NOTICE!
The grinding disk holder and the housing are made of
spheroidal graphite cast iron. This steel cast is not stainless.
If you comminute sample material that is slightly moist,
then after the grinding, you need to dry off the back side of
the grinding disks, the inner side of the grinding disk holder
and all parts of the housing that comes into contact with
the samples. If you do not do this, then you can count of
corrosion.
8.1 Sucking off dust after a grinding
After a grinding process has ended, you can suck off the dust that has
accumulated during grinding. Install the dust extraction as described in
Ä Chapter 7.1 ‘Dust extraction’ on page 33.
NOTICE!
Do not switch the dust extraction on during grinding, as
otherwise sample material may be sucked off as well.
8.2 Grinding chamber
Open the grinding chamber to clean it. Use a narrow and/or wide brush
and a vacuum cleaner to clean out the grinding chamber. If necessary,
you can also apply liquid cleansers (alcohol, benzine). Watch for possible
corrosion though when using water-based fluids. Be sure to dry out the
disk mill thoroughly.
