7.1. GENERAL

The Star-Beater is a high performance product. Because of the large selection of
accessories, the Star-Beater is a machine with many different application possibilities in
laboratories, industry and research. It is used mainly in the chemical and pharmaceutical
sectors and in mineralogical and biological applications etc.

7.2. MILLING PROCES

Clamp the milling jars, filled with material to be milled and the milling balls, in the milling jar
holders as described.
Starting the milling process:
• Close the hood.
• Set the time.
• Set the frequency.
• Start the milling operation by pressing the START/STOP key.
• The milling time starts running and the remaining milling time is shown on display.
The milling process can only be started, when the hood is closed.
In order to ensure quiet running of the Star-Beater, both milling positions have
to be loaded with approximately the same mass.
Do not open the hood during the milling process.
Although the milling jars are brought to a standstill immediately after the
opening of the hood, the milling process can no longer be continued with the
remaining running time.
The Star-Beater must be restarted and the initial parameters are then
available again.
Do not mill inflammable or explosive samples!
Please note that the properties and therefore the dangerous nature of your
sample, can change during the milling process.
