This paper presents the results of an investigation of a full-scale rod mill. Appropriate numerical techniques are developed for the experimental determination of the parameters of a dynamic mathematical model from steadystate data. The results confirm that this full-scale rod mill behaves similarly to laboratory-scale ball mills for which results have previously been obtained. It is noted, however, that although the model presented is adequate for predicting over-all particle size distributions, the size distributions of individual components of a multicomponent ore cannot be predicted.
