### Autogenous mill and semi-autogenous mill Polysius

While AG mills operate without a ball charge, SAG mills use a grinding media charge of normally 3 % 12 % for comminuting the feed material. The maximum feed size is between 200 mm and 500 mm. The AG/SAG mill is normally installed upstream of a tube mill operating in closed circuit with hydrocyclones.

### High Pressure Grinding Rolls (HPGR) SGS

This makes the use of standard ball mill analyses based on the K80 inadequate, unless appropriate corrections are made. (This problem is shared by AG/SAG mill circuits.) The most appropriate way to get around this data problem is to run the entire circuit at pilot-scale and analyze the data based on the overall power applied in kWh/t.
