Tunnel Kiln Of Dri Nov - Evert Bioenergie

In the Direct Reduced Iron (DRI) plant, production of sponge iron using a solid reductant involves reducing iron ore (lumps/pellets) with a carbonaceous material such as coal. The reduction is carried out in a rotary kiln (which is inclined and rotates at a pre-determined range of speeds) at a stipulated temperature (850°C -1,500°C).

Direct Reduced Iron (DRI) Production Plant

Sponge iron being magnetic gets attracted and gets separated from non- magnetic char. The iron ore and coal crushed and screened to respective sizes are fed to rotary kiln through feed tube in pre-determined ratio. The rotary kiln is slightly inclined at an angle 2.5 deg and rotated by
