Feo Determination In Iron Ores

At 800 deg c the feo of the magnetite iron ore gets converted into fe2o3 in an exothermic reaction the liberated heat hardens the green balls which is helpful to withstand the tumbling impact due to the rotation of the rotary kiln a circular cooler is used for cooling of the fired pellets flowsheet of grate kiln process is given at fig 3.
