  The actual dispersion system in a bead mill consists of a milling chamber and an agitator; the milling chamber is filled with the grinding beads (material glass, zircon oxide, steel) and the product to be dispersed. In the milling vessel, the grinding medium is kept moving by the agitator, which itself is driven by a motor. The dispersion process takes place between the grinding beads ...

  Technical report "Dispersion"

   · Grinding of pigments. This is achieved by using mechanical dispersing units. By high shear forces the interaction of the individual particles is resolved and thus the wetting of the particles is supported resulting in separation of the agglomerates. This stage is very susceptible to new agglomerations first and therefore it is important to stabilise it at once. Stabilisation of the .

  Grinding and Dispersing: Chemical Engineering Technology ...

  In many grinding processes, wet‐operated mills are used. An approach was derived to simulate a wet mill using a modified contact model in a discrete‐element method. The model was compared with bead‐bead simulations. The calculated bead movement could then be used to compute stress energy distributions. The gained results show that this approach is a possibility to .
