    Artificial intelligence applied to mill optimization

    Feb 10, 2021 The grinding mill was processing ores of variable size, shape, hardness, etc., and had to be controlled to mitigate the possibility of ore build-up inside the mill and subsequent overload or runaway conditions. In fact, this dynamic variability of ore-feed along with other process uncertainties soon created a bottleneck of automated control ...

    Inside these SagBall mill are big steel balls that grind ore via an impact process. In simple terms, these hard metal steel balls get to the top of the rotating chamber and fall down crushing the ore being processed. It grinds it up into a compound to make processing easier. Youll find a similar process in sugar cane mills.
