Modeling and simulation of iron ore pellet drying and induration process

We present a mathematical model of iron ore pellet drying and induration in an industrial scale application, and validate it against measured data. The model is based on the laws of mass and heat transfer, and incorporates both physical and chemical processes. The partial differential equations of the process kinetic model involve derivatives in time and bed depth. The model can provide an effective tool for the analysis and design of iron ore pellet induration techniques.
