sponge iron production in rotary kiln

OPERATIONAL ASPECTS OF SPONGE IRON PRODUCTION IN

Sponge iron process uses a rotary kiln for the reduction of high grade lump ores or pellets (Fig. 1). The feed is introduced together with reducing and de-sulphurizing agents (lime- stone or raw dolomite) into an inclined rotary kiln, heated counter current to the flow of hot gas and reduced to form sponge iron.
