ABSTRACT:
In the case of an apparatus for dewatering and plastifying water-wet mixts of materials for manufacturing explosives, as for example mixtures for producing propellent charges, using a screw extruder with one or more screws having kneading and conveying elements and a housing, possibly made up of axial sections, with a filling port for the said mixture as wetted with water, certain steps are taken for stopping the formation of slurries at the back end or part of the screw extruder, that is to say at the filling port there is an outwardly widening drain port with a drain duct joined thereto in which there is a conveyor for clearing the expressed water and the solids therein and moving them to the back end of the screw extruder.
