Requirements for the user
2.1
This operating manual is intended for persons assigned with operating
and monitoring the Fritsch of the PULVERISETTE 0. 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 of the
PULVERISETTE 0.
People with health problems or under the influence of medication,
drugs, alcohol or exhaustion must not operate this device.
The of the PULVERISETTE 0 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 of the PULVERISETTE
0 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.
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.
The "Vibratory Micro Mill PULVERISETTE 0" is used for the fine comminution of dry laboratory sample material or suspensions. It is used for
homogenising emulsions or pastes.

2.2.1 Operating principle
Safety information and use
The plastic housing contains a solid cast structure with an electronically
controlled electromagnet. Three permanently flexible flat springs carry
the pole plate of this magnet together with the vibratory plate, which is
fastened to it. When the magnet is switched on, the pole plate and vibratory plate are attracted and spring back when it is switched off. The cast
structure and magnet on one side and the pole plate, vibratory plate and
sieves on the other side form a vibratory system.
The different weights of the mortar material or grinding balls change the
natural frequency of the vibratory system. For this reason, it is not
always possible to set the amplitude of the micro mill optimally e.g. with
a constant 50 Hz mains frequency present. The processor-controlled
electronics of the PULVERISETTE 0 micro mill ensure a precisely adjustable, reproducible oscillation amplitude. This is achieved by bringing the
frequency to stimulate oscillation closer to the natural frequency of the
system or farther away from it. The desired oscillation amplitude of the
grinding set between 0.1 mm and 3.0 mm can always be achieved - and
with relatively low energy input. Therefore, continuous operation is possible without heating the sample material and the overall mill system.
The mortar bowl with 50 mm diameter grinding ball (or 70 mm for agate
only) and grinding stock oscillates vertically. This causes the grinding ball
in the mortar bowl to vibrate and comminute the grinding stock by
impact and friction.
2.2.2
Amplitude control
2.3 Obligations of the operator
An electronic control circuit guides the oscillation frequency of the PULVERISETTE 0 from a high to a low frequency range. In the meantime, a
measuring system records the amplitude and reports it to the control circuit until the preselected amplitude is reached.
This amplitude control takes place at regular intervals during the entire
operation. This makes it possible to react to changes in the vibratory
system.
The amplitude of the PULVERISETTE 0 is set manually with the Plus and
Minus key on the control panel and viewed on the lid.
Before using the of the PULVERISETTE 0, this manual is to be carefully
read and understood. The use of the of the PULVERISETTE 0 requires
technical knowledge; only commercial use is permitted.
The operating personnel must be familiar with the content of the operating manual. For this reason, it is very important that these persons
actually receive the present operating manual. Ensure that the operating
manual is always near the device.

Safety information and use
The of the PULVERISETTE 0 may exclusively be used within the scope of
applications set down in this manual and within the framework of guidelines put forth in this manual. In case of non-compliance or improper
use, the customer assumes full liability for the functional capability of
the PULVERISETTE 0 and for any damage or injury arising from failure to
fulfil this obligation.
By using the of the PULVERISETTE 0 the customer agrees with this and
recognizes that defects, malfunctions or errors cannot be completely
excluded. To prevent risk of damage to persons or property or of other
direct or indirect damage, resulting from this or other causes, the customer must implement sufficient and comprehensive safety measures
for working with the of the PULVERISETTE 0.
Neither compliance with this manual nor the conditions and methods
used during installation, operation, use and maintenance of the of the
PULVERISETTE 0 can be monitored by Fritsch GmbH. Improper execution
of the installation can result in property damage and thus endanger persons. Therefore, we assume absolutely no responsibility or liability for
loss, damage or costs that result from errors at installation, improper
operation or improper use or improper maintenance or are in any way
connected to these.
The applicable accident prevention guidelines must be complied with.
Generally applicable legal and other obligatory regulations regarding
environmental protection must be observed.

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 high-speed rotor mill is not explosion protected
and is not designed to grind explosive materials.
n Do not remove the information signs.
