Pellets are balls produced from natural iron ores fines or concentrates of different mineralogical and chemical composition with remarkable properties such as:
Uniform size distribution within a range of 9mm to 15 mm diameter
High and even porosity of 25-30%
High iron (Fe) content of more than 63%
Practically no loss on ignition or volatiles
Uniform mineralogical composition in the form of an easily reducible hematite or hematite-bearing compounds
High and uniform mechanical strength
Low tendency to abrasion and good behavior during transportation
Sufficient mechanical strength even at thermal stress under reducing atmosphere
Following points are other important aspects of a pellet plant in context of Indian market:
Iron ore fines are available in abundance.
In few years Indian Pellet market will grow to 100 million ton per annum.
Iron ore pellet has an excellent export potential.
Prepared raw material results in lower cost of production in Blast Furnace and DRI.
Strong business sense considering price difference in fines and calibrated lump ore.
Reduces pollution at mines and iron making units.
Conserve non-renewable natural mineral resources.
Raw Materials
The proposed pellet plant will require Iron Ore fines, Additives (Limestone & Dolomite), Binders (Bentonite & Organic binders) and solid fuels viz; coal or coke breeze. Quantity and sources of the annual requirement of raw materials for 1.2 million TPA pellet plant are as given
Pellet Plant Facilities
There will be common facilities for all the three units like:
