Volume Title: 12th Mill Operators' Conference 2014 Semi-autogenous grinding (SAG) mill control is complex and depends on many dynamic process variables. Good control strategies ensure that a mill is operating as close to optimal as possible, resulting in significant economic benefits to an operation.
Abstract: One very important charge condition that can produce a catastrophic failure during the starting of grinding mills is the compacting of the load inside the mill, especially after long downtimes. This condition is usually named frozen load and the load remains locked to the mill shell and after a half turn drops damaging the mill body and bearings.

Typically, a SAG mill based circuit (P80 of 106 to 150 um) has media costs of around A$1/t. Providing the ore is amenable, the use of primary autogenous milling can reduce this cost by 40%. Autogenous milling is typically practiced in association with .
In semi-autogenous grinding (SAG), the grinding mill inventory, (i.e. volume of total charge, volume of ball charge, etc.) is important in determining the SAG mill ball charge determination and its influence on mill drive requirements - IEEE Conference Publication
The circuit consists of a 34' x 20' EGL SAG mill, a Raptor 900 pebble crusher and two 24' x 39'6" ball mills. Each mill is equipped with a 2 x 8500 HP dual pinion drive system. The plant was designed to process 1585 mtph of SAG feed. From startup, the mill struggled to meet the required production rates.
As SAG milling matures in the industry, the conference has moved with it resulting in a more diversified focus, including a lot of operating HPGR project data and for the first time fine grinding. The data on operating SAG circuits, historically a key feature of this conference, was somewhat diluted compared to previous conferences as a result.
