Mean residence time and holdup of solids in rotary kilns
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 n . Accordingly, MRT is proportional to and the size ratio L D , but inversely proportional to the rotation speed n and the kiln inclination .

Modelling and optimization of a rotary kiln direct
A calculation method was developed that allows for the prediction of the bed profile and residence time in a rotary kiln. The method is based on the principle of granular movement in a kiln as described by Saeman 1951 and Scott et al., 2008. It assumes the kiln is operating in the rolling regime, the active layer has zero thickness, and the bed is
