Dispersions and Grinding with Sonic Equipment |

Our Sonolator Homogenizing Systems have been used in all the major industries to form superior dispersions on a continuous basis. We use the power of fluid acceleration, cavitation and high pressure to dramatically reduce solid particle sizes and create extremely stable dispersions. The Sonolator, seen here, houses a specially engineered Orifice and Blade that subject material to high pressure and cavitation. A PD pump, instrumentation, controls and PLC are used to make a complete homogenizing system. The Sonolator has been used to disperse a range of solids including fumed silica, zinc oxide, titanium dioxide (TiO2), polymers, fillers, flavorings, gums and much more. |

Our Colloid Mills have been used in all the major industries to form superior dispersions and grinds on a continuous basis. We use the power of mechanical shear to dramatically reduce solid particle sizes and create very stable dispersions. The RotoMill, seen here, houses a specially engineered Rotor that turns at high speed within a stationary Stator; process fluids are subjected to intense hydraulic shear as they pass through the gap. Colloid Mills have been an industry standard for dispersing greases, silicas, TiO2, zinc oxide and more. Our Colloid Mill is leading the industry in design innovations and is definitely the best in its class. With improved bearing and seal life via a specially designed removable chamber, the stability and reliability of this mill are unmatched! |

A
Dispersion is a mixture of a solid within a fluid where the solid
exists as particles, of microscopic or ultramicroscopic size, distributed
throughout the liquid. Typically solids do not remain stable
within a fluid and separation occurs quickly; solids will remain in
suspension by their own free will if they are small enough for gravity
to be compensated for by the kinetic energy present within the mixture.
Mechanical means such
as agitation, fluid acceleration, cavitation, vibration, shaking or
excessive direction change will help reduce particle sizes of the solids
so that it remain in suspension. Sonic's purpose
is to develop equipment that will form dispersions for you with
sub-micron particle sizes and uniform particle size distributions that don't
separate readily and possess enhanced shelf life and stability.
Even finely dispersed solids over time will agglomerate, coagulate or
flocculate into larger particles, or coagula or flocs. Our
equipment is also used to eliminate these larger formations.
