20191012&ensp·&enspSAG is an acronym for SemiAutogenous Grinding. SAG mills are essentially autogenous mills, but utilize grinding balls to aid in grinding like in a ball mill. A SAG mill is generally used as a primary or first stage grinding solution. Attrition between grinding balls and ore particles causes grinding of

Semiautogenous grinding (SAG) and autogenous grinding mills are used for grinding large chunks of materials into smaller pieces which can be later used for processing. Such mills are used in the primary stage of grinding process where pieces of raw materials

Crushing and grinding usually require the greatest portion of capital costs and often make up 6070 percent of total mill operating costs as shown in Figure 1.

Hence, the design optimisation of pulp lifters affects not only the energy efficiency and throughput of autogenous grinding/semiautogenous (AG/SAG) grinding mills, but also contributes other process benefits such as improved wear life and operatorfriendly steady and smooth mill operation.

Grinding takes place in more "open" space which makes the retention time longer and adjustable compared to crushers.

By opposition, the JKMRC approach to autogenous mill characterisation was to separate impact and abrasion mechanisms into two different tests (dropweight and abrasion tests). Equally important is the need to

20191011&ensp·&enspAutogenous grinding implies by definition the grinding of ore by itself. Autogenous mills can be operated in tandem with secondary grinding mills (either a ball or a pebble mill) or they can be operated as singlestage mills in closedcircuit with a classifiion or sizing device.

This progression has, not necessarily, been accompanied by an improvement in the efficiency of power utilisation in achieving the target grind size, but has seen an improvement in the overall efficiency of mineral processing as
