An equipment in the size of pilot-scale was used to collect experimental data for investigation of validity of the conventional steady-state model of material flow in rotary drums. Also, the transient data of the time required for material movement in the empty drum up to any specified cross section are also reported. The novelty of the work is that fine particles, in place of granular materials, were used in all of the experiments. The investigations reveals of the weak validity of the model for describing the bed depth of material at feeding zone as well as discharge zone. But, it is acceptable at mid zone.
