New Used Sag Mills for Sale

SAG is an acronym for Semi-Autogenous Grinding. SAG mills are essentially autogenous mills, but utilize grinding balls to aid in grinding like in a ball mill. A SAG mill is generally used as a primary or first stage grinding solution. Attrition between grinding balls and ore particles causes grinding of finer particles.

Processes

An autogenous mill is, by definition, a mill that employs coarse ore as the grinding medium while it is itself being ground. In pracice, autogenous grinding has to be changed to semi-autogenous grinding, since lack of adequately hard ore necessitates the addition of large steel balls to maintain the required grinding rate.
