Working with the Planetary Micromill
Warning!!!
Before starting the machine, ensure that the grinding bowl is correctly braced
and there are no loose parts inside the device. There is a risk that loose grind-
ing bowls or parts will be thrown out.
guarantee or claims will be accepted for damages to the device or injuries to
persons.
Caution!!!
The grinding tools are subject to normal wear. Prior to each comminution the
thickness of the grinding bowl wall is to be inspected. With severe wear the
grinding bowl is to be changed. If not, the possibility exists that the grinding ball
due to high centrifugal forces which occur during the grinding may strike
through the grinding bowl wall, damaging the mill. We don’t honour the warran-
ty or accept complaints for instrument damage or personal injuries occurring
when disregarding the above information.
NOTE
During milling, high temperatures can build up in the grinding
bowl.
In encased grinding bowls, the inserts are glued into the cas-
ing with a two-component construction adhesive.
The adhesive is temperature-resistant up to approx. 140°C.
Above 140°C, the adhesive becomes liquefied and collects
below the insert in the casing. When the adhesive cools
down, it solidifies again and presses the casing upward. As a
result, the insert could get damaged. This always makes the
grinding bowl unusable.
At temperatures above 200°C, the adhesive is ruined. The
same applies for encased grinding bowl lids.
