METHOD FOR UNCHARGING OF AMMUNITION FILLED WITH HEXOGEN-CONTAINING EXPLOSIVES AND INSTALLATION FOR ITS REALIZATION Russian patent published in 2005 - IPC

FIELD: uncharging of ammunition filled with hexogen-containing explosives.

SUBSTANCE: the method is based on crushing of the explosive charge being in the ammunition body by action on the central part of the charge simultaneously by a face circular milling cutter and by jets of high-pressure liquid, the peripheral part of the charge is influenced by jets of high-pressure liquid by feeding them through the nozzle heads of the nozzle block being at the end of a hollow rod accomplishing a translational motion, the ammunition body accomplished a rotary motion, and extraction and transportation of the explosive mix and liquid are performed by feeding of low-pressure liquid jets through the nozzles of the nozzle block. The claimed method is realized with the aid of an installation, made in which on the face surface of the nozzle block installed at the end of the hollow rod, is a circular milling cutter with grooves located in the zone of action high-pressure liquid jets, and two nozzle heads are installed, their water-supplying ducts are symmetrical relative to the axis of the nozzle block. An additional nozzle head with water-supplying ducts is located on the side surface of the nozzle block.

EFFECT: enhanced safety of uncharging of ammunition and obtaining of explosive suitable for further use.
