Pellets

SEML is one of the first few companies in the country to produce Pellets from Iron ore Fines using Grate-Kiln technology. The technology facilitates production of superior grade feed material for DRI and Blast Furnace using ore Fines which are otherwise unusable.


After wet grinding the Fines, dewatering is done. The fine sized concentrate is mixed with binder and other additives, and green balls are formed in the Disc Pelletisers.



The green pellets are dried and preheated in travelling grate then indurated in Rotary kiln & then after cooling in Annular cooler, final product is conveyed to stockpile.



The majority of the Pellets produced is used in house for production of DRI. The capacity of the Pellet Plant is 0.9 million tons per annum.
