Iron ore is one of the two essential inputs for producing direct reduced iron (DRI); the other being natural gas or another hydrocarbon fuel that can be reformed to create a reducing gas rich in CO and H2. Although direct reduction processes can operate with pellets having an iron content of 65% or lower, typical of blast furnace (BF)-grade ...

In addition, a conditioning step can also be incorporated upstream of the pelletizing process, e.g. in the case of pelletizing iron ore, where the fine ore is initially mixed with bentonite. Eirich mixers with a usable capacity of 12 m³ have proved themselves for this purpose.
