Iron Ore Processing | Home

These iron ore pellets are transported from Sweden to Norway for shipping. In 1902, a train line was built all the way to Narvik for this purpose. At the time this was the most northern train line in the world. The trains using this route pull up to 68 rail carts and transport around 33 million tons of iron ore per year.

Heat Transfer in a Bed of Dry Iron Ore Pellets

The bulk thermal conductivity of a bed of pellets, k, can be estimated from Eq.(2) and literature values of the heat capacity of iron ore. Literature values of iron ore at room temperature fall between c = 550 and 560 J kg –1 K –1, 1,8) while the bulk packing density of the pellets used in this experiments was determined to be approximately ρ = 2000 kg m –3.

Iron ore green pellets show both plastic and elastic behaviour and the difference in significance between these two mechanisms should be recognised. Plastic deformation occurs due to the load of above-lying green pellets in a static bed of green pellets and leads to decreased bed permeability in the drying zones.
