The Sintering Process of Iron Ore Fines – IspatGuru

Prior to sintering, there is an important process called granulation. Granulation is the homogenization of the iron ore mixture in a rotating drum with 7 % to 8 % of water with the objective of obtaining of a pre-agglomerated product, which is then delivered as a layer over a continuously moving grate or strand for getting the sintered product.

Granulation - an overview | ScienceDirect Topics

L. Lu, O. Ishiyama, in Iron Ore, 2015. 14.2.1.3 Chemical characteristics of iron ore. Granulation is generally considered to be a physical process involving the physical interactions of particles mainly through capillary forces. The influence of ore chemical characteristics on granulation is therefore largely neglected in the literature.

In the sintering process, iron ore fines are first granulated with addition of water to make ideal quasi-particles for securing the permeability of the sintering bed. Water, as a binder, is needed for effective granulation, however excess water does not favor the energy consumption as additional energy is required to drive it off during sintering.
