Useful information
A processing time of a few minutes is usually sufficient to pro-
duce the desired fineness. Long prccessing times bring only in-
significant improvements in the obtainable fineness; the energy
expended serves merely to increase the temperature of the me-
dium. Dispersion is the dissolution and diffusion of a solid, liquid or
gaseous phase in a liquid that is not consolute with that phase.
T he rotor/ stator priciple
Due to the high rotation speed of the rotor, the medium to be
processed is automatically drawn axially into the dispersion head
and then forced radially through the slots in the rotor/stator ar-
rangement.
The high accelerations acting on the material produce extremely
strong shear and thrust forces. In addition, high turbulence oc-
curs in the shear gap between rotor and stator, which provides
optimum mixing of the suspension.
The dispersion effectiveness is heavily dependent on the product
of the shear gradient and the time the particles spend in the
shear zone. The optimum range for the circumferential velocity
of the rotor/stator arrangement is 10 to 24 m/s.

The safety of the user cannot be guaranteed if the appliance is
operated with accessories that are not supplied or recommended
by the manufacturer or if the appliance is operated improperly
contrary to the manufacturer’s specifications or if the appliance
or the printed circuit board are modified by third parties.
The unit is suitable for use in all areas apart from domestic areas
and areas directly connected to a low-voltage supply which also
serves domestic areas.
