Useful information
Dispersion refers to the dissipation and scattering of a solid, liquid or
gaseous phase in a liquid which cannot be fully mixed with this phase.
The rotor/stator principle:
Due to the high rotation speed of the rotor, the medium to be pro-
cessed is automatically drawn axially into the dispersing 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 circumferential velocity of the rotor/stator
arrangement is 6-20 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 temperature of the medium.
Assembly of clamp and stand
Assembly (see Fig. 1 and Fig. 2)
• Push the clamp (6) as shown in Fig. 1 over the dispersion in-
strument, until it engages in the position planned for it audibly.
• Tighten the turning handle (5) by hand until to stop.
• Screw the clamp (6) by means of cross sleeve (7) onto the stand (8).
For safe working the drive units should be fastened by means of
a cross sleeve to the plate stand. Pay attention when assembling
the dispersion instrument to the stand to a perfect and firm seat
of the cross sleeve.
In order to increase the stability of the mechanical structure, the drive
unit must be installed as closely as possible to the stand support rod.
Drive
The open up a wide range of possibilities for dispersion technology in
the conventional laboratory with a respective performance output of
approximately 75 watts at 30.000 rpm.
