Show 7.Conclusions The simulation model is based on the first-order breakage law, the primary and secondary classification parameters, the variation of scale-up factor with make-up feed rate and mill conditions, and the mass transport relation of particles through the mill. The model can be used to predict the behaviors of the ring-roller mill systems. 8.References 1) L.G.Austin et al.,Powder Technol., 29 (1981) 263-275. 2) L.G.Austin et al.,Powder Technol., 33 (1982) 113-125. 3) L.G.Austin et al.,Powder Technol., 33 (1982) 127-134. 4) N.
