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 monitoring the Fritsch PULVERISETTE 19. 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 regu-
la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 PULVERI-
SETTE 19.
People with health problems or under the inuence of medicaon,
drugs, alcohol or exhauson must not operate this device.
The PULVERISETTE 19 may only be operated by authorised persons and
serviced or repaired by trained specialists. All commissioning, mainte-
nance and repair work may only be carried out by technically 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 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 19 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 operaon at 30 % duty cycle and not for conn-
uous 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.
The Universal 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 through a funnel (example in image with standard
funnel) into the cung chamber. There, rotang knives (10) in combina-
on with xed knives (2,4,12) cut the material. The ne ground material
falls through a sieve cassee (9) into the collecng vessel (5).
For ne comminuon, the Fritsch high-performance cyclone separator
(oponal accessory 19.1900.00) can be used for the sample exhauson.
