The working principle of rotary kiln:
The rotary kiln belongs to rotary cylinders, it is one of industrial furnaces and non-standard equipment. There is firebrick lining and heat exchange device in the cylinder,make the rotation as low velocity. Generally it will be counter-current flow heat transfer for the material and hot air,the raw material will be fed from high end of kiln(also known as cold end), discharge from low end.Heat up the energy (electricity/ gas），because of slanting installation of cylinder, the material in the kiln tumbles along the direction of circumference,at the same time,it moves along the axial direction. Flue gas will be discharged from high end. The material will be heated up in the process of moving, after sical and chemical change,the acceptable product after the calcination will be discharged from low end.
The rotary kiln is classified according to the material:
