Drying of Iron Ore Pellets - Analysis with CFD

Before iron ores enter the blast furnace, it is necessary to remove a great portion of the mineral ballast components by graining. To remove these contaminations, concentrates are very fine grained and agglomeration is therefore necessary. Agglomeration can be achieved by pelletizing and sintering. Ores containing large quantities of contaminations must be very fine-grained, and can therefore ...
