Abstract
Apparatus for mixing powdered or granulated substances, for example a substance containing ammonium nitrate, and a liquid substance, for example nitroglycerin, which apparatus comprises a mixing vessel, characterized in that the mixing vessel has a length exceeding the length of the mixing vessel considered in the longitudinal direction of the screw or screws, and in that the portions of the screw or screws extending out of the container are enclosed in an outlet tube connected to the container, and because each outlet tube with the enclosed screw is made of a manner such that the forced mixed substance outside the screw is forced to move back in the longitudinal direction thereof, in order to achieve the mixing.
