Aluminized Explosive Processing Using Twin Screw Mixer/Extruder Technology

There is a need within the US Navy to develop and demonstrate an alternative manufacturing technique to manufacture an aluminized, pressed explosive for specialized operations.  A manufacturing technique has been demonstrated using twin screw mixer/extruder technology that produces an aluminized explosive that exhibits enhanced performance with equal or better sensitivity characteristics.  The remote manufacturing process was developed using a 40mm twin screw mixer/extruder integrated within inline granulator.  This manufacturing process is a more safe process that yields product of equal or better quality at a reduced manufacturing cost.

Information shall be presented on the developmental approach, equipment design and installation, manufacturing effort as well as laboratory analysis of the pressed explosive that was manufactured using the 40mm twin screw extruder facility. 

The Naval Surface Warfare Center, Indian Head Division has successfully developed a manufacturing method for a pressed, aluminized explosive that has good performance and sensitivity characteristics along with reduced environmental impact.
