Abstract：The kinetics model of roller press comminution was suggested by consulting manyreference materials and theortical analysis. The two important parameters of the model, i.e. selective function and distribrtion function, were obtained, based on a lot of experiments on the smallroller. The particle size distribution of products of roller was predicted successfully with the kinet-ics model by computer treatment.
