Sintering studies of Iron Ore Fines of Hospet-Sandur ...

Sintering is a technology for agglomeration of iron ore fines into useful blast furnace burden material. In sintering, a shallow bed of fine particles is agglomerated by heat exchange and partial fusion of the mixed mass. Heat is generated by combustion of solid fuel and mixed with the bed of fines being agglomerated. The combustion is initiated by igniting the fuel exposed at the surface of ...
