FRITSCH PULVERISETTE 13 classic 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. (Depending on the
voltage, 421 - 505 rpm, see Ä Chapter 3.7 ‘Speed’ on page 15)
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 adjusted and controlled from the outside.
During grinding by batches, the grinding stock is collected in a grinding
stock container inserted into the device. The closed construction pre-
vents dust from escaping. A dust exhaust system can be attached option-
ally. For cleaning, the front housing is released with the latch (9) and
swivelled open horizontally, providing access to the grinding chamber.
2.2.2 Drive motor
Drive by a 3~230 / 400 V motor.
The drive motor is a three-phase motor. Because of the drive's high
reduction ratio, the disk mill comes to a standstill very quickly when
switched off.
