Resonant Acoustic Mixing Extrusion
Resonant acoustic mixing (RAM) technology was developed with the aid of a DOE grant from their Inventions and Innovation Program. Most conventional mixing requires impeller agitation. RAM induces microscale turbulence by propagating acoustic waves throughout the mix media. RAM devices are simple in design and can be made large enough to perform industrial scale processes. The use of RAM technology for EM formulation offers the ability to mix viscous high solids loaded formulations efficiently with minimal waste. SERDP and ESTCP have funded several projects to explore the utility of RAM for propellants, explosives and pyrotechnic formulations. In addition we are investigating mix in case and continuous processing as a means to further reduce hazardous waste.
