    Semi-autogenous grinding mills (SAG mills)

    Semi-autogenous mills or SAG mills as they are often called can accomplish the same size reduction work as two or three stages of crushing and screening. Often used in grinding at modern mineral processing plants SAG mills reduce the material directly to the desired final size or prepare it for the following grinding stages.
