Sinter Feed Fine Fraction

The Measurement of Void Fraction in Beds of Granulated ...

Iron ore sinter feeds are granulated with water to improve permeability of the bed during sintering. The permeability of a packed bed is a complex function of the effective mean diameter of the granules and the void fraction of the bed.

Granulation behaviour of specularite fines in ferrous ...

The granulation behaviour of specularite fines which possess poor ballability was studied with limonite fines as a function of nuclei particles and adhering fines. The results show that the permeability of granules deteriorated as the ratio of specularite fines increased in the mixture, and the optimal granulation moisture content also decreased.
