Induration Process Model Results. As examples of the model output, results generated with the straight-grate and grate-kiln-cooler pelletising process configurations of the induration model component are presented below.
To explore the possibility of successfully processing iron ore pellets with a high content of hematite, thermogravimetric tests were performed to study the induration process of pellets composed of a mixture of iron ore concentrates (magnetite and 35% wt of hematite).
The system (12) predicts in real-time the process and product parameters, that cannot be measured directly, thus, providing real-time optimization of the furnace operation, and thereby reducing the operating and production costs.
Iron ore fines are agglomerated into pellets and then indurated using a furnace to create iron ore Green pellets are then transported to the induration process. » Learn More induration of iron ores
In this work, a mathematical model of the pilot scale iron ore pellet induration furnace is presented. The validity of the model has been verified by performing separate experiments of subprocesses: drying, firing and cooling.

In the present pelletizing apparatus, the induration of iron ore concentrate pellets is achieved in a tunnel furnace heated by plasma torches, wherein the generation of CO2 by the conventional iron ore pelletizing processes is reduced by using electricity powered plasma torches instead of burning natural gas, heavy oil or pulverized coal in burners, thereby reducing considerably industrial ...
Several investigations1-7 were carried out to study the induration of iron ore green pellets. However, most of such studies have been based on either with total induration process or modelling on the induration process.
Abstract Mathematical model for a pilot scale iron ore pellet induration furnace has been developed which considers the process of induration including the reactions of limestone, magnetite and coke.
