Introduction to Iron ore Pellets and Pelletizing processes

It is an agglomerating process of converting iron ore fines into uniformed sized iron ore pellets which can be charged directly into a blast furnace (BF) or into a vertical furnace or rotary kiln normally used for the production of direct reduced iron (DRI). The iron ore pellets are shown in Fig 1.

Modeling and simulation of iron ore pellet drying and

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.
