The coal base DRI rotary kiln process for production of DRI / Sponge Iron has its many parameters to increase the quality as well as productivity which need careful operations through out the process. Number of DRI processes came up and rotary kiln process with solid coal as fuel found to be most acceptable process in the world.
Iron Ore and Coal are drawn with the help of weigh feeders in the required quantity and proportion and fed on to common conveyor. These raw materials enter into the rotary kiln through a feed chute. 4. The rotary kiln is 70 meters in length and 4.4 meter in diameter. This kiln …
However, Rotary kiln process suffers from serious limitations like low productivity and pollution. In this respect fixed bed Tunnel kiln furnace are evolving as an alternative to Rotary kiln process. Iron ore fines and the low grade beneficiated iron ore cake are directly used for manufacturing of sponge iron in tunnel kilns.

This study focuses on sponge iron kiln based process. The chemical process involved in making sponge iron removes oxygen from iron ore by using a reducing agent in the form of non-coking coal [Patra et al, (2005)]. The reduction process is carried out in an inclined horizontal rotary kiln, which rotates at a programmed speed.
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.
