By combining with SAG discharge and screening on the SAG discharge screens, topsize control to the ballmill circuit feed is maintained while still unloading the SAG circuit (Mosher et al, 2006). A variant of this method is to direct pebblecrushing circuit product to the ballmill sump for secondary milling; while convenient, this has the ...
For example, liner wear can greatly affect SAG mill performance (Toor et al., 2015) and simply including the entire historical dataset might not be optimised to predict SAG mill performance. This ...

These two types of mills are filled with varying compositions of grinding media. SAG mills contain balls of up to 150mm in diameter that occupy 5%18% of mill chamber volume. Ball mills, conversely, contain grinding media up to 50mm in diameter, occupying between 25% 40% of mill chamber volume. To effectively reduce material size, each type ...
In fact, in four of the surveys, the SAG mill was found to be more efficient at producing circuit product than the ball mill. Similar results have been seen consistently across all the surveys where this approach has been used, including circuits with AG mills, pebble mills, HPGR, stirred mills and ball mills with fine screens. Figure 2 ...
Mill in Brazil and Lumwana having a 38ft, 18 MW SAG and one 26ft, 16 MW Ball Mill in Zambia, all three mills put in operation in 2008, as well as Los Bronces, Confluencia in Chile equipped with one 40ft SAG Mill of 22 MW and two 26ft Ball Mills of MW commissioned in 2011. In the light of increasing interest in that technology various ...
In this research, in order to find a suitable range for the number of lifters in the liner of ball mills, the DEM method is utilized. Initially, a pilotscale ball mill with dimensions of m × ...

We buy, sell and consign SAG Mills of leading manufacturers like (Allis Chalmers, Dominion, Hardinge, Allis Minerals/Svedala), FL and many more. SAG 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.
SAG Mills do more than just grind, they tumble, separate, and size classify the feed through multiple size reduction steps (grate, trommel and hydrocyclone). ... SAG mills treating bauxite are often operated like ball mills, mainly on account of the soft nature of the bauxite and size of the crushed feed (< 10 cm). The actual sizes and

This allowed the ball mill to focus on coarser material while the Vertimill finished the grind on the finer material. The second Vertimill was the world's first VTM3000.
Series of batch tests were carried out to investigate different mill grinding conditions and acoustic emissions. The grinding conditions included no load, different percent ball loading (5, 8, and 10 vol%), different rock mass loading (500, 1000, and 1500 g), different water volumes (500, 1000, and 1500 ml), mixture of steel ballswater, steel ballrock, rockwater and steel ballswaterrock.
The final plan was to increase the ball charge in the SAG and ball mill to 10% v / v and 27% v / v, respectively; set the upper limit of the operating power in the ball mill to 5800 kW; use a TC Series crusher (without a power/feed ratecontrolling device, but with a feed bin) to crush pebbles for recirculation back to the SAG mill feed ...
The plus ore will be handled separately and the two will be stored in separate stockpiles. The feed to their SAG mills will be a mix of the two, the plus as media rock and the minus as rock to be ground. The ultimate product from their SAG mill will be about 6 Mesh ( mm). Further grinding will be by ball mill after magnetic separation at ...
