Prediction of the granule size distribution of iron ore

In granulation for iron ore sinter production where a layer of fines is formed around large particles, the particle growth becomes a vital parameter to assess the effectiveness of the process , . In this study, the overall particle growth was defined by comparing the particle size before granulation with the granule size after granulation.

The smaller sized iron ore fines (lt;100 mesh) shall reduce the permeability of sinter bed and this in turn will generate more sinter return fines and thus productivity of sinter machine is affected. So the ideal size distribution of iron ore fines must be 10 to 0.15 mm and mean size of the ore fines shall be 3 to 5 mm.
