Considering the continuous increase in production costs and resource optimization, more than a strategic objective has become imperative in the copper mining industry. In the search to improve the efficiency in the use of resources, the present work develops models of a semiautogenous grinding (SAG) mill using statistical analysis and machine learning (ML) techniques (regression, decision ...

The three gearless mill drive (GMD) systems are the ABB most powerful ever made. The GMD for the 40foot SAG mill has a power rating of 28 megawatts (MW), and the GMDs for the two 28foot ball mills have a power rating of 22 MW. They are the largest diameter and most powerful SAG and ball mills drive systems at the highest altitude installed to ...
Principle of SAG Mill operation SAG mill. SAG is an acronym for semiautogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' () in diameter, powered by a 28 MW (38,000 HP ...
The singlestage autogenous grinding (AG) or semiautogenous grinding (SAG) mill is a lowcost option for milling relatively low tonnages.
The Copper Mountain Mine is located approximately 20 km south of Princeton, British Columbia, Canada (refer to Figure 1). The region has a long history of copper mining dating back to 1923. The Copper Mountain camp occurs in the 'eastern volcanic belt' of the Nicola Group (Monger, 1989). It is an alkali

The singlestage closed ROM ore milling circuit considered in this study is shown in Fig. 2 and constitute a SAG mill with an enddischarge grate, a sump and a hydrocyclone. The mill receives four streams as inputs: mined ore, water to assist with material transport, steel balls to assist with ore breakage, and under ow from the hydrocyclone.
Runofmine ore is direct fed by 77 Mt (85 st) haul trucks, or is stockpiled and blended by front end loader, to maintain specified limits for sulphide and cyanide soluble copper content. Primary crushing is accomplished with a single stage m x m (48 in x 60 in) FullerTraylor jaw crusher.

The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to m. Product: 300mm (for transport) to 200mm (for SAG mill) Feed Rate:
This research is focused on the Phase I SABC milling circuit of the Wushan porphyry copper mine. Improvements to the existing circuit were targeted without any significant alterations to existing equipment or the SABC circuit. ... Atasoy, Y.; Price, J.

These mills typically grind ROM ore in a single stage. A large example of such a mill was converted from a singlestage milling application to a semiautogenousballmillcrushing (SABC) circuit, and the application is well described (Mainza et al., 2012). This section refers to highaspect AG/SAG mills.
