MILLING CONTROL OPTIMISATIONMINTEK

MILL FEED CONTROL. Smooth operation of a milling circuit is difficult to achieve due to • The varying nature of the feed material (size ore hardness etc.). • The unfavorable dynamics between feeders and the weightometer. These dynamics degrade the performance of PID controllers making feed optimisation more challenging.
