rotary kiln process of making sponge iron chapter

The chemical process involved in making sponge iron removes oxygen from iron ore by using a reducing agent in the form of noncoking coal [Patra et al, (2005)] The reduction process is carried out in an inclined horizontal rotary kiln, which rotates at a programmed speed A temperature profile ranging from ensp 0183 enspThe sponge iron is discharged to the cooler drum from the end of the rotary kiln The temperature inside the rotary kiln is in the range of 1000–1100 176C and the retention time inside is about 5–9 h After that the sponge iron at high temperature is discharged to the fixed screen and sent to the cooler drum to be cooledrotary kiln process of making sponge iron chapter 3
