Cement rotary kiln working principle

The material is fed into the kiln through the kiln tail (high end) chute. Due to the inclination and slow rotation of the cylinder, the material rolls along the circumference while moving in the axial direction from the kiln tail (high end) to the kiln head (low end); The kiln head end (low end) is sprayed into the kiln through a burner for combustion, and the heat is transferred to the material by radiation and conduction.

After the material is calcined in the moving process, it is discharged from the kiln head end, and the high-temperature flue gas is discharged from the kiln head end. The tail end enters the kiln tail dust removal system.
