2018-1-17 · ABSTRACT. Drying is a critical process step to achieve excellent pellet quality in pelletizing process. The complexity and energy consumption toward moisture removing, especially for highly hydrated iron ore, increased the need for breakthroughWe 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.Modeling and simulation of iron ore pellet drying andIn the present method of drying iron ore pellets, e.g., magnetite pellets, moisture-containing iron ore pellets are formed into a bed comprising a multiplicity of the pellets. A current of drying gas is forced upwardly through the bed of pellets to at least partially dry some of the pellets.
