Drying and Roasting Characteristics of Iron Ore Pellets with

Drying and roasting behavior of iron ore pellets with microwave and conventional heating have been comparably investigated The results showed that the dehydration time of green pellets can be shortened by approximately two thirds with microwave heating Meanwhile the average compressive strength of pellets with organic binders dried by

Heat Transfer Conditions in Hydrogen Fired

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
