ResonantAcoustic® Mixing – Rapid Mixing of Viscous Polymer Resin


Resodyn Acoustic Mixers has developed a novel mixer product line that uses low-frequency, high-intensity sound energy for mixing. The mixer technology, trademarked as ResonantAcoustic® Mixing (RAM), is applicable to a broad range of mixing classes that include liquid-gas, liquid-liquid, liquid-solid and powder-powder systems. Highlighted in this bulletin is a comparison of the speed of mixing between RAM and traditional mixers.

Rapid Mixing of Highly Solids-Loaded Viscous Resin

A blend of nano- and micron-sized powders was mixed into a viscous polymer resin at solids loadings up to 80% by weight (approximately 100 million cP) for a client. The materials were mixed until uniform. The figure on the right shows a comparison between the client’s mixer and the ResonantAcoustic® mixer. For a material with a viscosity of 50 million cP the client’s mixer took eight times longer than the ResonantAcoustic® mixer and the 100 million cP material that the client could not mix was mixed in about an hour by the ResonantAcoustic® mixer.
