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. A rotary kiln consists of a cylindrical, rotating body mounted between stationary material feed and outlet housings.
