Operating data from the single stage SAG mill at Anglo Americans El Soldado mine in Chile was evaluated and compared to four published powerbased comminution models. Case studies from literature for other single stage SAG or AG mills were then evaluated in the same four models.
Similar to the impeller design affecting pump capacity, the pulp lifter design affects the discharge capacity (or mill throughput) of AG and SAG grinding mills. Generally, the discharge from AG/SAG mills consists of one or both of the following components: slurry (water and finer particles) and pebbles (20100 mm). Single stage AG/SAG mills

Mills and GMDs, International Mining, Oct. 2010 (823 kB) Newmont''s Yanacocha mine in Peru is a single stage mill (no ball mill after the SAG mill) and has a diameter Minas Conga oxide gold copper
The Gold Mill was commissioned in March 2008 with a 32? x 32? EGL, single stage SAG mill, to process 5 million tonnes per annum high grade oxide Au/Ag ore. Operational control, feed size distribution, grinding media, mill liner, grate and pulp lifter optimisation have allowed the mill to operate 1530% above design throughput rates, but with a product P80 coarser than design.
Modifications to the existing process plant to include a single stage SAG mill, crushing and ore blending system with a nominal throughput of Mtpa. Paste fill plant and reticulation system. Dedicated portal and surface material handling and ventilation systems for the WF3 deposit. Mine
efficient, single stage SAG milling is likely to be the most profitable grinding circuit design. 2. Medium Grind 80% passing size between 106 and 75 #181;m. To mill in single stage SAG configuration, the feed must be consistent, not too coarse or too fine. The downstream process must be able to handle fluctuations in the grind size. If these
The mill will be operated as a single stage SAG mill (primary and secondary duty combined) with very high throughput made possible by the use of Outotecs patented Turbo Pulp Lifter (TPL) technology. The grinding mill will be installed during 2014 at First Quantums Kansanshi copper mine in Zambia.

INCREASING SAG MILL CAPACITY AT THE COPPER MOUNTAIN MINE THROUGH THE ADDITION OF A PRECRUSHING CIRCUIT . Dave Rose. 1; David G. Meadows2; Mike Westendorf3 . 1 Global Director, Commissioning and Optimization, FL USA Inc. .
The Mill Drives Of Copper Mountain The SAG and ball mills at Copper Mountain are the low speed version, the motors are connected directly to the pinion without a gearbox in between (the picture on the right hand side of Figure 5). Figure 7 shows one of the synchronous motors installed on Ball Mill 1.
The single stage SAG/AG milling option is ideal for starter projects with significant exploration and expansion potential. Currently a number of the largest SAG mills designed are installed in single stage configuration. This paper discusses the challenges associated with the process design of single stage SAG/AG milling circuits, the design
Difference Between Sag Mill vs Ball Mill mech4study
SAG is the abbreviated form for SemiAutogenous 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 preprocessing of any type of material in grinding process. SAG mills are also known as first stage grinders.
The apron feeders discharge on to a m wide conveyor belt which carries the ore into the mill grinding circuit. The primary grinding circuit consists of an m diameter #215; m grinding length, 5,222 kW SAG mill in closed circuit with a single deck vibrating screen and a cone crusher.
#0183;#32;Kansanshi Copper Mine. The third phase of expansion includes construction of a new 16mtpa sulphide concentrator through a single stage SemiAutogenous Grinding (SAG) mill, which can be extended up to 25mtpa by adding a ball mill in the future. This phase has been budgeted at 565m. The new Sulphide concentrator
