A rotary kiln is a steel round shell with refractory lining that rotates. This shell is rotated by a drive gear and electric or hydraulic drive system. The shell is supported on large bearings. There is a single large burner that heats the pellets up as they travel through the kiln. Annular cooler. An annular cooler is a turntable that holds the hot pellets. Ambient air is blown through the hot pellets. The turntable is made of wedge shaped pans. The pellets fall out of the kiln directly ...

The production of iron ore pellets, which is vital to the production of steel, is expected to be an important industry for many years to come. The pelletizing of iron ore is often performed in the 'Grate-Kiln' process, in which the iron ore is heated, first on a traveling grate and then in a rotary kiln.

There are a number of processes for the production of sponge iron. In one of these processes green pellets are hardened on a traveling grate at low temperatures and then reduced to sponge iron in a rotary kiln. Besides pelletizing, there is the sintering method for bringing the particles of a fine ore into lumps.
