Where does the
compactability of your
sand need to be
constant?
The success factors – Part 1
VEDIMAT
The fully automatic online sand-testing system
Do you measure the compactability values in the
laboratory or at the mixer only? If that is the case, then
you are wasting an opportunity to improve your casting
quality and reduce scrappage. The VEDIMAT controls
and regulates compactability and measures the
compression strength directly in front of the moulding
machine because this is the point at which the quality
of your moulding sand should be at its peak.
� The ideal place for installation
Keeping compactability constant at the mixer is not very helpful. This does not
identify or take cognisance of negative factors that affect the sand when it is
being transported to the moulding machine. A combination of the VEDIMAT and
the MICOMP UNI type G-CH systems reliably registers and compensates for
these changes (e.g. fluctuations in temperature, evaporation and bentonite
saturation effects) so that constant, high quality mechanical sand properties are
achieved at the point where they are really needed – on the moulding line.
� Networking a high-precision moisture measurement and control system
As a compactability correction factor, sand moisture is a very important issue.
Moisture fluctuations of one tenth at the mixer outlet can have a direct influence
on compactability amounting to ±2-3% on the moulding line. So if you want to
keep compactability constant within a narrow band, you need a moisture
measurement and control system that measures and controls precisely within a
few hundredths.
