GET PRICEIn the case of autogenous (AG) and semi-autogenous (SAG) mills this has provided a significant challenge to modellers, due in part to the interaction between feed characteristics and mill performance and also due to the difficulty in obtaining high quality relevant data from full-scale circuits. As a result the literature contains numerous papers on AG/SAG mill modelling, the majority of which

GET PRICESemi-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.

GET PRICESAG Mill. Semi autogenous grinding (SAG)technology, as an effective measure to reduce the capital investment and production cost, has been widely recognized. It has been widely applied in non-metal mineral processing, ferrous metal mineral processing and non-ferrous metal mineral processing, and is being popularized gradually in gold processing plant. Application in CIL Plant. SAG mill can be
