Beschreibung
Zusammenfassung:	FIELD: explosive works. ^ SUBSTANCE: feeder contains bunker and horizontal gas pipeline and transport pipeline established in it with backlash, coaxial against each other. The vertical gas pipeline and branch pipe for powder supply in the bunker are in addition established in the bunker. Horizontal and vertical gas pipelines and the transport pipeline are established in the top part of the bunker above a cut of the branch pipe also located in the top part of the bunker. Besides, the feeder is supplied by the operated valves allowing serially directing a stream of nitrogen from the main pipeline in this or that gas pipeline, thus action of valves is synchronised with the installation actigram. It is possible to use one valve-distributor instead of two valves. ^ EFFECT: operating ratio of powder raises and stability and reliability of work of installation of detonation spraying during long term of operation is provided. ^ 3 cl, 3 dwg
