Patent ID: 7789983

Claim:
A method for making blast explosive molding powder, comprising: suspending energetic solids, which is other than an inorganic oxidizing agent, and a metal powder in a non-aqueous bulk phase fluid at a non-aqueous bulk phase fluid to explosive ratio by weight using a molding powder vessel so that the non-aqueous bulk phase fluid separates the energetic solids for forming an energetic solids and metal powder suspension for promoting a formation of properly sized molding powder granules during a distillation stripping of an organic solvent component where said suspending energetic solids and said metal powder is performed at a non-aqueous performance fluid to explosive ratio in a range of 4:1 to 7:1; adding lacquer to the energetic solids and metal powder suspension at a solvent of the lacquer to polymer ratio for achieving a mixture, said mixture comprising a lacquer, fluidized energetic solids and metal powder; optimizing of granulation for final granulation of the mixture at a non-aqueous bulk phase fluid to solvent ratio by weight in a range to form a fluidized metallized energetic molding powder; distilling the fluidized metallized energetic molding powder through a first distillation process to remove the organic solvent component of the lacquer; reclaiming the organic solvent component through the first distillation process; decanting the non-aqueous bulk phase fluid for recovering a wet metallized energetic molding powder; reclaiming the non-aqueous bulk phase fluid through a second distillation process for reuse of the non-aqueous bulk phase fluid; and drying the wet metallized energetic molding powder in an oven to form a dry metallized energetic molding powder, wherein said solvent of the lacquer to polymer ratio by weight is in a range of 14:1 to 18:1.
