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 .
