Autogenous grinding mills (AG mills) liming

Autogenous mills, or AG mills, 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, AG mills reduce the material directly to the desired final size or prepare it for the following grinding stages.

SAG mills (semi-autogenous grinding mills) liming

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.

AN OVERVIEW OF SINGLE STAGE AUTOGENOUS AND

Over the years the design and operation of single stage autogenous and semi autogenous grinding mills has been a rather hit and miss affair, with some great successes and some dismal failures, with the majority of installation somewhere between. Yet the simplicity, low capital and seemingly simple operation make this a circuit of choice for many.
