### Semi Autogenous Grinding Mill an overview

Size reduction occurs through a primary crusher followed by semi-autogenous grinding (SAG). Large rocks are screened from the overflow and are sent through a pebble crusher, which recirculates the ore back to the SAG mill. The smaller material after SAG milling is classified by hydrocycloning.
