Abstract:
A method for removing and reprocessing mixed explosive substances, removed from ammunition, wherein the method comprises:heating an inert heat carrier to a melting point of a fusible component included in a formulation of an explosive substance to be removed, and supplying the inert heat carrier under pressure into an ammunition casing onto a surface of the explosive substance, wherein said heat carrier has a density which is less than the density of each component of the explosive substance,filling a separator with the inert heat carrier, the separator being provided with first, second, third and fourth connections mounted from the top downwards in respect to the height of the separator to a level of the first connection, and determining the weight of said heat carrier,continuously supplying a mixture of the removed explosive substance and the inert heat carrier into the separator through the third connection in a turbulent flow in which the removed explosive substance is in a suspended state, wherein an upper layer of the inert heat carrier in a volume equal to a volume of the supplied mixture is continuously drained from the separator through the first connection,subjecting the mixture in the separator to stabilization, precipitation and continuous weighment,setting an upper limit to a weight of the mixture of the explosive substance and the inert heat carrier in the separator, and when said limit is reached interrupting the supply of the inert heat carrier into the ammunition casing and accordingly said mixture into the separator,holding a content of the separator for at least 10 minutes, wherewith the inert heat carrier is separated from the explosive substance,adding to the separator melted trotyl through the third connection, simultaneously discharging an amount of inert heat carrier equal a volume of the trotyl from the separator through the first connection, and then discharging separated and clarified inert heat carrier through the second connection to form a mixture of explosive substance and trotyl,mixing the mixture of explosive substance and trotyl to obtain a homogeneous mass, anddischarging from the separator through the fourth connection the homogeneous mass into an additional vessel for subsequent reprocessing.
