  • Apparatus for reduction of the grain size of crystalline explosive
    Patent number: 5682004
    Abstract: A method and an apparatus for reducing the grain size of crystalline explosive provide for, first of all, dissolving the coarse crystalline explosive in an organic solvent. Subsequently, the dissolved explosive is brought together with ice water in a precipitation reactor. In the precipitation reactor the precipitation and crystallization of the explosive occur, while turbulent agitation takes place. A filtration stage is connected downstream of the precipitation reactor. A fine crystalline explosive is obtained, having a mean particle size of from 4 to 6 micrometers.
    Type: Grant
    Filed: December 3, 1996
    Date of Patent: October 28, 1997
    Assignee: Wasagchemie Sythen GmbH
    Inventors: Gregor Fels, Gerhard Ewald
