Improving Energy Efficiency Via Optimized Charge Motion

2021. 4. 4. Now the power consumption is 0.3-1.3 kWh/ton lower than before. The actual SAG mill power draw is 230-370 kW lower. Mill runs 1 rpm lesser in speed on the average. The recirculation to the cone crusher is reduced by 1-10%, which means more efficient grinding of critical size material is taking place in the mill.

Improving Energy Efficiency Via Optimized Charge Motion

A research team from the University of Utah is working to make inroads into saving energy in these SAG mills. In 2003, Industries of the Future Program of the Department of Energy tasked the University of Utah team to build a partnership between the University and the mining industry for the specific purpose of reducing energy consumption in SAG mills.

Optimizing your SAG mill operation International Mining

2021. 4. 4. As the ‘heart of the plant’ could be viewed as the milling/grinding area, one of the key steps in plant optimization is ensuring the mill is operating properly. In the past, when primary, secondary and tertiary crushers fed material directly to large ball mills, the energy efficiency of the concentrator was determined for the most part by the ball mill operation, whereas now the energy efficiency of a plant often rests largely on the SAG mill

2019. 10. 9. plot will still be created. The mill speed did not have an effect on grinding energy efficiency and it was found to be a reliable indicator of net mill power draw between 1400 and 2000 RPM, as shown in Figure 1. Less residence time was required to grind to a given target size as the mill speed was increased.

Modelling SAG milling power and specific energy

In the first model (power equation) the average error obtained was 3.7% and in the second model (specific energy) the average error was 6.8%. These models would be useful for performance optimisation of the test case mills and should be fitted (parameters values) again for other mills.

2021. 3. 16. The new Aitik autogenous grinding (AG) milling circuit was based on the successful original milling plant at Aitik, with a focus on low life-of-mine operating costs. At the heart of this is eliminating steel grinding media, maximizing the use of gravity flow, and using spiral classifiers instead of hydrocyclones.

This plant, constructed in 2001/2002, and having a production capacity of 300,000 tonnes per year, had already been constructed in a highly energy-efficient way. A multi-stage grinding system using two-pass crushing mills and vertical-rotor hammer mills reduce the energy requirements by about 30% compared to a direct grinding system.
