The Determination Of Optimum Granulation Moisture Of Iron

The determination of optimum granulation moisture of iron

The most common agglomeration process in iron and steelmaking is sintering. The process requires the use of iron oxide ores or concentrate mixtures, limestone and dolomite as fluxes and coke as fuel in order to produce the required melt at elevated temperatures to cause permanent bonding of particles. Prior to sintering, granulation of the mixed feed is required to effectively cause temporal ...

Intraparticle Water Migration Dynamics During Iron Ore

IntraParticle Water Migration Dynamics during Iron Ore

During iron ore granulation, water first infiltrates through ore particles under the influence of capillary force to reach the surface and then migrates further into ore particles. Therefore water transportation should be evaluated separately in two dynamical phases, namely inter-particle infiltration and intra-particle migration.
