Over the past few years, scholars have already done lots of researches on the rings growth behaviors in rotary kilns. Researchers 12,13 studied the mineral phase structure of the rings in the pellets rotary considered that the formation mechanism of the rings is dominantly attributed to the solid phase consolidation of the iron oxide and liquid phase agglomeration of low melting

Kiln body of rotary kiln is the main part of rotary kiln. Its general length is from 30 to 150 meters. It should be laminated refractory brick before running. Kiln tail looks a lot like a lid. It is in the feed end. It is also important which undertakes the ability to feed. Rotary kilns support frame makes kiln more firm.

The rotary kiln was invented in 1873 by Frederick Ransome. This is made from rolled mild steel plate, usually between 15 and 30 mm thick, welded to form a cylinder which may be up to 230 m in length and up to 6 m in diameter. Upper limits on diameter are set by the tendency of the shell to deform under its own weight to an oval cross section
