Rotary Kiln Shell Design
The cylinder of the rotary kiln's main structure is the kiln shell, rim, and thrust roller. Shell is the main part of the rotary kiln. It is a steel plate with a 40mm thickness, which is near the rim. Because of the high load-bearing, the thickness near here is much thicker. There is a layer of 200mm refractory bricks on the inside of the kiln.

Direct Reduction Process
This is a straightforward calculation, requiring values for the iron content of the feed, metallization of the DRI, and DRI carbon content [115]. One example of these calculations can be seen in Figure 1.2.32. Here the desired ratio is plotted as a function of metallization and carbon content for a specific iron content (in this case, 67% ...

Because the reactor is inclined from both the feed end to the discharge end, its rotation causes the iron ore and coal to mix and travel downward towards the exit. The rotational speed of the reactor can be adjusted to maintain the desired loading of the kiln and provide the required time to complete the reduction of the iron ore.
