Abstract: The grate-kiln system for iron ore pellet induration is a nonlinear, high coupling and large delay process Considering the deviation between assumption and actual results, it is hard to build accurate kinetic models Besides, the pure kinetic model also has the limitations to describe the induration process
Iron was one of the most basic requirements of the rapidly industrializing British economy, and the country certainly had plenty of the raw materialsHowever, in 1700 the iron industry was not efficient and most iron was imported into Britain; by 1800, after technical developments, the iron industry was a ,
pre-requisite to ensure supply of quality iron ore to the steel industry This requires intensive crushing of iron ore to reach its liberation size
Introduction The process of iron ore pellet induration requires large , The current project was developed in a pelletizing plant that uses discs for pellets production , Basically the system is composed of the following equipment: 1
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 .
