Modification of Wet Granulation Process During Iron Ore

01/07/2020 Granulation plays a critical role in iron ore sintering process. It influences not only the green bed permeability before ignition, but also the high temperature reactions such as fuel combustion, primary sinter melt formation during sintering. Granulation is the process in which primary particles of fines enlarge their size by forming multiple groups called green granules. Whereas the raw

Influence of Coating Granulation Process on Iron Ore

It does not fully respond to the low grade iron ore associated with goethite and limonite. This has led to deterioration in sinter properties and productivity. In recent years the improvement in the quasi‐particle structure with the granulation process is an effective method for improving sinter quality and productivity. To improve the sinter quality and productivity for low grade iron ore
