WhatsApp: +86 18838072829SAG 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.
WhatsApp: +86 18838072829Grinding coarse ore in a ballmill is done by steel balls of three sizes (5, 4, and 3 inches); fine ore is ground in a tubemill by 2 and 1½inch balls or by flint pebbles or by hard, rounded mine rock such as quartzite. These grinding media wear to small sizes, and new ones must be added regularly to make up the weight.
