Modelling and optimization of a rotary kiln direct ...

2014-8-5  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
