ABSTRACT Blaine fineness is one of the most important parameters in pelletising. While the lower Blaine fineness does not provide sufficient strength to the both green pellet and indurated pellet, excessively high Blaine fineness causes problem in pellet making. Optimum Blaine fineness of iron ore in the range of 1700–2250 cm2/g is usually used …

Jan 10, 2014· Volumetric expansion of iron ore pellets takes place during their reduction from hematite to magnetite and wüstite. It can be mainly attributed to the increased volume requirements for the anisotropic growth of magnetite (111) planes parallel to the hematite (0001) planes ( Frazer et al., 1975 ).

Aug 18, 2020· However, it is twice as difficult to get good quality pellets with low-grade iron ore fines. The Blaine fineness of the available iron ore decides various factors such as heat consumption, strength of the pellet's structure, and porosity of the structure. The pellet's strength at higher temperature gives burden stability.
