FIELD: pneumatic transportation facilities. SUBSTANCE: invention relates to pneumatic transportation of hot and cold loose materials, such as alumina or cement. Said chamber feeder has discharge nozzle on sleeve of which caps fitted which are provided with spaces from side of mating surfaces. Caps are installed without clearance for displacement along sleeve to form air supply channels. Lock is made in form of stopper fitted on sleeve. Air distributing holes of sleeve are tangential. Nozzle with self-closing air supply channels precludes getting of material particles into air distributing space, at charging of feeder and in case of plunging of transportation pipeline. Tangential holes of sleeve contribute to higher concentration of material and air mixture. EFFECT: improved transportation of loose materials. 2 cl, 4 dwg
