Coal based Direct Reduction Rotary Kiln Process – IspatGuru

Rotary kiln – It is the heart of the coal based reduction process since the reduction reaction takes place in this reactor. The diameter and the length of the kiln depend on its capacity. The kiln is generally lined with high alumina castable refractories throughout its length with dams at feed end and discharge end.
