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 PULVERISETTE 5.
People with health problems or under the influence of medication,
drugs, alcohol or exhaustion must not operate this device.
The PULVERISETTE 5 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 PULVERISETTE 5 or
other material property must be rectified immediately. The following
information serves both the personal safety of operating personnel as

2.2.1 Operating principle
Safety information and use
The grinding stock is crushed and ground by grinding balls in 2 or 4
grinding bowls. The centrifugal forces from the rotation of the grinding
bowls around their own axis and from the rotating support disc act on
the contents of the grinding bowl which consists of material to be
ground and grinding balls.
The grinding bowl and the support disc have opposite directions of rotation, so that the centrifugal forces alternate in the same direction and in
the opposite direction. The result is that the grinding balls run down the
inside of the bowl's wall as friction effect and the grinding balls hit the
opposite wall of the grinding bowl as impact effect. The impact effect is
amplified by the impact of the grinding balls against each other.
The loss-free comminution, even when grinding suspensions, is ensured
by the hermetic seal between the grinding bowl and the lid.
a Rotation of the grinding bowl
b Centrifugal force
c Movement of the support disc
2.2.2 Drive motor and speed regulation
A maintenance-free three-phase motor operated via a frequency converter is used as the drive.
