High Efficiency Rotary Kiln Furnace Cement Rotary Kiln Power 37 kw
Introduction of Cement Rotary Kiln
Cement Rotary kiln is a pyroprocessing device used to raise materials to a high temperature (calcination) in a continuous process.
Materials produced using cement rotary kilns include:
Cement, Lime, Refractories, Metakaolin, Titanium dioxide, Alumina, Vermiculite, Iron ore pellets, etc.
They are also used for roasting a wide variety of sulfide ores prior to metal extraction.
Main Components of Cement Rotary Kiln
the shell
the refractory lining
support tyres and rollers
drive gear
internal heat exchangers
The fuel for this may be gas, oil or pulverized coal.
Working Principle of Cement Rotary Kiln
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 large bunsen burner.
