Fine grinding of taconite for the liberation of iron-containing minerals is very energy-intensive. This investigation has shown that a high-pressure roll mill is significantly more energy-efficient than the traditional ball mill. Further energy efficiency can be achieved by grinding taconite in a hybrid mode, whereby the material is first ground in a high-pressure roll mill and then in a ball mill. However, optimal partitioning of energy between the two mills is necessary for attaining maximum efficiency. 10 refs., 5 figs.
