The semi & autogenous mill is often operated in closed circuit with a trommel screen or external vibrating screen classifying the discharge. Circulating loads are low compared with those in ball mill circuits, because autogenous mills do not benefit from high-circulating loads in the same way ball mills .

Autogenous Grinding Circuits. When an ore is hard and competent, there is always the possibility that it would make good "pebbles" which could be used for fine grinding media. Different methods that have been tried using combinations of autogenous, semi-autogenous, pebble and/or ball mills. The flowsheets shown are typical of the properties ...

If semi-autogenous grinding is indicated, the source for, and cost of, obtaining high quality balls in the 100 mm to 125 mm size range should be reviewed. The grinding balls used in semi-autogenous mills must be of top quality so that they will not break from the impact forces encountered in primary semi-autogenous mills.

Oct 12, 2017· SAG is the abbreviated form for Semi-Autogenous Grinding Mill. This type of Mill is used for grinding large fragments into small pieces. Pieces are then used for further processing. The SAG mills are generally used in pre-processing of any type of material in grinding process. SAG mills are also known as first stage grinders.

Rely on our proven track record of SAG and AG Mill superiority. Since the early 1980s, we have been designing and manufacturing Semi-Autogenous (SAG) and Autogenous (AG) Grinding Mills under the Fuller-Traylor brand. Semi-autogenous grinding uses a minimal ball charge in the range of 6-15% while autogenous grinding uses ore only.
