The disclosure relates to a method for producing composite explosives of the type hexotonal and octonal by the intermediary of a two-stage wet granulation process comprising a first granulation stage for producing primary granules of a certain amount of TNT (the primary TNT) suspended in water, together with other desired components in the explosive, with the exception of the aluminum powder, which, in its turn, is mixed into the remaining amount of secondary TNT in order thereafter, in a secondary granulation stage, to be added to the mixing water with the primary granules suspended therein, for a successive build-up of their surface layer.

Method for the manufacture of composite explosives

The disclosure primarily relates to a method of phlegmatizing crystalline or otherwise particulate explosive substances or compositions in which these are included, by first coating the discrete particles with a thin layer of oxazolin wax in order thereafter to carry out a conventional wet-granulation with a true phlegmatization agent or a binder agent, such as one of the wax types included under different explosive standards or a plastic composition. The invention also concerns products manufactured according to said method.
