14-02-2017· 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.
14-02-2017· Volatile matter of the coal is to be optimum for coal based rotary kiln process. Coal with very low volatile matter result in very low reactivity of char, and thus give rise to poor metallized product. Very high volatile coals, though yield highly reactive char, are also not preferred since it increases gas volume in the kiln. Normally for rotary kiln process volatile matter is to be in the range of 25 % to 30 %.
