ADVANTAJES

Enables power optimization

By predicting power consumption, which is based on the characterization of the internal variables of the mill, the system recognizes the most influential factors and can correct unwanted states.

It increases the lifetime of the liners and lifters

Detection of impacts on the hull of the mill triggers a speed control, feedstock and addition of ball which seeks to gauge the angle of the waterfall in real time.

Detects undesirable operating states

By analyzing the noise level in dB mills it is possible to detect clear trends of packings and lack of mineral in SAG mills, relating high noise levels with lack of mineral and low levels with packings.
