rotary kiln process of making sponge iron c

The present work identifies the basic features of burden movement in a rotary kiln. The cold model study was conducted with iron ore as the feed material to determine the influence of length to diameter ratio (L/D) of a rotary kiln on the filling degree, hold-up, and residence time of the charge. An empirical equation correlating different operating variables has been derived on the basis of

    There are tendency for formation of formation of clusters , agglomerates and accretion or ring formation during actual manufacture of sponge iron in the temperature range of 900 0 C to 1100 0 C. Ring formation is a phenomenon occurring exclusively in a rotary kiln, while clusters and agglomerates are common in both rotary kiln and shaft based processes

    Abstract. The formation of accretions or ’rings’ in rotary kilns used for the manufacture of directly reduced iron (sponge iron) affects the residence time of the charge, kiln hold-up, and the kiln output to a great extent. In this part of the work, the effect of ring formation was simulated at room temperature in a scaled-down model of a rotary kiln by inserting conical dams in the shape of frustrums of cones …

    MAGMA produces pig iron from iron ore, by the method of liquid-phase reduction of iron. In the process, iron ore fines & limestone are pre-heated by the off-gases of the smelting chamber in a rotary kiln, to temperatures of 900-1,000°C & then hot-charged into the MAGMA chamber. Coal is directly burnt in oxygen inside MAGMA

    Iron ore fines are usually subject to beneficiation and/or pelletisation thereby converting them back into hard rock-like shapes (pellets) with a proper tumbler index. These pellets are then used for making sponge iron. Rotary kilns have a drawback upon the size and quality of iron ore that can be used
