A New Nano-mixing Technology Based on Solid Oscillation Spectrum (SOS)

The industrial application of nanotechnologies is limited by the scalability of laboratory results. The scaling is either impossible or so expensive that it is almost impossible.

Mixing is the most important stage in many nanotechnologies: from pharmaceuticals and cosmetics to propellants. In many nano processes, traditional industrial mixers (such as agitators, extruders, blenders and others) produce mixtures that are too uneven, have long mixing periods and are hard to maintain. Moreover, in many cases these instruments are useless because of the mixing time tends to infinity.

Currently proposed alternatives are the linear vibration mechanical mixers of Resodyn Acoustic Mixers (RAM). RAMs blend various types of materials avoiding the problems of using impellers or blades. RAMs are much faster than traditional mixers and can mix materials where conventional mixers have failed. These results are possible due to the RAM driver that can create accelerations up to 100G.

However, the RAM driver requires a very complicated operation system. Three additional disadvantages of RAM: the high price of the devices, the strongly limited capacity and the problematic scaling.

Nevertheless, a solution exists. It is a new mixing technology of VibroSonic based on the effects of nonlinear dynamics and uses the solid non-uniform oscillation spectrum (SOS). SOS mixing technology provides peaks of accelerations of 1000G (x10 vs RAM) and over.

SOS mixers have all of the advantages of RAM technology, are free of the disadvantages of both conventional and Resodyn mixers and also have additional technological capabilities.

SOS mixing technology is a result of more than 30 years of research of strongly nonlinear dynamic systems. VibroSonic has a universal mixing and/or grinding device having both batch and continuous modifications.

SOS mixers are the best instruments for mixing nanoparticles.
