of the PULVERISETTE 14 premium line.
People with health problems or under the influence of medication,
drugs, alcohol or exhaustion must not operate this device.
The PULVERISETTE 14 premium line may only be operated by authorised
persons and serviced or repaired by trained specialists. All commis-
sioning, maintenance and repair work may only be carried out by techni-
cally 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 oper-
ating 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

2.2 Scope of application
NOTICE!
The PULVERISETTE 14 premium line has been built
according to the state of the art and in accordance with rec-
ognized safety rules. During operation, however, hazards
can arise for users or third parties and damage to the
machine or other material property can occur.
The PULVERISETTE 14 premium line allows the fast comminution of soft
to medium-hard samples, such as:
Plants Wood Roots Leaves Needles Spices
Pharmaceuticals Dragées Pills Textiles Leather
Chemicals Fertilizer Food Grains Feed pellets Plastics
Pulp Filler Chalk Kaolin Coal
After embrittlement with liquid nitrogen:
Synthetic resins Foils Plastics (PVC, PP, PE)
The extremely high-speed PULVERISETTE 14 premium line enables the
comminution of temperature-sensitive ductile or plastic samples. By
simultaneously adding liquid nitrogen, samples that are extremely diffi-
cult to mill, such as soft PVC foils, can be made fine enough for analysis.
For iron-free grinding, the rotor and sieve used are made of titanium.
The inside of the mill, typically made of chrome-nickel stainless steel, has
been suitably coated with a relatively abrasion-resistant PTFE layer. The
grinding insert made of pure titanium is only for use with "soft mate-
rials". Hard substances destroy the sieve ring and drastically reduce the
service life of the rotor.
Safety information and use
- 8 -

2.2.1 Operating principle
The fast comminution capability of the PULVERISETTE 14 premium line is
due to the extremely high speed of the rotor, which is made of stainless,
tempered steel. With a rotational speed of up to 111 m sec-1, the impact
energy lies in the range of pin mills, known for their high grinding
capacity. Additionally, the sharp-edged teeth of the rotor work in combi-
nation with the installed sieve to grind the sample by shearing - similar
to high speed cutting mills. After passing through the sieve, the ground
sample is collected in a stainless collecting vessel.
The source material is fed through a funnel into the grinding chamber
and accelerated outwards radially by the high speed of the rotor. There,
the material is caught by the impact rotor, ground, and then discharged
through the sieve ring into the collecting vessel at a defined particle feed
size.
To ensure continuous flow of the sample, the vibratory feeder LABOR-
ETTE 24 is connected to the PULVERISETTE 14 premium line and the free
end of the channel is placed over the input funnel of the PULVERISETTE
14 premium line. Depending on the model, the feed rate can be regu-
lated by the mill to always feed the right amount of sample for optimal
comminution. If the amount of source material is too large, the feeder is
automatically decelerated.
2.2.2 Speed control
By tapping the number field in the "Speed" menu item, the rotational
speed can be preset to between 6000 - 22000 rpm in increments of
1000, and in this way be optimally adapted to the requirements of the
grinding of the samples. The speed is readjusted for each load.
2.3 Obligations of the operator
