The working principle and structure characteristics of rotary kiln

rotary kiln

Raw material is entered from high-end of kiln tail shell to the inner kiln shell for calcination. The inclination and slow rotation of kiln shell makes material roll along circumferential direction and along axial direction from high end to low end. Through decomposition, calcination, cooling and other technical process, the raw material is burnt to cement clinker and then discharged from the low end of kiln shell and entered cooler.

The fuel is puffed from kiln head, burnt inside the kiln, and the heat giving out is used to heat the raw material, to make the raw material calcine to clinker. The hot air formed during the process of material heating exchange is entered from kiln feeding end to kiln tail system, and then vent the gas by chimney.
