are used. Rods range from 1½ to 4 in. in diameter and should be 3 to 4 in. shorter than the inside mill length. Tube mills are usually fed balls smaller than 2 in., whereas 4- or 5-in. balls are more commonly used for ball-mill grinding.
