FRITSCH PULVERISETTE 6 classic line - Manual (Page 9)

2.2.1 Operating principle
The grinding stock is crushed and ground by grinding balls in a grinding
bowl. The centrifugal forces resulting from the rotation of the grinding
bowls around their own axes and from the rotating support disc (14)
influence the contents of the grinding bowl consisting of grinding stock
and grinding balls.
The grinding bowl and the support disc (14) have opposite directions of
rotation so that the influence of the centrifugal forces is alternately 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 as friction effect and
the grinding balls hit the opposite wall of the grinding bowl as impact
effect. The impact effect is amplified by the impact of the grinding balls
against each other.
The loss-free comminution, even when grinding suspensions, is ensured
by the hermetic seal between the grinding bowl and the lid.

A maintenance-free three-phase motor operated via a frequency con-
