The one sound operators do not want to hear is the sound of the mills standing still. A gold-processing plant, I visited recently valued their SAG mill downtime at US$ 130,000 per hour, so extending the life and availability of mill liners is crucial to them. The …
study is a SAG mill open circuit composed of an ore feeder, water control v alve, and mill depicted in Figure 2. The SAG mill model is based on a differential equation. …
Control sag mill sound detection grinding.Grinding amp classification circuits where i work now minera san cristobal in bolivia we use sound control on both the sag and ball mills the result of this control is a 25 increase in throughput over the plant design with a 10 reduction in energy consumption the mill is more efficient view the.
The inferential models could be utilised in a SAG mill load control strategy, as a measure of SAG mill performance, as an indication of the primary grinding circuit operating conditions, or, any ...
Therefore the plant took the sound reading as an indicator of changes in SAG load for milling circuit control. Other systems adjust mill speed in response to acoustic information to control the mill load and ensure maximum grinding efficiency by moving the point …

The modeling and simulation of semiautogenous (SAG) mills have been widely used in the design and optimization of mill performance in terms of its power draw, processing capacity and product size distribution. However, these models are solved under steady approximation and do not provide any information on mill charge distribution in real time. This paper attempts to characterize mill contents ...
The idea was that we could use sound to see how full the mill was based on the sound emitted by the SAG mill. Ignoring the shortcoming that a sound sensor does not …
SAG mill #1 load control Plant staff, after extended testing and rigourous data analysis, determined that BrainWave reduced load variability by 14% while increasing production by 1.5%. This was a great success for everyone involved. Assuming a copper price of 4 USD/lb, ANDRITZ AUTOMATION estimates that BrainWave SAG mill led to an extra 12M USD
As part of its SAG mill control system, Manta Controls developed the Manta Mic: a robust and reliable acoustic analyser that prevents mill damage. 18 Tips - Successful Sound Measurements Conducting sound measurements requires a sound level meter of course, but the sound level meter itself is only one of the many things you need to remember when ...
Control of -SemiAutogenous Grinding(SAG) mill weight is an example of an important process that exhibits many of these aspects. Maintaining the SAG mill weight at the optimum value is critical for achieving maximum grind rate efficiency and mill production (Powell, M.S., van der Westhuizen, A.P., & Mainza, A.N. 2009).

Therefore the SAG mill speed could not be controlled using the microphone based signal and instead was manually controlled/set by the control room operator. Thus operation/speed of the mill could and would change significantly based on a particular operator running the mill and their overall level of mill operation experience and skill.
The Manta Controls Advanced Control System, called the SAG Cube, automatically monitors and controls a SAG Mill, keeping track of critical process variables impacting mill throughput. For most sites, one hour of operation provides a revenue between AUD$ 20,000 per hour up to …
An industrial example of its use is for the problem of SAG mill feed rate control, shown in Figure 12, which is notoriously difficult for a PID controller due to the …
