mills. The mills in mining operation grind the product from the crushers to fine material ready for treatment. Rod mills, ball mills, autogenous mills, and semi-autogenous mills (SAG Mills) all have a number of lubricating and hydraulic systems, and they must work to keep mineral output high.

With SAG mills, the response is typically that for coarser ores, throughput declines, and vice versa. However, for AG mills, there are number of case histories where mills failed to consistently meet throughput targets due to a lack of coarse media.

Thus, with condition monitoring of the SAG mill behaviors employing vibration, acoustic and thermal signals, the relevant parameter can be diagnosed and monitored. Accordingly, the mill may work on its optimum conditions without the concern of any imminent problem like mill congestions and unplanned stops.

SAG and Ball mills at an ore processing facility – typically the mill drives, the mill gearbox and mill bearings are monitored. Loss of one SAG mill could result in a significant production shortfall. In addition, an online monitoring system should be able to deliver data in whatever format is required for analysis, such as:

Given that the SAG mill often shows up as one of the last milling processes, shutting down or running half-empty just because stockpiles got too low is expensive. Ore size also has an impact on the comminution circuit, in terms of wear and tear on equipment.

The SKF IMx-S condition monitoring system was set up and configured with appropriate alarm thresholds. After monitoring the SAG mill for just under three months, warning signs appeared in the data. An analysis of a waterfall diagram showed that sidebands had developed around the input pinion gear frequency, indicative of the wear on the gears.

Therefore, the decision was made to install a permanent on-line monitoring system on the SAG mill. We installed a monitoring system called KITE. It can manage various conditions and measure at different load speeds and in different directions. The mill is a fixed-speed machine, so we didn't need any special inputs.

Surface vibration (acoustic emissions) monitoring is a noninvasive low-cost means of monitoring normally inaccessible attributes of processes or equipment operation. The current investigation monitors vibrations in a SAG mill by an accelerometer attached to the outside of …

In other words, condition monitoring. This approach results in corrective maintenance only when. the condition indicates the asset is failing. Further, failure progression can often be trended quite accurately, allowing maintenance intervention at exactly the right time—not too soon, not too late.

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball …

Condition Monitoring Condition monitoring is a process where the condition of equipment is monitored for early signs of deterioration so that the maintenance activity can be better planned, reducing down time and costs. This is particularly important in continuous process plants, where failure and downtime can be extremely costly.

SAG mill and how the vibration response and hence mill operating conditions vary as a function of time, including during mill equipment failures such as a broken discharge grate. Opportunities for improved mill control based on the data from the on-line monitor are also discussed, as well as the implications in terms of mill processing and

The SCU uses the latest technology in high-definition imagery within a custom designed housing, permanently affixed to the feed chute to provide a live audio and temperature feed in a running SAG mill and video feed from inside a stationary SAG mill. This enables remote monitoring of the condition of the shell and discharge liners and mill charge.

With the increase of mill motor capacity to 4.2 MW (megawatt), momentary power limitations and throughput restrictions caused by changing ore hardness in the mill are eliminated. The online condition monitoring system will allow OTML to track mechanical wear and assist with proactive maintenance.

Beyond conveyors, continuous condition monitoring can improve performance for electric shovels, chute automation, SAG and ball mill automation, and mill circuit isolation. For electric shovels, Industrial Internet of Things (IIoT)-based wireless vibration sensors detect problems in transmission, motor unbalance, bearing failure and in propel ...
