Mar 16, 2013· Major DRI production processes are either natural gas based or coal based. Feed material for the DR process is either sized iron ore of size ranging from 10 mm to 30 mm or iron ore pellets of size ranging from 8 mm to 20 mm produced in an iron ore pellet plant. The gas based process uses a shaft furnace for the reduction reaction.

In India, the standard DRI processes are modified in a minor way and thereafter referred to as customized/indigenous technology. Only trivial changes in terms of the feed ratio, length and the diameter of the kiln are made in the name of customized technology. These customized technologies are dominating the coal based sponge iron process in India.
