SAG mills have a power higher than 10 MW. Even ball mills have a power larger than 10 MW. For this reason, they have an important impact in energy consumption and in the operation of the power distribution system. Figure 1. Picture of a typical GMD system for a SAG mill Figure 2 presents the power circuit of a cycloconverter fed synchronous motor.

To monitor and respond to critical impacts and changing conditions such as liner wear and ore variation, ECS/ ProcessExpert uses LoadIQ which is a self-powered smart sensor attached to the mill shell. Conditions inside your mill are automatically adjusted to minimise liner damage, stabilise and then optimise the operation of a SAG Mill.
