Iron ore-coal composite pellets were made for the rotary kiln reduction purpose. Mixtures of raw iron ore, coal, NaCl (used as additive) and bentonite (used as a binder) were pelletized into a size of 5-8 mm composite pellets. A rotary kiln (Φ1.5 m × 15 m) was built for the reduction process, as shown in Fig. 4. Composite pellets were fed ...
The production of iron ore pellets is often performed in the so-called Grate-Kiln process. The aim of the process is to oxidize the magnetite (Fe3O4) to hematite (Fe2O3) and to sinter the pellets so they can be used in steel manufacturing. The heat required for this is produced by combusting a pulverized fuel in a rotary kiln, forming a suspension flame.
Sponge iron being magnetic gets attracted and gets separated from non- magnetic char. The iron ore and coal crushed and screened to respective sizes are fed to rotary kiln through feed tube in pre-determined ratio. The rotary kiln is slightly inclined at an angle 2.5 deg and rotated by
Rotary kilns are used for any number of purposes, from heating soil to remove volatile contaminants, to heating stones to remove moisture.
