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 .

The rotary kiln was invented in 1873 by 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. Upper limits on diameter are set by the tendency of the shell to deform under its own weight to an oval ...
