PROCESS FOR THE PRODUCTION OF INTERMEDIATE EMULSIONS FOR USE IN EMULSION EXPLOSIVES

摘要

A process for producing an intermediate emulsion comprising an oxidizer solution, fuel and emulsifter, which process comprises the steps of: (a) mixing in a micromixer an oxidizer solution with a fuel blend comprising a fuel and an emulsifier so as to solubilise a portion of the oxidizer solution in the fuel blend to produce a precursor product; (b) mixing the precursor product obtained in step (a) using a micromixer in one or more successive stages in order to form the intermediate emulsion.
