A tool with a low flute count (2 to 3) has larger flute valleys and a smaller core. As with LOC, the less substrate remaining on a cutting tool, the weaker and less rigid it is. A tool with a high flute count (5 or higher) naturally has a larger core. However, high flute counts are not always better.

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.
