A Rotary kiln is a pyroprocessingdevice used to raise materials to a high temperature calcination in a continuous process.

Cement rotary kilns refer to cement rotary calcining kilns sometimes called rotary furnaces it is a pyroprocessing device used to heat materials to high temperatures in a continuous process the kiln body is a cylinder vessel with a certain degree of tilt to the horizontal level.

Understanding the difference between a kiln and a furnace is not so hard, once you know their true definitions. A kiln is usually charged filled with stuff, then heated to fuse the stuff, then cooled, and the stuff removed. A furnace is usually heated first, then charged, then the stuff removed, and the furnace eventually cooled though not always.

The rotary kiln was invented in 1873 by the Englishman Frederick Ransome.. Kiln shell. This is made from rolled mild steel plate, usually between 15 and 30 mm thick, welded to form a cylinder which may be up to 230 m in length and up to 6 m in diameter. This will be usually situated on an eastwest axis to prevent eddy currents..

The kiln used in wet type production, which produces slurry with water content of 32-40 from raw materials, is called the Wet Type Rotary Kiln. Due to the liquidity of the slurry, the raw materials are sufficiently mixed, making clinker of high quality, which is the main advantage of wet production.

The rotary kiln reactors that process the particulates com-monly use lifters or called flight along the length of the sys-tem to lift solids 4.

Rotary kilns sometimes called calciners or rotary furnaces are used for thermal treatment processes such as calcination, sintering, pyrolysis and firing, as well as for oxidation and reduction. These treatments can be applied to powders, granulates, suspensions and green bodies.
