Useful information
Dispersion is the dissolution and diffusion of a solid, liquid
or gaseous phase in a liquid that is not consolute with that
phase.
The rotor/stator principle:
Due to the high rotation speed of the rotor, the medium
to be processed is automatically drawn axially into the dis-
persion head and then forced radially through the slots in
the rotor/stator arrangement. The high accelerations acting
on the material produce extremely strong shear and thrust
forces. In addition, high turbulence occurs 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 cir-
cumferential velocity of the rotor/stator arrangement is
6–24 m/s.
A processing time of a few minutes is usually sufficient to
produce the desired fineness. Long processing times bring
only insignificant improvements in the obtainable fineness;
the energy expended serves merely to increase the tempera-
ture of the medium.
The speed is set by using the operating knob. The motor
speed can be read from the LED display. For example, a val-
ue of 13.6 corresponds to 13600 rpm.
The drive unit opens up a wide range of possibilities for dis-
persion technology in the conventional laboratory with a
respective performance output of approximately 400 watts
at 25000 rpm.
