toring the Fritsch PULVERISETTE 6. 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 6.

People with health problems or under the inuence of medicaon, drugs, alcohol

or exhauson must not operate this device.

The PULVERISETTE 6 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 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 guide-

lines 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 6 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.

Safety informaon and use

2.2 Scope of applicaon

NOTICE

Fritsch laboratory mills are not intended for use in explosion-

hazardous areas. Fritsch laboratory mills therefore fall outside

the scope of the 94/9/EC Direcve, but within the scope of

the Machinery Direcve 2006/42/EC. The use of Fritsch labora-

tory mills within explosion-hazardous areas is not permissible

according to ATEX (94/9/EC) and is only allowed if addional

explosion protecon measures are taken. According to the

Machinery Direcve 2006/42/EC, there are no ignion sources

in our mills that can become eecve during normal operaon.

Nonetheless, there may be ignion sources in our mills that

may become eecve in the event of probable malfuncons.

Because Fritsch has only limited informaon on the composi-

on of the ground product in use, its nal neness and there-

fore ulmately its ignion temperature, no statement regarding

the explosion risk during intended use in conjuncon with the

occurring energy input can be made.

The occurrence of dust explosions can therefore never be

completely ruled out. The user must create an explosion pro-

tecon document in accordance with the ATEX 137 Direcve

(1999/92/EC) and dene appropriate protecve measures.

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.

The Planetary mono mill PULVERISETTE 6

classic line

can be applied universally

for the fast, dry or wet grinding of inorganic and organic samples for analysis,

quality inspecon, material tesng or mechanical alloying. During synthesis, the

PULVERISETTE 6 mixes and homogenises dry samples, emulsions or suspensions.

2.2.1 Operang principle

The grinding stock is crushed and ground by grinding balls in a grinding bowl. The

centrifugal forces resulng from the rotaon of the grinding bowls around their

own axes and from the rotang support disc (14) inuence the contents of the

grinding bowl consisng of grinding stock and grinding balls.

10

Safety informaon and use

The grinding bowl and the support disc (14) have opposite direcons of rotaon

so that the inuence of the centrifugal forces is alternately in the same direcon

and in the opposite direcon. The result is that the grinding balls run down the

inside of the bowl's wall as fricon eect and the grinding balls hit the opposite

wall of the grinding bowl as impact eect. The impact eect is amplied by the

impact of the grinding balls against each other.

The loss-free comminuon, even when grinding suspensions, is ensured by the

hermec seal between the grinding bowl and the lid.

2.2.2 Drive motor and speed regulaon

A maintenance-free three-phase motor operated via a frequency converter is

used as the drive.

2.3 Obligaons of the operator

Before using the PULVERISETTE 6, this manual is to be carefully read and under-

stood. The use of the PULVERISETTE 6 requires technical knowledge; only com-

mercial 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 6 may exclusively be used within the scope of applicaons set

and ammable can be spontaneously produced! The user

must rule out such a reacon before grinding.

■Do not remove the informaon signs.

NOTICE

Immediately replace damaged or illegible informaon signs.

■Unauthorised alteraon of the device will void Fritsch's declaraon of con-

formity to European direcves and void the guarantee.

■The PULVERISETTE 6 should only be used when it is in proper working order,

as intended and in a safety- and hazard-conscious manner adhering to the

operang manual. In parcular, immediately recfy any malfuncons that

could pose a safety hazard.

■If, aer reading the operang manual, there are sll quesons or problems,

please do not hesitate to contact our specialised personnel.

■Do not reuse damaged accessories.

■Do not leave the Planetary mono mill running for several hours without

4.1 Transport

The device is delivered on a transport pallet with a wooden cover. We recom-

mend using a forkli or pallet truck for transporng the packed device.

DANGER

Do not step under the transport pallet during transport.

WARNING

Improper liing can lead to personal injury or property

damage. The machine is only to be lied with suitable equip-

ment and by qualied personnel.

The guarantee excludes all claims for damage due to improper transport.

4.2 Unpacking

■Remove the nails that fasten the wooden hood to the transport pallet.

■Li the hood o the transport pallet.

■The pre-perforated segments can be detached so that the foam parts can be

removed more easily.

■Please store the transport packaging so that it can be reused if you need to

return the product. Fritsch GmbH accepts no liability for damage caused by

improper packaging (packaging that is not from Fritsch).

■Compare the contents of the delivery with your order.

Grinding bowls made of hardened steel may have recesses on

the surface caused during producon. They do not have an

impact on grinding or the grinding results and usually disap-

pear aer the rst grinding operaon.

These recesses on the surface, if present, are within the range

of the permissible producon tolerances. Complaints relang

to such grinding bowls therefore cannot be accepted.

4.3 Seng up

NOTICE

Allow the device to acclimase for two hours before commis-

sioning. High temperature dierences can lead to condensaon

in the device and damage to the electronics aer switching on.

Strong temperature uctuaons can occur during transport or interim storage.

Depending on the temperature dierence between the installaon site and the

transport or storage environment, condensaon can form inside the device. This

can damage the electronics if the devices are switched on too early. Wait for at

least two hours aer setup before switching on the device.
