A rotary kiln is classified as a direct-fired or indirect-fired kiln depending on the heating method and can be selected considering which process is more suitablehe direct-fired has the advantage of high heat efficiency, but the generation of exhaust gas is large, and subsequent treatment is required more.Get Price
Fundamentally, rotary kilns are heat exchangers in which energy from a hot gas phase is extracted by the bed materialuring 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.Get Price
