Listing description
Iron ore pellets
are spheres of typically 6–16 mm (0.24–0.63 in) to be used as raw
material for blast furnaces. They
typically contain 67%-72% Fe and various additional material adjusting the
chemical composition and the metallurgic properties of the pellets.[1] Typically limestone, dolostone and olivine is added and Bentonite is used as binder.
Detailed description
The process of pelletizing combines mixing of the
raw material, forming the pellet and a thermal treatment baking the soft raw
pellet to hard spheres. The raw material is rolled into a ball, then fired in a
kiln to sinter the particles into a hard sphere.
The configuration of iron ore pellets as packed
spheres in the blast furnace allows air to flow between the pellets, decreasing
the resistance to the air that flows up through the layers of material during
the smelting. The configuration of iron ore powder in a blast furnace is more
tightly-packed and restricts the air flow. This is the reason that iron ore is
preferred in the form of pellets rather than in the form of finer particles.
