Jan 01, 2016· The SAG mill had a 6–8% ball charge and the power consumption was 8 kWh/t, which agreed well with the expected value. 9.6. Problems. 9.1. In an SAG mill the dimensions of the mill were 9.75 m × 3.5 m and the specific gravities of the mineral and …

Breaking down energy consumption in industrial grinding mills

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 gold ores feasible. Future circuits may see increasing use of high pressure grinding rolls (Rosas et al., 2012).

Modelling SAG milling power and specific energy ...

Example Ball Mill GrindingExpert ™Solution The throughput and efficiency of a SAG mill depends on the volumetric load: An overloaded mill has reduced coarse ore breakage, as the cascading balls and rock cannot drop far enough, reducing kinetic energy for breakage. An underloaded mill will break coarse ore well, but at the expense of added

Modelling SAG milling power and specific energy ...

Oct 15, 2020· The order comprises a 22-foot diameter by 8-foot effective grinding length(egl) SAG mill and 14.5-foot diameter by 19.5-foot effective grinding length ball mill. Both mills will be driven by 2000 KW, low speed synchronous motors at 78% critical speed.

Reduce ball consumption Minimise downtime Get the full return on your investment in under six months Challenging as SAG mill management may be, the fact remains: your plant's productivity relies in large part on your ability to maximise the SAG mill's availability rate – and to preserve and extend liner life.

(Received: February 1, 2016; Accepted: November 4, 2016)

The pilot mill is also equipped with a sensor measuring the 'ball and pulp toe and shoulder angles' (see Figure 3). These data are then used to calculate the total pulp and ball charge angle (see Graph 5). Graph 5 clearly illustrates how the ball charge stays quite compact till about 73% solids as the total media angle does not change.

What's the Difference Between SAG Mill and Ball Mill ...

Dec 18, 2013· In contrast to laboratory-scale testing for ball mills and AG/SAG mills, test work results for stirred mills can be used for sizing full-size equipment with a scale-up factor close to one. Larson et al .[ 19, 20 ] found a scale-up factor for the Isamill of exactly 1, while Gao et al .[ 8 ] imply that the scale-up factor for SMDs is 1.25.

ball consumption in iron ore sag milling

SAG mills grinding media includes some large and hard rocks, filled rate of 9% – 20%. SAG mill grind ores through impact, attrition, abrasion forces. In practice, for a given ore and equal processing conditions, the AG milling has a finer grind than SAG mills.

mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential ...

Benchmarking: Specific Energy Consumption Models ...

ball consumption in sag mill. 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. how to calculate the energy consumption of a ball mill

Selection of Comminution Circuits for Improved Efficiency

SAG mill balls experience both significant abrasive and impact wear due to their large (75 – 100 mm) diameters. Ball mill balls experience a greater number of impacts, but at lower magnitude than SAG mill balls, due to the smaller ball size, and smaller mill diameter. Feeds are typically highly abrasive,
