Safety
The ZM200 is a modern, high-performance product
manufactured by Retsch GmbH. It incorporates the latest
technology. The machine is entirely safe in its operation
when used for the intended purpose and in accordance
with the present technical documentation.
Safety instructions
You, as the owner/operator, must ensure that the
persons who are entrusted to work on the ZM200:
have read and understood all the regulations contained
in the chapter on safety,
have made themselves familiar, before starting work,
with all the operating instructions and regulations rele-
vant to that particular target group,
have unrestricted access to the technical documentation
for this machine at all times,
new personnel must have familiarised themselves with
the safe use of the ZM200 and its intended purpose
before starting work with the machine, either through
verbal instruction by a competent person and / or with
the help of the present technical documentation.
Incorrect operation can result in injuries to persons and
damage to property. You bear the responsibility for your
own safety and that of your staff.
Ensure that no unauthorised persons have access to the
ZM200.
As a precaution, have your staff certify in writing that
they have received instruction in the operation of the
ZM200. A draft for such a form can be found at the end
of the chapter on safety.
We reject herewith any and all claims relating to personal injury or
material damage which result from the failure to comply with the
following safety instructions.

Safety directive summarised, part 1
Safety instructions
We reject herewith any and all claims relating to personal injury or material damage which result
from the failure to comply with the following safety instructions.
Intended use
Do not make any modifications to the machine and only use Retsch approved spares and
accessories.
The conformity to the European guidelines declared by Retsch otherwise loses its
validity. It furthermore leads to the loss of all warranty claims.
Packaging
Please retain the packaging for the duration of the warranty since, in case of complaint, returning in
unsuitable packaging can jeopardize your warranty claims.
Transport
During transportation, do not subject the ZM200 to impacts, jolts or vibrations. The electronic and
mechanical components could otherwise be damaged.
Temperature fluctuations
In case of wide temperature fluctuations (during shipment by air, for instance), protect the ZM200 from
condensation. The electronic components could otherwise be damaged.
Scope of supply
If the shipment is incomplete and / or has suffered transport damage, you must notify the forwarder and
Retsch GmbH immediately (within 24 hours). Under certain circumstances, claims lodged at a later date
may not be considered valid.
Ambient temperature :
When the ambient temperature exceeds or falls below that specified, the electronic and mechanical
components may be damaged, and performance data changed to an unknown extent.
Air humidity :
At a higher air humidity, the electronic and mechanical components may be damaged, and performance
data changed to an unknown extent.
Electrical connection / connecting the power
Failure to observe the values on the data plate can cause damage to electronic and mechanical
components.
Inserting the grinding tools
Set the openings for the torsion lock on the collecting vessel and the ring sieve over the torsion lock pin.
Otherwise the ZM200 cannot be started.
When cold grinding, do not forcibly remove the plug-on rotor, which jams easily for physical reasons, but
rather wait for the temperature to level out.
Forced removal causes damage to the motor shaft and the rotor.
Do not forget to re-install the cassette cover.
Without the cassette cover, the motor is blocked by the thrust pins in the housing cover.

Safety directive summarised, part 2
Feeding in comminution material
Do not feed in comminution material until the machine has been started.
Mechanical components could be damaged when starting from standstill with the comminution material
already fed in.
When feeding in comminution material, the anti-rebound fitting must be installed.
Danger that the comminution material will be sprayed about.
Unsuitable comminution material
Some comminution materials form explosive atmospheric mixtures. Check the properties of your
comminution material.
Explosion hazard
Dusty comminution material can escape through the filling hopper during grinding. Use suction extractors if
the comminution material is toxic or otherwise hazardous to health.
Danger of breathing in dust hazardous to health.
Comminution methods
Do not pre-grind without the ring sieve.
The collecting base can suffer serious damage
The rotor can damage the cassette cover.
Comminution by cold grinding
When cold grinding with liquid nitrogen, always fit the anti-rebound fitting Xinto the filling hopper.
Danger of injuries to eyes and skin from extreme freezing.
Wear safety gloves and goggles, The temperature of the liquid nitrogen is -196°C
Danger of injuries to eyes and skin from extreme freezing.
When cold grinding, do not forcibly remove the plug-on rotor, which jams easily for physical reasons, but
rather wait for the temperature to level out.
Forced removal causes damage to the motor shaft and the rotor.
Paper filter with retainer
The volume able to be taken up by the paper filter depends on the density of the grinding material and the
hole width of the ring sieve.
The paper filter can be destroyed by overfilling and by the weight of the comminution material
Cleaning
Do not clean the ZM200 with flowing water.
Mortal danger from electric shock
Only use a cloth dampened with water. solvents are not permitted.
Maintenance
The easy running of roller 1 on the trannion piece is essential for secure closing of the housing cover.
These operating instructions do not contain any repair instructions. In the interests of your own safety,
repairs should only be performed by Retsch GmbH, an authorised representative or by Retsch service
technicians.

Technical specifications
Machine type designation: ZM200
Intended use
The Retsch Ultra Centrifugal Mill ZM200 is deployed for rapid fine
grinding of soft to medium hard and fibrous materials up to a
grain size of 10 mm.
See the section in the chapter on "Operation" below for
examples:
"Unsuitable comminution material"
"Suitable comminution material"
"Comminution methods"
"Comminution by cold grinding"
The end fineness achievable is determined by :
The type of rotor
The speed of the rotor
The ring sieve
The shearing properties of the comminution material
The effective grinding technology and the extensive range of
accessories mean that the ZM200 can quickly prepare samples
ready for analysis in a way which preserves the material.
It is not designed as a production machine, but rather as a
laboratory device intended for single-shift, 8-hour operation.
Do not make any modifications to the machine and only use Retsch
approved spares and accessories.
The conformity to the European guidelines declared by Retsch
otherwise loses its validity.
It furthermore leads to the loss of all warranty claims.
Maximum feed quantity
Max. up to 20 ml with the collection container for
minimum quantities
The max. recommended feed quantity with the standard
collection container is 300ml, which corresponds to
approx. 1/3 of the cassette’s filling capacity. If more is
filled into the cassette, the sample and the appliance
may overheat.
Do not fill too much into the collecting container. Do not exceed a max.
1/3 of the filling capacity.
Excessive filling can cause overheating and damage to the plastic
housing.
Max. 5000 ml with components obtainable as accessories
Maximal feed grain size
Up to 10 mm
Maximal end fineness achievable
< 40 µm, in dependence on the feed material and ring sieve
Drive output
750 W / power draw approx. 1300 W
Rotor speed
Can be regulated from 6,000 –18,000 r.p.m.

01.12.2016 Retsch GmbH 10
ZM200 emissions
Noise levels :
Noise measured according to DIN 45635-31-01-KL3
The noise levels are basically influenced by the speed of
the machine, the feed material, the feed grain size, the
rotor used and the ring sieve deployed.
Workplace related emission value LpAeq = up to 77.5 dB(A)
Measuring conditions :
Machine speed = 18,000 r.p.m.
Feed material = burnt lime
Feed grain size = <5 mm
Ring sieve deployed = 0.5 mm Conidur perforation
Rotor deployed = 12-tooth rotor
