Abstract
A two dimensional, discrete element method computer program has been constructed to predict
grinding media motion in a planetary ball mill. Various impact models have been assessed for
suitability to simulate actual milling impacts. They include Kelvin and Maxwell viscoelastic models
and an elastic/plastic yield model. The computer simulation has then been used to consider
variations in processing parameters such as impact frequency and energy associated with different
milling configurations. These results have then been compared to the kinetics of the CuO/Ni
displacement reaction propagated under these conditions.
