  • Indirect-fired rotary kilns (furnaces) Strommashina

    The rotary kiln of indirect heating is a cylinder rotating on bearing rims mounted on the frame and covered by a fixed case where hot gases are pumped during the kiln operation. These gases heat up the outer surface of the rotary cylinder when touching it and provide transmission of heat to the processed material without any direct contact with it.

    IntroductionIndirect-Fired Rotary Kiln ApplicationIndirect-Fired Rotary Kiln AdvantagesIndirect-Fired Rotary Kiln vs Direct-Fired Rotary KilnIndirect-Fired Rotary Kiln Prospect on Disposal of WasteIndirect-fired rotary kiln has a combustion chamber on peripheral barrel. The heat generated by the combustion of flue gas is transferred to the material through the cylinder. The material is calcined at high temperature, and the calcined product is discharged from the discharge valve. The exhaust gas is treated or emptied or utilized. The indirect-fired rotary kiln is suitable for the production of various materials requiring indirect continuous heating.
