Rotary Kiln Slope Calculation
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

Rotary Kiln
Rotary kiln incinerators usually have a length to diameter L/D ratio between 2 and 8. Rotational speeds range between 0.5 and 2.5 cm/s, depending on the kiln periphery. High L/D ratios and slower rotational speeds are used for wastes requiring longer residence times. The kilns range from 2 to 5 meters in diameter and 8 to 40 meters in length.
