Abstract
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.
Claims5
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.
