has been selected to design and supply a 42ft x 25ft, (12.8m x 7.6m) 28MW gearless SAG mill, plus two 26ft x 42ft, (7.9m x 12.8m) 15.6MW ball mills and two VTM-1500-WB VERTIMILLS® for Newmont Mining's Yanacocha Conga copper-gold project in Peru.
SAG mill liner development draws primarily on practical experience from SAG milling operations supported by computer-based modeling of charge motion in SAG mills and on established good design practice. Liner design needs to respond to the process aspects of mill liner action that are critical to good SAG mill performance, i.e., the impact of shell liners on the …
• SAG Mill Design Test (Starkey, 2006). There are reasonable correlations between all the tests' data that generally allow any or all of the data to be used to design a SAG mill based grinding circuit for 'typical' ores of a moderate competence range. Issues have arisen where the expected SAG mill specific energy is greater than 10 kWh/t.
Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW. Our team of product engineers continually improves SAG/AG Mill designs in order to provide the most robust, safe, and …
SAG Mill Liner Design In summary: A broad range of AG/SAG circuit configurations are in operation. Very large line plants have been designed, constructed, and operated. The circuits have demonstrated reliability, high overall availabilities, streamlined maintenance shutdowns, and efficient operation.
SAGDesign technology has become a standard for 21 st century grinding circuit design for the following reasons: Precisely measures SAG and ball mill ore hardness Fewer samples needed because composite samples are taken Testing costs minimized Assured accuracy because measurements of kWh/t are linear Grinding mill procurement timelines minimized and
The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm.
Fewer mills are, however, easier to control and capital and installation costs are lower, so the number of mills must be decided at the design stage. The high unit capacity SAG mill/ball mill circuit is dominant today and has contributed toward substantial savings in capital and operating costs, which has in turn made many low-grade, high-tonnage operations such as copper and …
Sag Mill Foundation Design Manual design of SAGballrod mill foundations. 14-3-2007 I know of one foundation that was built and then beefed up three times. The final product just became a massive block of concrete. We took one look at the foundation and permitted a modern SAG Mill to

Extrapolating designs is a lot harder and challenging than using interpolation to make a mid-size equipment. When the first 42 foot SAG mill was designed and manufactured around 2010-11, there were a lot of issues with getting such big equipment pieces fabricated and machined. The costs go up exponentially as we try to push the envelope.
mills in the older plants that had many mills in parallel In fact this is generally still the case in the multi-stream plants where mill liner design and selection is only tackled on a cost consumables basis However the gains to be had through good liner design and selection are just as great as on the large SAG mills...

The design of the 40-foot diameter SAG mill installed at the Cadia Gold Mine, New South Wales Australia, followed after two years of extensive laboratory and pilot plant testwork. This showed the Cadia ores to be hard and competent necessitating the use of both a variable speed mill drive
supported grinding mills up to the largest sizes. SAG/ball mill circuit incorporating pebble crushers and a POLYCOM® high-pressure grinding roll. SAG and ball mill for gold ore grinding. One of three SAG mills with 9.75 m diameter and 2 x 4000 kW drive power. These mills operate in conjunction with ball mills for iron ore grinding in Iran.
Another factor in good ball mill design is the relationship between Bond Wi on crushed ore vs SAG ground ore. The latter measurement is required because the ball mills in SAG plants grind SAG discharge material and the grinding test should mirror the plant flowsheet.
