The grinding process of the device is effected through cutting and, in reverse
operation, through impact effect.
The cutters are straight and are arranged at right-angles to the direction of rotation.
The cutters are slim with a cutting angle of 15° and a pre-cut (pre-grind) of 30°.
With this cutting geometry the entire inertia resulting from the speed difference
between the sample material particles and the cutters can be used as cutting force.
The speed is between 2000 - 10000min-1 and is altered in stages of 500min-1 and
displayed digitally.
The preselected speed is kept constant during grinding by a speed regulator.
Interval operation has proved to be advantageous in the pre-grinding and
homogenisation of large-piece, tough, fibrous and very soft and elastic products.
The grinding duration can be set up to 3 minutes. After expiry of the grinding
duration the motor automatically switches off and the housing lid opens.
3 memories permit the storage and retrieval of frequently used speed/time
combinations by the press of a button.

The grinding chamber of this device is interlocked by a resistant protective hood.
It is only possible to start the device when the protective hood is closed. The motor
must have come to a standstill to open the device.
In the event of fault there is also an electric emergency brake which brings the
cutters to a standstill in fractions of a second from the highest speed.
If the achievable current speed deviates from the setpoint speed by more than 5%
due to an overload, this is shown by flashing displays.
