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. Overflow discharge and grate discharge

The primarily used equipment in crushing are jaw crushers, gyratory crushers and cone crushers whereas rod mills and ball mills, usually closed circuited with a classifier unit, are generally employed for grinding purposes in a mineral processing plant. Crushing is a dry process whereas grinding is generally performed wet and hence is more energy intensive.
