e.Because of a poorer sealing,the rotary kiln is leaked into more air than vertical kiln,thus having lower concentrations of carbon dioxide while concentrations of carbon dioxide of vertical kiln are up to 30%. According to the domestic operating experience of similar type kiln, the carbon dioxide concentrations are generally not more than 15%.

Rotary kilnstarted to be used for lime manufacture at the start of the 20th century and now account for a large proportion of new installations if energy costs are less important.. The early use of simplerotary kilnshadthe advantagesthat a much wider range of limestone size could be used, from fines upwards, and undesirable elements such as sulfur can be removed.

Rotary kilns(sometimes called calciners orrotaryfurnaces) 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.Arotary kilnconsists of a cylindrical, rotating body mounted between stationary material feed and outlet housings.
