Cement Rotary Kiln

ACementRotary kilnis apyroprocessingdevice used to raise materials to a high temperature (calcination) in a continuous process.

Materialsproduced using cement rotary kilns include:

Cement,Lime,Refractories,Metakaolin,Titanium dioxide,Alumina,Vermiculite,Iron ore pellets etc.

They are also used forroastinga wide variety ofsulfideoresprior to metal extraction.

Main Components of Cement Rotary Kiln

1. the shell
2. therefractorylining
3. support tyres and rollers
4. drive gear
5. internal heat exchangers

Thefuelfor this may be gas, oil or pulverized coal.

Cement Roatry Kiln Principle of Operation

The cement rotary kiln is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly about its axis.

1.The material to be processed is fed into the upper end of the cylinder. As the kiln rotates, material gradually moves down towards the lower end, and may undergo a certain amount of stirring and mixing.

2.Hot gases pass along the kiln, sometimes in the same direction as the process material (co-current), but usually in the opposite direction (counter-current). The hot gases may be generated in an external furnace, or may be generated by a flame inside the kiln. Such a flame is projected from a burner-pipe (or "firing pipe") which acts like a largebunsen burner.
