Reduction of iron ore briquettes into DRI in the tunnel ...

In the first and second generation tunnel kilns, iron ore & coal layers were separate. In the new design, iron ore lumps / briquettes and coal fines are mixed together and hence the reduction is faster. The loading &unloading systems are also simple. The third generation tunnel kilns are available in capacities from 30,000-70,000 tons per year ...
