  • Continuous method and apparatus for the preparation of explosives emulsion precursor
    Patent number: 4472215
    Abstract: 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.

  • Water-in-oil emulsion blasting agents containing unrefined or partly refined petroleum product as fuel component
    Patent number: 4404050
    Abstract: A water-in-oil emulsion explosive composition is provided wherein the continuous carbonaceous oil or fuel phase comprises an unrefined or partly refined petroleum product, for example, slackwax. The resulting explosive composition exhibits properties of strength, detonation velocity and stability comparable and in some cases superior to similar compositions containing refined petroleum fuels.
