The invention is a method and apparatus for formulating and delivering emulsion slurry blasting agents in a self-contained, “on-site,”movable system, such as a heavy duty truck which houses the necessary apparatus for formulating the emulsion blasting agent. A key part of the apparatus is a blender in which the emulsion phase is formed.

A method for the manufacture and bulk delivery of water-in-oil emulsion blasting agents comprising: (a) forming an oxidizer salt solution at a temperature above the salt crystallization temperature, (b) combining the salt solution with a liquid organic fuel and an emulsifier to form a fluid mixture

A method for the manufacture and bulk delivery of water-in-oil emulsion blasting agents comprising: (a) forming an oxidizer salt solution at a temperature above the salt crystallization temperature, (b) combining the salt solution with a liquid organic fuel and an emulsifier to form a fluid mixture thereof, (c) blending the fluid mixture to form a water-in-oil emulsion blasting agent in a blender comprising: (1) a housing having an inlet and an outlet, (2) a shaft rotably mounted within the housing, (3) a plurality of blades affixed to and extending in a lateral direction from the shaft and spaced apart along the axis of the shaft, (4) a plurality of stators rigidly mounted within the housing and interposed between some or all of the spaces between the blades, and (5) means for rotating the shaft and blades, and the step of rotating the shaft and blades to shear the fluid mixture and thereby form an emulsion phase. (d) delivering the resultant emulsion blasting agent directly into a borehole or other receptacle.
