Effect of Blaine Fineness on the Quality of Hematite Iron …

The results showed improved properties of iron ore pellets at an optimum Blaine number (2150 cm(2)/g) but, reduction degradation index was found to be very poor for the given ore. Further investigation showed that when MgO containing flux viz. pyroxenite was added, the reduction degradation index and swelling index of the pellets were improved for identical Blaine number and other optimized ...

Measurement of surface areas by permeametry

The relative fineness of an iron ore pelletizing feed may be derived from its specific surface. However, the Blaine Number calculated from air permeability data according to ASTM specifications relies on the presumption that the particles referred to in the derivation of the basic Kozeny-Carman equation are synonymous with the solid fragments composing the powder.
