According to DIN EN 60034-1 (VDE 0530, IEC34-1) a connuous
operaon already takes place aer a standardised run me of
10 minutes. At 30 % duty cycle (DC = rao of load duraon to
run me) a load duraon of 3 minutes and a pause me of 7
minutes would be within standard.
If the standardised run me of 10 minutes is exceeded, then,
by denion, there would be a connuous operaon and
disproporonate temperature increases may occur, possibly
involving increased wear.

The planetary micro mill, "PULVERISETTE 7 premium line", can be applied univer-
sally for the fast dry or wet grinding of inorganic and organic samples for analysis,
quality inspecon or material tesng.
During synthesis, the planetary micro mill is used for mixing and homogenizaon
of dry samples, emulsions or suspensions.
The planetary micro mill, premium line , described here is an equipment item for
use in industrial environments.
The device may be used for these purposes only.
1.2.1 Operang principle
aRotaon of the grinding bowl
b Centrifugal force
cRotaon of the support disc
The source material is crushed and ground by grinding balls in a grinding bowl.
The centrifugal forces from the rotaon of the grinding bowls around their own
axis and from the rotang support disc have an eect on the contents of the
grinding bowl, consisng of material to be ground and grinding balls.
The grinding bowl and the support disc have opposite direcons of rotaon,
in order that the centrifugal forces alternate in the same direcon and in the
opposite direcon.
The result is that the grinding balls run down the inside of the bowl's wall with
a fricon eect and the grinding balls hit the opposite wall of the grinding bowl
with an impact eect.
1.2.2 Drive motor and speed regulaon
A maintenance-free electric motor operated via frequency converter is used as
the drive.
