Technical data
The sample quantity should not be less than 25% of the
milling cup volume.
The milling ball/s may otherwise damage the
milling cups.
The milling cup materials and milling ball materials
must always be identical.
The milling ball/s may otherwise damage the
milling cups.
Do not make any alterations to the machine and use
only spare parts and accessories approved by Retsch.
Otherwise the Declaration of Conformity with the
European directives by Retsch loses its validity.
Futhermore this will result in the loss of any kind
of guarantee claim.
Do not clamp any ceramic milling cups of the MM 2/200
or any milling cups without a complete steel casing.
Clamping by the metallic components of the
milling cup holder of the MM 400 can cause
damage to the ceramic parts.
Target group: Operating authority, operator
Machine type designation: MM 400
Use according to the intended purpose
The MM 400 is a laboratory machine and is suitable for milling
and homogenising soft, fibrous, hard and brittle materials in
the wet and dry state.
The MM 400 is designed for use with screw-type milling cups
with a steel casing and a milling set with clamping centerings
of dia. 36 mm and a min. clamping length of 60 mm. It is used
for fast, super fine milling of 2 samples simultaneously.
Ceramic milling cups without a complete steel casing must not
be used.
The closed milling system guarantees complete recovery of the
samples. Owing to the extremely short milling time and the
high final fineness of the material to be milled the MM 400 is
also ideally suitable for sample preparation for all spectral
analyses.
Final finenesses of down to 1 µm can be achieved, depending
on the milling time and the specific properties of the sample
material. The optimum milling cup filling is as a rule 1/3 of the
milling cup volume.
Exceptions to this are voluminous materials, such as wool,
leaves, grasses and suchlike. In these cases a filling level of
70-80% is necessary.
2/8/2012 9 Retsch GmbH
Do not use ceramic or natural stone milling cups for
milling graphite or graphite mixtures.
The high lubricating properties of graphite cause high
milling ball speeds, the energy of which cannot be
absorbed by the material owing to its low density.
For this reason there is a danger that the ceramic
or natural stone inserts of the milling cups will be
destroyed by the ball/s.

Inserting / replacing the milling cups
Place the milling cups, filled with the material to be milled and
the milling balls, into the centering points Z of the clamping
device and clamp firmly. Fig.1/2
Remove the locking pin SB upwards from the groove and
turn through 90°. Fig.1/2
This unlocks the locking device.
Turn the handwheel HD counterclockwise until the max.
clamping range is reached. Fig.1/2
Turn the locking pin SB back through 90° until it engages in
the groove again.
Insert milling cup and press lightly into the centering point Z
Turn the handwheel HD clockwise with two fingers until the
milling cup just fits, free of play, in the holder. Then
continue to turn the handwheel clockwise through 6 – 8
easily audible “clicks”, while at the same time the locking
pin SB is raised and lowered with clearly audible “clicks”.
The engaged locking pin reliably prevents automatic opening of
the milling cup holder.
If the locking pin SB cannot be pulled upwards to release it,
unlocking should not be forced with a hammer or similar tool.
Otherwise the hardened locking pin can break off.
Briefly retension the handwheel HD in the clockwise direction –
the locking pin can then move freely again.
To remove the milling cup lift the locking pin and turn the
handwheel in the opposite direction to tighten.
In order to guarantee quiet running of the MM 400 both milling
positions must be loaded with approximately the same mass.
Ensure that the milling cups are inserted correctly in the

Safety instructions for handling liquid nitrogen
The MM 400 is also designed for cryogenic milling.
As an accessory for cold milling we also supply a cryo kit for
cooling the milling cups with liquid nitrogen.
Cryo kit order number: 22.354.0001.
When handling liquid nitrogen always wear protective
goggles and protective gloves.
Liquid nitrogen has a temperature of – 196°C and can cause
injury similar to burns or frostbite in contact with the skin
or eyes.
Protective goggles also protect the eyes against serious
injuries through flying glass splinters, which may be caused
through bursting of glass containers as a result of low
temperature tension.
Please follow the safety regulations of the cooling
liquid supplier.
Retsch GmbH excludes any liability claims whatsoever
which may arise through the use of liquid nitrogen or
similar materials.

Safety functions
F01 - Overloading
In order to avoid overloading of the drive motor and resulting
endangerment to the user the MM 400 is fitted with a load monitoring
device.
In case of overloading the monitoring function switches the machine
off in good time.
At the end of the cooling time it is only necessary to switch the
machine off and on again in order to be able to operate it normally
again.
F02 – Speed recognition, zero speed
If the drive does not start up after pressing the start button there is a
fault in the system. Possible causes: drive blocked, motor or speed
sensor defective.
F03 – Speed recognition, overspeed
If the specified frequency is exceeded after starting, „F3” appears in
the display and the machine is switched off.
Possible cause of fault: defective speed sensor.
F04 – Hood open
The drive must not run when the hood is open. This serves to protect
the operator against injury. If the hood is opened when the machine
is running the control unit switches the drive off immediately and
“F04” appears in the display. If the start button is pressed with the
hood open in order to start the milling process “F04” is also displayed
and the drive is not started.
This alarm can be cancelled by pressing the stop button.
F05 –Keyboard monitor
If one or more buttons are pressed for longer than 15 seconds the
control unit switches the drive off and displays “F05”.
This function is intended to prevent unintentional faulty operation if
any object accidentally presses on the keyboard.
In order to cancel this fault alarm switch the machine off and on
again once.
F06 – Magnetic speed monitoring sensor
If one of the magnets that monitors speed is missing or defective,
this will be detected by the control, which will then switch off the
machine. “F06” will appear in the display. To eliminate this fault, it
must be repaired by authorised Retsch service technicians.
F07 – Magnetic switch – hood monitoring
If the magnetic switch which monitors hood opening has a defect in
the supply line this is recognised by the control unit and causes the
machine to be switched off. “F07” appears in the display. To eliminate
this fault repair by an authorised Retsch service agent is necessary.
2/8/2012 23 Retsch GmbH
General
