FRITSCH PULVERISETTE 13 premium line - Manual (Page 8)

The material throughput of the disk mill lies in the range of 20 to 150 kg/
h. This depends on the setting of the output gap as well as the bulk
weight and the comminution characteristics of the sample.
2.2.1 Operating principle
The comminution of the material sample is done in a grinding chamber,
which is sealed dust-proof to the outside, in which two roughly meshed
grinding disks work against each other. The movable grinding disk is
driven by a powerful, slowly running gear motor.
The grinding stock is filled through a lockable funnel into the centre of
the fixed grinding disk and is ejected after comminution from the gap
between the two disks by pressure or shear stress. The gap width deter-
mines the mean particle feed size of the grinding stock. The grinding gap
can be precisely set down to 0.05 mm by the plus/minus keys on the
control panel. The gap distance can be viewed on the display (1).
During grinding by batches, the grinding stock is collected in a grinding
stock container inserted into the instrument (volume: 2 l). The closed
construction prevents dust from escaping. A dust exhaust system can be
attached optionally. For cleaning, the front housing is swivelled open
horizontally, providing access to the grinding chamber.
