“... [ResonantAcoustic® mixing] is a fantastic technology. It has revolutionized the way we mix for development of materials for additive manufacturing...”

- Nik Ninos,  Research and Development Manager, Calix Ceramic Solutions

“Resonant acoustic mixers from Resodyn have proven to be extremely valuable in graphene development for our clients. It is critical for nanotechnologies such as graphene to be processed with the level of exacting consistency and particle distribution, especially at low loadings, that RAM has proven to consistently achieve.”

- Research Scientist, European Nanomaterial Research Organization

“[We] mix different rheologies with powder metals, highly viscous, and the LabRAM II has proven it can do that effectively. We’re very impressed with the build quality of the mixer--it’s a nice, solid, well-thought-out piece of equipment. It’s done very well for us.”

- Managing Engineer, Major U.S. Research Laboratory

Dissimilar Powder Mixing

Dry ingredients can be difficult to thoroughly and consistently mix, particularly when the particles are of different sizes and characteristics. To illustrate effective and rapid mixing, 10 grams of fumed silica is blended with 100 grams of sand. Completed specimens exhibit no airborne fumed silica, demonstrating uniform blending at an order of magnitude difference in particle size.


Milling and Nano Coating

Coating larger particles with smaller ones is a common processing application, and milling is often a part of the same process. In this video, agglomerated carbon black particles are simultaneously milled to nano size particles that coat the plastic pellets completely in just a few seconds. The high speed video clearly illustrates the dispersion of carbon black particles, their de-agglomeration, and progressive and comprehensive coating of the plastic pellets.

Many polymer-based materials require the addition of dry or powder materials for specific performance characteristics or coloration. To illustrate dry powder incorporation in a viscous liquid, a small amount of dry ingredient is rapidly blended with a viscous liquid. The newly captured mixing phenomena reveal how the thoroughly blended and uniform mixture is achieved in a very short mixing time.
