Abstract: The screw extrusion technology of composite explosives was reviewed from three aspects as below: security analysis of screw extrusion technology, the material type that could be processed by screw extrusion technology and the improvement of the material properties through improving screw extrusion technology. The problems that higher internal friction in single screw extrusion and lower pressure of twinscrew extrusion were indicated and the adaptability of conical twinscrew extruders was proposed.

Key words: explosive, single screw extruding process, twin-screw extruding process, multi-screw extruding process
