MAIN BENEFITSTHE CUSTOMER• Intensive mixing and granulation system for
optimized raw material preparation

Name: National Mineral Development Corporation
Location: Nagarnar, India• Utilization of hot off air from the cooler ascombustion air for the ignition furnace

NMDC is India’s largest iron ore producer andexporter. The state-owned company currently
mines more than 25 million tons of iron ore per
year at a number of sites throughout the country.
The new steel plant will be built in the vicinity ofthe Bailadila iron ore deposit.

THE CHALLENGE

THE SOLUTIONSCOPE OF SUPPLYNational Mineral Development Corporation Limited(NMDC), an Indian government-owned mining company
headquartered in Hyderabad, placed an order with aconsortium headed by Primetals Technologies for thesupply of a sinter plant on a full turn-key basis. This plant
will be part of a new steelworks that NMDC plans to build
in Nagarnar in the Indian state of Chhattisgarh. As partof a national campaign to increase the steel output inIndia, NMDC will build a 3 million t/a integrated iron- andsteelworks at Nagarnar.

The sinter strand will have a suction area of 460 m2 and will

The Primetals Technologies scope of supply for this project
includes basic and detail engineering for the entire sinterplant; the complete equipment supply comprising raw
material preparation and material handling, the sintermachine, sinter cooler and offgas treatment facilities; theelectrical, media supply and automation systems; andspare parts. Advisory services for erection, installation,start-up and commissioning will be provided, in addition topersonnel training.

be capable of producing 4.75 million tons of high-quality
sinter per year. A highlight of this project includes theinstallation of the Intensive Mixing and Granulation System(IMGS) from Primetals Technologies for the preparation of
the sinter raw mix. This solution will enable a thoroughly
homogeneous sinter raw mix to be achieved, which is animportant factor for the production of high-quality sinter as
required by the blast furnace. Furthermore, a much higher
portion of lower-cost, ultra-fine iron ores can be used in
the sinter mix, thus decreasing the specific costs for theproduction of sinter. The sinter plant and downstream
equipment and environmental facilities will be designed toallow for a future capacity increase.
