Homogenizer Recommended for Dispersing Aerosil Fumed Silica

Home/Homogenizer, Process Systems/Homogenizer Recommended for Dispersing Aerosil Fumed Silica

The Sonolator homogenizer has been used for years to disperse fumed silica into resin. In fact, the Sonolator is so effective that it is mentioned by name in Evonik’s literature for their fumed silica product Aerosil. See an image of the Evonik website below:

Fumed silica is very difficult to wet out and in the process of wetting out of the fumed silica agglomerates are formed. The Sonolator homogenizer is an excellent tool for de-agglomerating the fumed silica in thick resin. While there are other device categories mentioned the Sonolator is listed by name in the literature of this major supplier of fumed silica. Sonic has homogenizer systems all over the world dispersing fumed silica into resin. Manufacturers often use an in tank rotor/stator device to first wet out the fumed silica, then the material final dispersion/de-agglomeration is performed through the orifice and blade arrangement in the Sonolator homogenizer.

Below is an image of our latest fumed silica dispersing rig built for one of our customers in China. This system is operating at 100 gallons per minute (378 liters/min.) and up to 400 PSI (27 Bar). Sonic has installed Sonolators literally all over the world to disperse fumed silica into resin.

The system before the one pictured above was installed in a manufacturing facility in Turkey and operates at 60 GPM (227 liters/min) and up to 400 PSI (27 Bar). Sonic custom designs and builds all Sonolator systems, so we can build the fumed silica dispersion units to meet a customers specific production goals (i.e.: flowrate and pressure).

Sonic is always pleased to have third party manufacturers endorse the Sonolator. Over 50 years of custom manufacturing high quality mixing systems does not go unnoticed! Call us today with your mixing and processing challenges so that we can begin to custom design a mixing solution for your operations.
