This operang manual is intended for persons assigned with operang
and monitoring the Fritsch the PULVERISETTE 13 premium line. The oper-
ang manual and especially its safety instrucons are to be observed by
all persons working on or with this device. In addion, the applicable
rules and regulaons for accident prevenon at the installaon site are
to be observed. Always keep the operang manual at the installaon site
of the the PULVERISETTE 13 premium line.
People with health problems or under the inuence of medicaon,
drugs, alcohol or exhauson must not operate this device.
The the PULVERISETTE 13 premium line may only be operated by author-
ised persons and serviced or repaired by trained specialists. All commis-
sioning, maintenance and repair work may only be carried out by techni-
cally qualied personnel. Qualied personnel are persons who, because
of their educaon, experience and training as well as their knowledge of
relevant standards, regulaons, accident prevenon guidelines and oper-
ang condions, are authorised by those responsible for the safety of the
machine to carry out the required work and are able to recognize and
avoid possible hazards as dened for skilled workers in IEC 364.
In order to prevent hazards to users, follow the instrucons in this
manual.
Malfuncons that impair the safety of persons, the the PULVERISETTE 13
premium line or other material property must be reced immediately.
The following informaon serves both the personal safety of operang
personnel as well as the safety of the products described and any devices
connected to them: All maintenance and repair work may only be per-
formed by technically qualied personnel.
This operang manual is not a complete technical descripon. Only the
details required for operaon and maintaining usability are described.
Fritsch has prepared and reviewed this operang manual with the
greatest care. However, no guarantee is made for its completeness or
accuracy.
Subject to technical modicaons.
2.2 Scope of applicaon
The PULVERISETTE 13 premium line is a disk mill for ne grinding by
batches or connuously ne grinding of hard-brile to medium-hard
solids from the eld of mining and metallurgy, geology and mineralogy,
and the glass and ceramics industry.
The feed size maximum is 20 mm per edge; the nal neness that can be
achieved ranges from about 12 mm (greatest gap width) to 0.05 mm
(smallest gap width) depending on the set gap width.
Safety informaon and use
- 7 -

The material throughput of the disk mill lies in the range of 20 to 150
kg/h. This depends on the seng of the output gap as well as the bulk
weight and the comminuon characteriscs of the sample.
2.2.1 Operang principle
The comminuon 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 lled through a lockable funnel into the centre of
the xed grinding disk and is ejected aer comminuon from the gap
between the two disks by pressure or shear stress. The gap width deter-
mines the mean parcle 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 con-
trol 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
construcon prevents dust from escaping. A dust exhaust system can be
aached oponally. For cleaning, the front housing is swivelled open
horizontally, providing access to the grinding chamber.
