SAG mills, rod mills and ball mills are the classical pieces of grinding equipment employed in gold recovery plants. There is an increasing trend to employ SAG mills (semiautogenous mills) in place of secondary and tertiary crushing and primary grinding. The most common type of rod mill is the overflow mill. There are two typed of ball mills used.

The Azzaroni equation indicates that the correct ball size for the 2.93 m mill is 81 mm. Years of experience show that a 76 mm ball grinds the coarse particles most effectively. Ball size distribution is governed by the wear law of the mill and by the wear characteristics through the cross-section of the balls charged to the mill.
