6.6 Mass balance
Click on the following link to watch a step-by-step video guide on how to
adjust the counterweight. Click here.
The counterweight (6) has to be positioned according to the scale in
order to offset the imbalance and thus prevent the mill from shifting.
The weight indicated on the scale is the weight of the filled grinding bowl
with the lid on.
NOTICE!
It may be necessary to readjust the mass balance if the
bowls are heavy or the speeds are high.
NOTICE!
Extra weights, like "GTM" and "additional clamping
system", have to be balanced as well.
6.7 Grinding duration
CAUTION!
Burn hazard!
Grinding bowls can get very hot after long grinding
durations. Wear protective gloves for removal after
grinding or during the grinding breaks.
Depending on the application, the grinding time should be adapted to
the development of heat in the bowls. The internal bowl temperature
can be much higher than the outside wall temperature. A guide value for
the ratio of grinding time to pause time is 1 to 3. This means that if the
grinding time is one minute, you must allow for a 3-minute pause time. If
liquids are used, the guide value is shifted towards pause times. Here the
guide value goes in the direction of one minute grinding time and 10
minutes pause time!
CAUTION!
The outer wall of the grinding bowl must not exceed 80
°C.
The longest grinding time is therefore based on the
maximum bowl temperature. The grinding time at
which this temperature is not exceeded depends very
much on the material, the balls and the speed of rota-
tion and must therefore be determined by the user
through experimentation.
