Coal based Direct Reduction Rotary Kiln Process |

The process of direct reduction is carried out in a rotary kiln where the operating temperatures are maintained in a range from 1,000 deg C to 1,100 deg C. The product of the kiln (DRI and char mix) is then cooled in a rotary cooler with external water cooling system. The products of the kiln is screened and magnetically separated. DRI being magnetic gets attracted and gets separated from non-

Abstract: Direct reduction of iron ore with aid of either carbon or natural gas under controlled temperatures and pressures within a rotary kiln generates sponge iron as a product. However rotary kiln performance is adversely affected by the ring formation known as accretion. These accumulated sintered solid particles which gives formation of ring along the length of the kiln hinder material flow,
