What are pellets?
Pellets are the ground iron ore fines converted to spherical shape balls having good physical properties for
both bulk, mechanical transportation over long distances and also have excellent metallurgical properties
similar or even better than lump ore.The pellets become a vital raw material for all types of Iron Making
Units.They are made with technology that uses the powder that is generated during the ore extraction
process, once considered waste.
What are they used for?
Affordable, high-quality raw materials for iron making are steadily decreasing on a global scale. This means
that fine and ultra-fine iron ores will command an ever-larger share of iron ore sales in the future. For this
reason, a growing number of iron and steel producers are looking into the possibility of increasing the
portion of pellets in their production operations. The use of pellets, however, leads to a number of issues.
Fluctuating prices on the world market can seriously affect cost-efficient ironmaking.
The pellets are used as raw material for Iron making in the plants as an alternate material for Sinter and/or
Lump Ore.
The pellets are preferred over sinter and lump ore as their shape, size, strength and excellent designed
metallurgical properties in Blast furnaces as burden. The use of pellets resulted in increasing the
productivity of the iron making units without any capital investment. The designer pellets with known
chemistry facilitate reduction in coke rate and the slag chemistry over the conventional burden.
