mill diameter, mill length, grates openings, and pebble ports size; the power equation is also function of all the operational variables selected for this study. The applied force is a function of the mass inside the mill and it is composed of balls, ore and water. The ball charge is a function of the bulk fraction of the SAG mill volume (Jb)
The discharge grates of the SAG mill were identified as a key component in the SABC circuit, and their design is a crucial factor in the mill's performance [17,18,19,20,21]. The initial design of the grate section caused a serious accumulation of pebbles within the SAG mill which contributed to a decreased grinding efficiency.

SAG mill. SAG is an acronym for semi-autogenous 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' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.

AG/SAG mill and crusher circuit simulations through the use of JKSimMet. Independent of this it can be used in power-based calculations, which in conjunction with the Bond ball work index test, enable the prediction of the specific energy of comminution circuits where such circuits include combinations of any of the following equipment:
The SAG Power Index (SPI) test (Starkey & Dobby, 1996) uses a benchscale SAG mill test to - determine the specific energy of an industrial SAG mill. The test is operated in closed circuit and the time required to grind the material to a P 80 of 1.7 mm is used to predict AG/SAG specific energy using Equation

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. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

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). The mill processes rocks from 200 mm to 300 mm, using 350 mm steel balls as the grinding medium.

W Total = WSAG + W Ball Mill (2) Where W is the grinding mill work input in kWh/t. For the above reason, the Starkey SAG mill was built in 1991 to measure the energy required to grind ore to a size of 80% passing 10-mesh or 0.17 mm (T80) by grinding small drill core samples to precisely that size.
Some design methods (Lane et al., 2013, Morrell, 2004, Siddall & Putland, 2007 predict the total comminution energy requirements of SAG mill-based circuits using work indices measured in ...
Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW.
