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 ...
