Analysis of Failure of Grinding Balls During Service

The ball mill employing the balls was stopped after the operating cycle and the cracked balls were withdrawn. The mean diameter of such balls was about 70 mm. The crack was cleaned in order to prevent mechanical and chemical damage. The specimens for the study were taken from the region of the crack and from adjacent regions.

SAG vs. AG Mills: Understanding the Key Differences

SAG mills use a combination of steel balls and rock particles as grinding media, while AG mills use only the ore itself. Both types of mills are used for grinding ore in mineral processing operations, but SAG mills are larger in size and can grind larger quantities of ore. AG mills, on the other hand, are smaller and are typically used for ...
