Milling Control Optimisation
ore treated was very difficult to mill. In the first two days, the mill experienced numerous power dips (overloads), and on at least seven occasions the feed to the mill had to be completely stopped to grind the mill out. Also, the mill load varied in the range of 125 to 165 tons. These disturbances propagated throughout the milling circuit and ...

iron ore. His process involved grinding taconite to remove gangues and upgrading the iron ore (i.e., an ore beneficiation process). The resultant high-grade ore is in the form of fine particles, as small as 0.1mm or less, which are not suitable for sintering. This issue led to the use of pelletizing. Pelletizing plants are expected to play an
