Application
Rotary kiln is a pyroprocessing device used to raise materials to a high temperature (calcination) in a continuous process. Materials produced using rotary kilns include:Cement, Lime, Refractories,Metakaolin, Titanium dioxide, Alumina, Vermiculite, Iron ore pellets
They are also used for roasting a wide variety of sulfide ores prior to metal extraction
Working principle
The kiln is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly about its axis. The material will be calcined in the shell after feeding at the head of the kiln. The fuel will be spurted from the kiln tail and start burning. The hot air from the end blow into the kiln directly impacting the raw materials. And then will be turned over along the direction of circle and mixing from the high-end to low-end along the axial because of the shell’s slope and low speed rotation. The material will be calcined into the clinker after discomposition, calcination and cooling process. So they will discharge from the low-end.
