The iron ore was obtained from British Steel Ltd and in this paper is described according to its major iron oxide component, magnetite. The magnetite iron ore was crushed in 30-min increments using a planetary mono ball mill, Fritsch Pulverisette 7, operating at 300 rpm. The grinding vessel and balls were fabricated from zirconium oxide.

The present work analyzes the application of the UFRJ mechanistic ball mill model to grinding of iron ore pellet feed in an industrial grinding circuit.
