The low grade iron ore deposit of Pur-Banera Belt of Rajasthan has remained unexploited even though it was explored by Geological Survey of India, way back in the year 1969-70. After assessing the potential of Pelletisation of iron ore in India, Jindal SAW Ltd. a leader in India's Tubular market, planned to set up a 1.2 MT Per Annum pellet plant integrated with beneficiation plant situated at mine pit head near village-Pur, District-Bhilwara in the State of Rajasthan.
Jindal SAW Ltd. with their innovative ideas and international exposures is upgrading iron ore (ROM) from about 30% Fe to concentrate of 65% Fe by way of magnetic separation and other separation methods as the Ore is mostly magnetite along with banded magnetite quartzite. The magnetite concentrate thus produced is being used for manufacturing of pellets. Iron ore pellets are commonly used in iron making processes like modern blast furnace process, COREX, sponge iron or DRI making etc. Pellet manufacturing belongs to 'Primary Metallurgical Process', which includes ore extraction, ore beneficiation, pelletization or sintering and metal extraction.
The foundation Stone of JSL's Pellet plant in Bhilwara was laid down by Honourable Chief Minister of Rajasthan, Shri Ashok Gahlot, on 11th September 2011. The construction work of pellet plant was started in April 2012 and plant got hot commissioned on 13th May 2013 in a record duration of 14 months. Finally the production of pellet was started smoothly on 30th May 2013.
This is the first Pellet Plant of North India based on a captive iron ore mines and only operating plant in India based on magnetite iron ore concentrate. The pellet plant is based on Grate-Kiln technology supplied by Sinosteel Equipment & Engineering Co. Limited, China. It is a modern pellet plant where comprehensive measures have been taken for protection as well as improvement of surrounding environment.
- Pelletization process based on Grate-Kiln technology.
- The Iron ore concentrate is mixed with Bentonite and other additives, thereafter it is fed to balling disc.
- In the balling disc, green balls of size 6-16mm are made.
- In the travelling grate, green balls are preheated and become strong enough to be transferred to rotary kiln.
- In rotary kiln, the pellets are indurated at 1250 to 1300°C
- The hot pellets are transferred to annular cooling chamber
- Finally, Pellets are stored in stock yard for dispatch
