Requirements for the user
2.1
This operating manual is intended for persons assigned with operating
and monitoring the Fritsch PULVERISETTE 13 classic line. The operating
manual and especially its safety instructions are to be observed by all
persons working on or with this device. In addition, the applicable rules
and regulations for accident prevention at the installation site are to be
observed. Always keep the operating manual at the installation site of
the PULVERISETTE 13 classic line.
People with health problems or under the influence of medication,
drugs, alcohol or exhaustion must not operate this device.
The PULVERISETTE 13 classic line may only be operated by authorised
persons and serviced or repaired by trained specialists. All commissioning, maintenance and repair work may only be carried out by technically qualified personnel. Qualified personnel are persons who, because
of their education, experience and training as well as their knowledge of
relevant standards, regulations, accident prevention guidelines and operating conditions, 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 defined for skilled workers in IEC 364.
In order to prevent hazards to users, follow the instructions in this
manual.
Malfunctions that impair the safety of persons, the PULVERISETTE 13
classic line or other material property must be rectified immediately. The
following information serves both the personal safety of operating personnel as well as the safety of the products described and any devices
connected to them: All maintenance and repair work may only be performed by technically qualified personnel.
Safety information and use
2.2 Scope of application
This operating manual is not a complete technical description. Only the
details required for operation and maintaining usability are described.
Fritsch has prepared and reviewed this operating manual with the
greatest care. However, no guarantee is made for its completeness or
accuracy.
Subject to technical modifications.
PULVERISETTE 13 classic line is a disk mill for fine grinding by batches or
continuous fine grinding of hard-brittle to medium-hard solids from the
fields of mining and metallurgy, geology and mineralogy, and the glass
and ceramics industry.
The feed size maximum is 20 mm per edge; the final fineness that can be
achieved ranges from approx. 12 mm (greatest gap width) to 0.1 mm
(smallest gap width) depending on the set gap width.
- 7 -
Safety information and use
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
2.2.2 Drive motor
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
Ä
voltage, 421 - 505 rpm, see
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 determines 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 prevents dust from escaping. A dust exhaust system can be attached optionally. For cleaning, the front housing is released with the latch (9) and
swivelled open horizontally, providing access to the grinding chamber.
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.

observe this instruction can compromise the safety of the machine.
n Accident-proof conduct is to be strictly followed during all work.
n Comply with all currently applicable national and international acci-
dent prevention guidelines.
CAUTION!
Wear hearing protection!
If a noise level of 85 dB(A) is reached or exceeded, ear protection should be worn to prevent hearing damage.
WARNING!
The maximum accepted concentration (MAC) levels of the
relevant safety guidelines must be observed; if necessary,
ventilation must be provided or the machine must be operated under an extractor hood.
DANGER!
Explosion hazard!
– When grinding oxidizable substances, e.g. metals or
coal, there is a risk of spontaneous combustion (dust
explosion) if the share of fine particles exceeds a certain percentage. When grinding these kinds of substances, special safety measures must be taken and the
work must be supervised from a specialist.
–
The PULVERISETTE 13 classic line is not explosion protected and is not designed to grind explosive materials.
n Do not remove the information signs.
NOTICE!
Immediately replace damaged or illegible information signs.

Protective equipment
2.6
Safety information and use
n Unauthorised alteration of the PULVERISETTE 13 classic line will void
Fritsch's declaration of conformity to European directives and void
the guarantee.
n Only use the PULVERISETTE 13 classic line when it is in proper
working order, as intended and in a safety- and hazard-conscious
manner adhering to the operating manual. In particular, immediately
rectify any malfunctions that could pose a safety hazard.
n If, after reading the operating manual, there are still questions or
problems, please do not hesitate to contact our specialised personnel.
Protective equipment is to be used as intended and may not
be disabled or removed.
All protective equipment is to be regularly checked for
integrity and proper functioning.
The disk mill features many safety devices:
1. The funnel (1) is protected against being reached into by a grid.
2. A safety switch (4) monitors the closing of the grinding chamber
before operation and prevents the disk mill from starting up when
the chamber is open.
3. A second safety switch (6) monitors the closing of the grinding
stock container during operation and prevents the disk mill from
starting up when the container is open.
CAUTION!
The grinding stock container and the grinding chamber are
not locked by the safety switches.
The disk mill does not start up when the grinding chamber is
open or the grinding stock container is missing. If the
grinding mill is already running when one of these occurs, it
will stop.
