The application of mechanical stress breaks the particle Agglomerates apart.
Agitators and stirrers will wash the surface of such Agglomerates, only.
Hielscher ultrasonic reactors can handle larger and abrasive particles or Agglomerates.
It absorb water easily and Agglomerates in the air, but does not deliquesce.
The obvious tailing to the right, results from the material composition(Agglomerates and larger primaries).
While the Agglomerates are reduces easily, it
takes longer processing to grind down larger primary particles.
Hielscher ultrasonic homogenizers break powder Agglomerates in liquids that conventional agitators
and high shear mixers cannot break.
Kusters et al.(1994) investigated the ultrasonically assisted fragmentation of Agglomerates in relation to its energy consumption.
Ultrasound is a reliable tool to destroy Agglomerates and to create conditions where the primary particles
are hold in.
Sonication of the adsorbant in the solvent eliminates Agglomerates within a few seconds and prepares a uniform, easily packed column.
Twin taper forced
feeding is adopted for mixed metal Agglomerates, this feeding method is more efficient
than traditional double wrist feeding method.
Ultrasonic cavitation and
shear forces couple the required energy into the suspension so that Agglomerates are broken,
van the Waals forces overcome and the abrasive nanoparticles uniformly distributed.
When mixing dry powders, such as, pigments, thickeners or gums with liquids,
the powder particles tend to form Agglomerates, lumps or so-called“fish-eyes”(partially hydrated powder with a dry powder core).
