White paper, September 2015 SmartMill™: Exceed your,

If the ore is too hard or abrasive, a small charge of steel balls may be added to aid the process — the mill is then called a semi-autogenous (SAG) mill. AG/SAG mills are often used as the first stage in a two- or multiple-stage grinding process, where the second stage is carried out by,Mill application features control.Autogenous and Semi-Autogenous Mills,in a 6 ft. batch mill, can be conclusive if the ore resembles ore previously tested. The third, and most precise, level of testing involves continuous milling in a 6 ft. x 2 ft. AG/SAG mill. Up to 50 ton samples are required for each ore type to be tested. The results of,with circuit and circuit control design as well as start-up, operation,Autogenous and Semiautogenous mills - Metso,AG/SAG mills can accomplish the same size reduction work as two or stages of crushing and screening, a rod mill, and some or all of the work done by a ball mill. All because of the range of mill sizes available, AG/SAG milling extends itself to many applications.
