The main raw materials for the production of DRI by therotary kiln process are (i) sized graded iron ore or iron ore pellets, (ii) non-coking coal, and (iii) dolomite in small quantities to scavenge the sulphur. Iron ore of the right quality is the basic input for the coal based direct reduction process.
Sponge iron kiln’s cylinder: The design of the sponge iron rotary kiln cylinder is more reasonable. The cylinder is rolled with aQ235-B steel plateto ensure five mechanical properties, usually with automatic welding. The wall thickness of the cylinder is generally 25 mm, and that of the firing zone is 32 mm.

Iron ore and non-coking coalare the prime raw materials for the production of sponge iron. These are charged into a rotary kiln in requisite proportion along with some dolomite. Coal plays a dual role in the process by acting as a reductant as well as a fuel for providing heat to maintain the requisite temperature inside the kiln at 950-1050 o C. …
DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 °C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines.
