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

Outotec MillSense mill charge sensor system - .

The mill charge volume has a great impact on grinding efficiency. For efficient grinding, autogenous (AG) and semi-autogenous (SAG) mills need to be operated with the correct charge in order to maximize their throughput while avoiding overloading. The Outotec MillSense sensor system gives a precise indication of the mill charge volume.

Overloading tends to accumulate fines at the toe of the mill which results in a cushioning effect. When the rock load is low, excessive ball-to-ball contact retards the rate of breakage. The fraction of mill volume occupied by the ore, J↓R: J↓R=M↓R / ρ↓S / V↓M x1 / .

Mill Bolting

The mill manufacturer specifies a load which is designed to be the optimum load applied to the bolts to hold the mill together for its entire life, which can be in excess of 20 years, some mill manufacturers specify an elongation, unfortunately they usually specify a torque figure which should in a best case produce the correct elongation, but rarely does.

SAG mills are a key asset for mineral processing operations as one of the critical stages of extracting mineral out of ore, and their continued stable operation is central to productivity. However, the performance of a SAG mill changes rapidly in response to conditions such as feed size and hardness as well as longer-term variability due to liner wear – something no instrumentation can ...

Overload Model | IntelliSense.io

The overload prediction model is a real-time model that, every minute, outputs the estimated probability of an imminent or active overload happening in the SAG mill. The minute-wise prediction means that the model is not identifying isolated overload events, but rather gives a constant stream of estimates for the classification that it was trained on.
