It is an agglomerating process of converting iron ore fines into 'uniformed sized iron ore pellets' which can be charged directly into a blast furnace (BF) or into a vertical furnace or rotary kiln normally used for the production of direct reduced iron (DRI). The iron ore pellets are shown in Fig 1.
The structure of the iron ore pellets in the blast furnace allows air to flow between the pellets, which reduces the air resistance that passes up the charge layer during smelting. In addition, pellets provide advantages for end users, such as increased productivity of blast furnaces, increased opportunities for iron content in charging, and ...

When pellets were first introduced, a swelling tendency led to damage to the BF stack, poor permeability to gas flow, and irregular burden descent. The test does not apply to lump ore or sinter. An electrically heated furnace with a vertical reduction tube that contains a wire basket with room for 18 individual pellets is used.
