A process and apparatus is provided for the continuous manufacture of a water-in-oil explosive emulsion precursor. Separate streams of the water phase component and the oil phase component are introduced into an in-line motionless mixer. A chosen portion of the output from the mixer is recirculated and returned to the motionless mixer for further emulsification. The process allows for the production of a very high phase ratio water-to-oil emulsion (up to 95% water phase) without phase inversion after long storage. The precursor is simply converted to a sensitive explosive by means of known density lowering techniques.

Continuous method and apparatus for the preparation of explosives

A process is provided for the continuous separation of suspended basic alkali metal azide particles from a liquid reaction medium by bringing the liquid reaction medium into contact with a non-reactive mineral oil whereby the suspended metal azide particles migrate into the mineral oil phase and are thereafter separated therefrom.
