Physical and chemical processes in shaft furnaces proceeds in counter – current system. Reacting gas carrying powders flows up in packed bed of descending metallurgical materials. In this system the problem of bed particles hanging up appears. That is why the author undertook the investigations of gas – powder flow in descending bed. Physical model with glass bed and glass powders was constructed. The experiments were carried out and the influences of gas velocity, type and size of powders, type and size of bed particles and powder concentration in gas were established. The conditions, in which bed hanging up appears were defined. Mathematical model of two phase gas + powder flow in moving bed was developed.
