| Abstract: | The present work identifies the basic features of burden movement in a rotary kiln. The cold model study was conducted with
iron ore as the feed material to determine the influence of length to diameter ratio (L/D) of a rotary kiln on the filling degree, hold-up, and residence time of the charge. An empirical equation correlating different
operating variables has been derived on the basis of the experimental results. The influence of individual parameters under
different conditions on the residence time and back spillage has also been evaluated.
