NOTE
Damage to the sieve mesh
–
An excessive accumulation of water in the sieve stack can lead to
overloading and subsequently damage or destroy the sieve mesh.
• Always restrict the dosage of water to quantities that will prevent too
much water building up .
• The use of dispersing agents is recommendable. They reduce the surface
tension in the sieve fluids.
• When working with materials that are difficult to form into a slurry or separate
accurately, spray the individual fractions one after another.
• After the sieving process, the fractions are transferred from the individual
sieves to appropriate filters (paper filter) and dried in the drying ovenat 80°
C.
• Clean the sieves in the ultrasonic bath then and dry in the drying cabinet
also (without sealing).
• Do not exceed the maximum drying temperatureof 80°C.
NOTE
Loading diagrams
–
Due to the undefinable volume of water in the sieve stack , it is not
possible to provide binding information on wet sieving.
• The loading diagrams in these operating instructions do not apply to
wet sieving.

EasySieve®, the software package from RETSCH for grain size analyses, is
superior to manual evaluation in many respects. This is because the software is
able to perform the required measuring and weighing processes automatically
–
from determining the weights of the sieves to evaluating the data. And in a much
more simple and comfortable manner
– thus making life “easier”.
The software is structured in a self-explanatory way and follows the logical chain of
events involved in analysing grain sizes. This makes it possible to use it with
confidence in a fairly short time. The multiplicity of evaluation options additionally
provides the utmost flexibility in adapting to demanding, individual applications.
