Optimized Operations. Sensor-based ore particle sorting can be used to pre-concentrate ROM ore feed, SAG Mill scats and low grade or waste stockpiles. Plant throughput increase, reduced operating costs and mine optimization should be considered in evaluating sorting as well as increased recovery in flotation and leach circuits.

An optimization is carried out to minimize the yearly cost of energy for the operation of the SAG mill. This cost includes the energy consumption cost in $/kWh and the capital cost for the PV-BESS infrastructure, prorated over the life of the battery system, accounting for the discount rate through an annuity factor (Pamparana et al. 2019a, b).The energy requirements are defined by the SAG ...

The operation of AG/SAG mills is sensitive to mill filling, therefore developing grindcurves to relate mill filling to performance indicators such as throughput, power draw, and product size can assist in achieving optimal mill operations. The throughput, power draw, and product size have been shown to peak at different mill filling levels.

The SAG data corresponds to the operation of three mills over six months, from which a typical day was selected through fuzzy c-means clustering. The total production for this typical day was 192,000 tons for the three SAG mills, with a maximum and minimum SAG mill power consumption of 42.17 MW and 40.77 MW, respectively.

For SAG Milling, optimizing the throw and converting the available electrical energy (installed motor power) to potential energy (height of throw, trajectory) to kinetic energy (rock breakage) is the key function. Therefore, having a speed range available allows this tuning of the SAG mill.

Optimizing your SAG mill operation - International . As a result, mines have shifted their emphasis in optimization from ball mills to SAG mills. The rock load in the mill essentially depends on ore characteristics and the discharge rate of broken particles through the discharge end.

In the first part of this work, a solar photovoltaic system with battery storage (PV-BESS) and grid backup system to supply a SAG mill was modeled. There, the overall framework, the optimization model, and the model for the solar forecast were presented. Here, in the second part, the impact of ore hardness variability and uncertainty is studied.

SAG mill operation is "sensitive" to changes in ore quality (hardness and size). Changes in the feed can quickly result in a build up, or loss, of rocks inside the mill. Both situations result in undesirable conditions for the mill. Getting real-time knowledge of what is going on …

SAG Mill Discharge. Controlling the feed and discharge of a mill is mostly a stabilisation exercise – you need to be able to quickly and accurately control the mill feed rate. If the mill feed setpoint is changed, then the actual feed rate needs to stabilise at the new target in a short period of time. The feed rate setpoint can then be tied ...

The 'automated' approach: Modeling out your operations.

Relative to other comminution machines in the primary role. SAG mill operation is more dynamic, and typically requires a higher degree of process control sophistication. Though more complex in AG/ SAG circuits relative to the crushing plants they have largely replaced, these issues are well understood in contemporary applications.

Protecting and Optimizing Mills The main benefits of this type of reliable SAG mill monitoring are accurate and repeatable decibel signals at the various frequencies – information that is used to protect the mills. The next phase of the project is to provide measurements that can help customers operate a SAG or AG mill optimally.

Optimising the capacity of your SAG mill is crucial to avoiding downtime and liner wear and damage. With variances in mill ore feed rate, mill speed and slurry density, critical impacts can occur in your SAG mill. The speed at which these variances are adjusted for is thus crucial for minimizing damage and optimizing liner life.

This allowed them to reduce the SAG mill media size and operate at a slower speed without the rock load building and destabilising the mill. In turn, this provided spare mill capacity which can be used to assist the ball mill. One of SRK's recommendations under consideration is returning a portion of the cyclone underflow back to the SAG mill.
