Rotary Kiln Dri Process

Rotary Kiln Dri Process

kiln process.1 In this process approximately 1.5 tons of lump ore -31.53.15mm 800 kg of coal and 40 kg of dolomite are fed to a kiln to produce 1 ton of DRI. At the kiln exit the transfer of material is through a transfer chute closed off from the atmosphere through which the material falls into a rotary cooler. The DRI produced in the .

    Direct Reduced Iron DRI also known as Sponge Iron offers an alternative steel production route to BF-BOF and Scrap-EAF routes. In DRI iron ore is reduced in its solid state – unlike BF process where a liquid metal is formed during reduction. DRI can then be transformed to steel in electric arc furnaces. DRI production is common in Middle East South America India and Mexico.
