DRI PLANT

In our Direct Reduced Iron (DRI) plant, production of sponge iron using a solid reductant involves reducing iron ore ( lumps/pellets) with a carbonaceous material like coal or lignite. The reduction is carried out in a rotary kiln ( inclined and rotating at predetermined range of speeds) at a stipulated temperature. The inclination and the rotary motion of the kiln ensure that raw material moves from feed end to discharge end of the kiln. During this movement the actual reduction of iron ore to iron takes place. The material discharged from the kiln is taken to a rotary cooler for cooling and the cooled product is separated from the coal char.
