ABSTRACT:
A method for producing an emulsion explosive comprises introducing a liquid organic fuel phase and an immiscible liquid oxidizer phase into apparatus having a mixer chamber, flow constrictor means for introducing the liquid oxidizer phase as an emergent turbulent jet into the chamber to cause its fragmentation into droplets in situ within the chamber, means for introducing the fuel phase into the chamber so that the fuel phase introduced thereby contacts and becomes distributed around the droplets of oxidizer phase as they form to produce emulsion and further providing shear mixing means within the mixing chamber to effect enhancement of the mixing of the chamber contents and thereby to continuously incorporate the fuel phase to produce a more refined emulsion suitable for use as the basis for an explosive system, particularly emulsions of high velocity.
