Design features of rotary cement kilns. The shell of the kiln is made of mild steel plate. Mild steel is the only viable material for the purpose, but presents the problem that the maximum temperature of the feed inside the kiln is over 1400C, while the gas temperatures reach 1900C.

Rotary kilns are a vital part of industrial processing, helping to carry out a wide range of chemical reactions and physical changes in hundreds of materials. The process of sizing a rotary kiln to meet the specific requirements of a given application is incredibly complex, and must take several factors and analyses into consideration.

The rotary kiln reactor utilizes traditional rotary kiln design. The moisture content of the feed materials must be controlled at 1015 by weight. The rotation speed is the key design parameter for the control of the product quality. If the speed is too slow, the reactor becomes the carbonization reactor and not the torrefaction reactor.

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

The rotary kiln provides constant mixing of the pellets, bringing all the pellets to the same temperature. In a straight grate, the pellets at the top of the bed are over cooked and those at the bottom are under cooked. Higher quality means fewer fines, better reducibility and less variation in compression strength.
