FIELD: mechanics.
SUBSTANCE: proposed proportioner comprises powder bin, powder-proportioning element, device to feed transported gas and discharge gas-powder mix. The latter represents a channel communicating with detonation unit barrel, while powder proportioning element represents inclined site that allows varying powder looseness cone and is furnished with chamber to discharge gas-powder mix. Aforesaid chamber features resistance to gas motion lower than that in the other channels. Additionally, proportioner incorporates replaceable jet fitted at the bin base ahead of powder proportioning element.
EFFECT: proportioning various powders, higher reliability, and simpler design.
