Maintaining the work balancebetween the primary SAG mill and secondary ball mill(s) is an overlooked bottleneck, and thus opportunity, in an increasing number of circuits worldwide. As circuit capacities are expanded by 'releasing' the SAG mill bottleneck, the work is progressively passed on to the downstream ball mills.
such as FL's SAGwise system, which uses an array of sensors to listen to the sounds of a rotating mill for indications of over- or underloading; or Outotec's MillMapper, which gives operators a quick virtual look inside the mill to assess liner wear without stopping production.

Detecting the onset of overloading in a semi-autogenous grinding (SAG) mill is a challenging task for operators to perform due to the complex and nonlinear nature of an overload. To detect an overload, operators must simultaneously monitor the correlations between several measurements of the SAG process.
SAG Mill Control Instability: Causes and Solutions. Oscillatory unstable behaviour in a SAG mill is characterised by the mill constantly cycling between an overload condition and recovery from that condition by a substantial reduction in feed rate tonnes. Such behaviour is commonplace with SAG mills and gives rise to a significant overall ...

with overload detection because of the process nonlineari ty. Recently, locally linear embedding (LLE) with a linear classifier has been proposed to detect the early onset of an overload in a SAG mill . In this paper, we compare the suitability of LLE to detect the early onset of an overload against kernel PCA and support vector machines.

Newcrest Sag Mill Overload Downtime Prevention At Lihir The Lihir mill FORESTALL overload algorithms were developed using an engineered approach to data science. For example in this case, engineering knowledge was used to create an additional 650 engineered signals from the original 143 raw signals for each SAG mill about 800 signals per mill.
There was a huge amount of data that comes off a SAG mill – noise was recorded, power, speed, energy consumption and control parameters – there were hundreds of measurements, usually taken at five-second intervals that needed to be analysed. The Lihir mill FORESTALL overload algorithms were developed using an engineered approach to data science.
& Mainza, A.N. 2009). However, SAG mill weight is difficult to control as the dynamic response changes as the mill approaches maximum capacity. Near maximum capacity, the weight response exhibits integrating behavior, and the mill can overload quickly. This situation is complicated by the transport
Grinding Mill Charge Detection Sensors. 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 …
Another common issue with SAG mills is operating at very low density (e.g. <70% solids) - if there is room to increase SAG density, this will enable the SAG to grind finer with little or no decrease in throughput. Consider reducing the feed rate when the overload starts rather than waiting until a grind-out becomes necessary.

SAG mills have a higher installed power density for a given plant footprint relative to AC mills. With the combination of finer grind and a lower installed power density (based on the lower density of the mill charge), a typical AG mill has a lower throughput, a lower power draw, and produces a finer grind.

SAG mill make use of steel balls included with some large and hard rocks for grinding. These mills utilize the balls in making the large fragments of materials broken into pieces. The ball charge of a SAG mill is about 9% to 20%.This process takes place inside the large rotating drum of SAG mill which is filled with balls partially.
