6.5.2 Clamping the 80 ml grinding bowls
There are two ways of clamping an 80 ml grinding bowl:
1.
Place the reducer (o) (order no. 90.1120.09) into the grinding bowl
holder and position the 80ml grinding bowl on it and fasten with
the Safe-Lock tensioning device.
2. Alternatively, clamp two 80 ml grinding bowls on top of one
another.
Tensioning with the Safe‐Lock system proceeds as described
in Ä Chapter 6.5.1 ‘Clamping with the "Safe‐Lock" (5) ten‐
sioning device’ on page 35.
6.6 Mass balance
Load the laboratory planetary mill symmetrically.
Always clamp an equally heavy grinding bowl with lid and seal ring in the
opposite grinding bowl holder to balance the weight!
Failing that, select an empty bowl as a counterweight. The empty bowl
may be filled with sand as an additional weight.
NOTICE!
Extra weights, like "GTM" and "additional clamping
system", have to be balanced as well.
6.7 Grinding duration
WARNING!
Burn hazard!
Grinding bowls can get very hot after long grinding dura-
tions. Wear protective gloves for removal after grinding or
during the grinding breaks.
