ResonantAcoustic® Mixing Principles


ResonantAcoustic® Mixing Principles

ResonantAcoustic® Mixing (RAM) is a non-contact mixing technology that relies upon the application of a low-frequency acoustic field to facilitate mixing. This emerging technology has demonstrated mixing performance advantages for many complex and multiphase systems. RAM technology is well suited to meet the most demanding mixing processes including advanced polymer applications and is currently being used in the polymer processing industry. The RAM technology approach for acoustic mixing works on the principle of creating micro-mixing zones throughout the entire mixing vessel. This approach differs from conventional mixing technology where mixing is localized at the tips of the impeller blades, at discrete locations along the baffles, or by commingling products induced by tumbling materials. RAM technology provides faster, more uniform mixing throughout a vessel than can be created by conventional systems. RAM technology has the added advantage that it does not use impellers, or other intrusive devices to mix, nor does it require unique vessel designs for a broad range of mixing applications.

RAM technology is designed to operate at mechanical resonance. This operating condition results in the transfer of the mixer system's mechanical energy into the materials being mixed. This condition is achieved by matching the mechanical operation of the mixer with the properties and characteristics of the range of materials to be mixed. The operating characteristics of the mixer are automatically sensed and controlled with "smart mixing" technology in order to keep the mixing system operating at peak performance. To learn more, please join us for a presentation on the principles of ResonantAcoustic® Mixing and view a live demonstration. A LabRAM (bench top) Acoustic mixer will be used for the on-site demonstration.


Speaker Background

Mr. Josh Yarrington is a Sales Engineer at Resodyn Acoustic Mixers, Inc. He has a BS in Mechanical Engineering from Northern Arizona University. He began with Resodyn Corporation in 2005 as a mechanical engineer, and has been a sales engineer with Resodyn Acoustic Mixers since 2007. He was involved with ResonantAcoustics® Mixing (RAM) initially as a design engineer and in the manufacturing of the RAM technology. He works directly with clients and RAM users. He has gained an extensive knowledge of applications using ResonantAcoustics® Mixing from both internal studies and interaction with the growing number of RAM users over the past four years. He assists with client process development and continued research where RAM processing technology may be applied.
