Safety information and use

1.2.1 Operating principle
a Rotation of the grinding bowl
b Centrifugal force
c Rotation of the support disc
The source material is crushed and ground by grinding balls in a grinding
bowl. The centrifugal forces from the rotation of the grinding bowls
around their own axis and from the rotating support disc have an effect
on the contents of the grinding bowl, consisting of material to be ground
and grinding balls.
The grinding bowl and the support disc have opposite directions of rota-
tion, in order that the centrifugal forces alternate in the same direction
and in the opposite direction.
The result is that the grinding balls run down the inside of the bowl's wall
with a friction effect and the grinding balls hit the opposite wall of the
grinding bowl with an impact effect.
1.2.2 Drive motor and speed regulation
A maintenance-free electric motor operated via frequency converter is
used as the drive.
