Abstract

Primary explosives, e.g. lead azide, dispersed in a liquid medium, e.g. enol, are filtered, washed and dried in a novel centrifuge, wherein the rotatable extractor basket has an open bottom, which is closed by peripheral attachment to the large open end of an invertible funnel. The small open end of the funnel is attached to an axial shaft, which can be raised and lowered, whereby said small open end can be held upright to retain the contents in said basket and lowered to invert the funnel to discharge the dried free-flowing explosive particles by gravity through said small open end.
