    Direct Reduction Process Description

    After reduction, the solids are discharged into a sealed rotary cooler, where water is sprayed on the cooler shell to reduce the temperature of the solids to about 200 F in a non-oxidizing atmosphere. The cooled material is then separate into DRI, DRI fines, and non-magnetics by a series of screens and magnetic separators
