    Fundamentally, rotary kilns are heat exchangers in which energy from a hot gas phase is extracted by the bed material. During its passage along the kiln, the bed material will undergo various heat exchange processes, a typical sequence for long kilns being drying, heating, and chemical reactions that cover a broad range of temperatures.
