Direct-fired rotary kilns offer efficient processing for high temperature applications. A direct-fired rotary kiln heats material by passing the combustion gases through the rotary kiln. The combustion can either occur in a com-bustion chamber if direct flame radiation is to be avoided, or the flame can be directed down the length of the rotary ...

The essential design elements of a rotary kiln are shown in Fig 1 and Fig 2. The rotary kiln consists of a lined hollow cylinder, mounted in an inclined position on rolls and rotated slowly by a drive. The charge material moves from the feed end to the discharge end as a result of the rotary motion and gravity.

For these most common rotary kiln materials, high temperatures in the range of 1100°C / 2000°F are used to instigate a chemical conversion (cement and lime) or to fuse fines (fine ore powder) into pellet form (iron ore). Most rotary kilns are direct fired – with a flame shooting into the kiln from the discharge end (the fire wall).

The first step in sizing a rotary kiln entails thermal and chemical analyses that gather information on reaction temperatures, heat transfer properties, potential unintended reactions, and more. Depending on the process and the material, some of this data may be published. Upon completion of a thorough thermal and chemical analysis, additional ...
