Safety informaon and use
2 Safety informaon and use
2.1 Requirements for the user
This operang manual is intended for persons assigned with operang and mon-
itoring the Fritsch PULVERISETTE 29. The opera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 PULVERISETTE 29.
People with health problems or under the inuence of medicaon, drugs, alcohol
or exhauson must not operate this device.
The PULVERISETTE 29 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 qualied personnel. Qualied per-
sonnel 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 opera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 PULVERISETTE 29 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 performed 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
NOTICE
This laboratory instrument is designed for an 8-hour shi oper-
aon at 30 % duty cycle and not for connuous operaon.
The duty cycle is dened as the rao of load duraon to run
me. The run me is dened as load duraon plus pause me.
According to DIN EN 60034-1 (VDE 0530, IEC34-1) a connuous
operaon already takes place aer a standardised run me of
10 minutes. At 30 % duty cycle (DC = rao of load duraon to
run me) a load duraon of 3 minutes and a pause me of 7
minutes would be within standard.
If the standardised run me of 10 minutes is exceeded, then,
by denion, there would be a connuous operaon and
disproporonate temperature increases may occur, possibly
involving increased wear.

Safety informaon and use
The Mini - Cung Mill can be used for the fast comminuon of so, medium-
hard, brile, tough and brous materials like:
Sheet rubber, plascs, refuse-derived fuel, dry meat, leather, wood, coal, malt,
paper/cardboard, peat, animal feed, pasta, tablets, leaves, pellets, spices, fabric,
straw, maize, bones, roots, tobacco...
2.2.1 Operang principle
The material is fed into the cung chamber via a funnel. There, rotang knives
(13) in combinaon with xed knives (8) cut the material. The nely cut material
falls through a sieve cassee (7) into the collecng vessel (6).
2.3 Obligaons of the operator
Before using the PULVERISETTE 29, this manual is to be carefully read and
understood. The use of the PULVERISETTE 29 requires technical knowledge; only
commercial use is permied.
The operang personnel must be familiar with the content of the operang
manual. For this reason, it is very important that these persons actually receive
the present operang manual. Ensure that the operang manual is always near
the device.
The PULVERISETTE 29 may exclusively be used within the scope of applicaons
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 funconal capability of the PULVERISETTE 29 and for any damage
or injury arising from failure to full this obligaon.
By using the PULVERISETTE 29 the customer agrees with this and recognizes
that defects, malfuncons or errors cannot be completely excluded. To prevent
risk of damage to persons or property or of other direct or indirect damage,
resulng from this or other causes, the customer must implement sucient and
comprehensive safety measures for working with the PULVERISETTE 29.
Neither compliance with this manual nor the condions and methods used
during installaon, operaon, use and maintenance of the PULVERISETTE 29
can be monitored by Fritsch GmbH. Improper execuon of the installaon 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 installaon, improper operaon or improper use or improper mainte-
nance or are in any way connected to these.
The applicable accident prevenon guidelines must be complied with.
Generally applicable legal and other obligatory regulaons regarding environ-
mental protecon must be observed.
