Modeling and simulation of iron ore pellet drying and

2012-5-25  Abstract: 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.

Convective drying of an individual iron ore pellet

2011-8-1  Drying of an individual iron ore pellet is here modeled numerically with the aim to clarify the different stages of drying. With estimations of the permeability of K = 2.501e−14 m 2 and the interstitial heat transfer coefficient set to h sf = 0.55 W m −2 K −1,simulations of a scanned pellet show very good agreement with experimental
