Wet comminution kinetics of dolomite at laboratory scale
Wet comminution tests of discretized dolomite sample were conducted in planetary ball mill and reported in this work. The effect of ball diameter and feed size on the comminution kinetics was investigated. Literature models were used in attempt to provide adequate selection function estimation. Rajamani and Herbst model was proposed for evaluation of the selection functions (S-j) in planetary ball Mill under given process conditions. Model parameters were correlated to ball diameters. The methodology suggested in this paper can provide assessment of model parameters and consequently Sj parameters. This work represents a good foundation for further quantification of interactions in the comminution processes, and thus the prediction possibility of product properties in various process units and process conditions.
