The number of SAG mill revolutions required to grind the material to a P 80 of 1.7 mm is used to predict AG/SAG specific energy using quation 4. Correction E factors for feed size and pebble ing are applied to the AG/SAG specific energy, as well as specific crush energy adjustment from 1.7 mm to the mill transfer size T 80 using Bond's Law (Starkey & Larbi, 2012). The Bond equation is used ...

FL has just launched a new SAG mill liner protection solution called SAGwise™ total process control, with an estimate of less than six months ROI. It has been shown in tests that it can reduce damage to the liners by over 40%. FL told IM: "Extending the life and availability of mill
The objective is to develop preliminary cause and effect relationships that provide the foundation for a computer based control strategy for maximizing, or optimizing in the case of a fixed tonnage operation, SAG mill throughput.
MODIFYING THE MILL FEED SIZE DISTRIBUTION The SAG milling of ores with high levels of competency leads to high SAG mill specific power consumption and a high proportion of very fine SAG mill product. The technique was pioneered and developed at Kidston Gold Mine. Henderson and Putland (1996) reported a classification as "high competency" for rocks that exhibit relatively uniform …
The SAG mill is 26' diameter x 12'3" EGL and powered by 4,500 HP motor driven by a variable speed LCI drive that can control the mill speed from 36% to 80% of critical speed depending on ore type and operational demands.

The optimal performance of AG/SAG mills is the key to successful plant operation. All AG/SAG mills using radial or curved pulp lifters suffer from inherent material transport problems such as ...
SAG Mill - Ender IO Wiki. The SAG Mill is a machine that grinds items down into other items It draws without upgrades 20RF/t and takes about 10 seconds to complete an operation It will produce extra materials depending on what you put into it, for example .
Pueblo Viejo installed a SmartEar™ to monitor the acoustic emissions of their SAG mill in January 2013. This system has been installed on many mills around the world and is specifically designed for optimising SAG mill control. One system output is the impact counter which measures steel-on-steel impacts on the mill shell. The impact counter uses both frequency and time domain …
Video 1: Mill Showing Surface Wear Modification Case scenario. Consider a large SAG mill with a diameter of 10.97 m, as shown in Figure 1a. The mill has a high-definition line design with alternating lines of high and low elevators (Figure 1b).

There is a type of plant where the constant throughput SAG mill is sensible. If the SAG mill is not intended to be the rate-limiting step in a process plant, then it is best to adjust the SAG load (and power) to hold a constant tonnage to satisfy another constraint elsewhere.
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 TRIO TC Series crusher (without a power-/feed rate–controlling device, but with a feed bin) to crush pebbles for recirculation back to the SAG mill feed; and change the number of pebble ports in the SAG ...
