Aug 01, 2006· For rotary kilns without a discharge dam, an equation was fist given by Sullivan et al. (1927) to calculate the mean residence time of the solids: (1) MRT = 1.77 · L D · Θ n · β. Accordingly, MRT is proportional to Θ and the size ratio L / D , but inversely proportional to the rotation speed n and the kiln inclination β .

modern cement plant. The 2-base rotary kiln is a statically determined beam system, where the support load is always known. It is a shorter and wider kiln, with a reduced slope to maintain the material retention time, similar to a 3-base kiln. The larger diameter reduces the gas velocity and the dust recircula-tion, and secures a lower burning zone
