Mortar Grinder.
Mortar Grinder RM 200
The famous “Retsch Mill” is the classic in the product range. It was
patented in 1923 by F. Kurt Retsch and soon became the worldwide

synonym for modern lab technology as it replaced tiresome grinding
with hand mortars.
Today, RETSCH presents the latest generation of the “Retsch Mill”, the
RM 200, which continues to set the standard in this product segment.
The new RM 200 can be used for both dry and wet grinding down to a final fineness
of <10 µm. The useful volume has been increased by 40 ml compared with the
previous model.
The mill allows for efficient size reduction and homogenization of the sample due to
its advanced scraper. This ensures the removal of caked-on sample material from the
mortar walls and continuously feeds it back to the grinding process. A performance
display shows the current degree of loading of the mill, which allows the pestle
pressure to be optimized. The operation of the RM 200 has been further improved.
Both the pestle and scraper can be replaced without the use of any tools, which
makes cleaning the mill quicker and easier.

RM 200 Technology
Mortar grinders comminute, mix and homogenize by pressure and friction. The scraper feeds
the material into the area between the mortar
and pestle. This forced feed ensures that the
whole of the sample is continuously subjected to
the grinding and trituration process and is also
thoroughly mixed. The pestle is not located in the center of
the mortar but is offset; contact with the rotating mortar and the
sample causes it to rotate automatically. The necessary grinding pressure is
achieved by the weight of the pestle itself combined with the adjustable spring
pressure acting on its axis.

Planetary Ball Mill.
The New Planetary
Ball Mill PM 400
The Planetary Ball Mill PM 400 is a
robust, compact, floor model that
can process up to 8 samples
simultaneously down to final
finenesses in the submicron range.
It is particularly suitable for longterm trials, colloidal grinding and
mechanical alloying.
The new PM 400 is a real powerhouse. A selectable speed range from 30 to
-1
400 min in combination with an effective sun wheel diameter of 300 mm guarantees a high energy input and therefore analytical fineness in a very short
time. The new model now offers an even greater range of applications, combined with improved operating comfort and safety.

■ Programmable starting time – As the starting time of the grinding process
can be programmed in advance, it can also be started when the user is not
present. Thus, overnight grinding is no longer a problem.
Power failure backup – If there should be a power cut during operation the
PM 400 will save all parameters including the remaining grinding time up to
the time that the power cut occured. When the power supply is restored the
current operating status is shown and the grinding process can be resumed.
Without this information the sample would have to be rejected and the whole
grinding process started again.
■ 1-button operation with graphics display –
this feature allows the quick and easy programming of up to 10 parameter combinations in
13 languages.
The easily accessible grinding chamber of the
PM 400 is acoustically insulated and equipped with
a powerful fan which cools both the grinding
chamber and grinding jars.

Planetary Ball Mill.
Production of nanoparticles with the
Planetary Ball Mill PM 400
The production of ultrafine grinding
products requires particular stress conditions, as the smaller the size of a solid particle, the more difficult it is to
break it down by mechanical forces.
Ultrafine grinding by mechanical stress
is primarily possible in liquid media and
requires a high energy input together
with the application of pressure-shearing forces, the so-called sliding fracture. The Planetary Ball Mill PM 400
from RETSCH meets these requirements.
Applications.
The choice of grinding jars with
the suitable ball charge also has a
decisive influence on the degree of
fineness. Grinding jars and grinding
balls made from zirconium oxide
with their high abrasion resistance
are particularly suitable for ultrafine
grinding. The correct interaction
between parameter settings and
grinding jar filling is crucial in
enabling colloid grinding to be successfully carried out in the shortest
possible time.
The PM 400 is particularly suitable for
these applications.

The illustration shows the result of the ultrafine grinding of a synthetic quartzaluminum-oxide-phase. Four 500 ml zirconium oxide grinding jars were used,
60% of the jar volume were filled with 3 mm dia. grinding beads. In addition,
180 ml isopropanol was added to each jar. As wet grinding can result in overpressure in the grinding jars, the safety closing device should be used. Each grinding
jar then weighs approx. 8.5 kg. Even when the PM 400 is operated with such heavy
-1
jars it runs quietly and safely. With a sun wheel speed of 320 min in interval
operation a final fineness of d50 = 0.99 µm was achieved after only 150 minutes;
after 600 minutes this value was 0.18 µm.

The grinding jars are arranged eccentrically on the sun wheel of the planetary
ball mill. The direction of movement of the sun wheel is opposite to that of the
grinding jars in the ratio 1:-2 (or 1:-2.5 or 1:-3). The grinding balls in the
grinding jars are subjected to superimposed rotational movements, the socalled Coriolis forces. The difference in speeds between the balls and grinding
jars produces an interaction between frictional and impact forces, which
releases high dynamic energies. The interplay between these forces produces
the high and very effective degree of size reduction of the planetary ball mill.

The Vibratory Disc Mill RS 200 from RETSCH is used for the
quick, loss-free grinding of hard, brittle and fibrous
materials to analytical fineness.
In comparison to its predecessor, the RS 200 has a much
stronger motor which increases the energy input and therefore the grinding performance even further. The drive kinematics have been optimized in such a way that the grinding
results, also after short grinding times, achieve a very high
degree of reproducibility.

The operation of the new model is
much more convenient. The grinding
parameters are entered using a single
button, in addition to the current
settings a graphics display shows
service and operating information.
Up to 10 parameter combinations
can be stored and the user can choose
between 13 languages for menu
guidance. The powerful instrument
runs steadily and smoothly, even with
heavy grinding sets and at maximum
speed. The mill is acoustically insulated,
compact and stands on 4 rollers, which
make it easier to move about. It satisfies all relevant safety requirements.
A comprehensive range of grinding
sets is available for the RS 200.
In addition to materials such as special
steel, tungsten carbide, agate and
zirconium oxide, a steel version is
available for heavy-metal-free grinding. Grinding dishes with nominal
volumes of 50, 100 or 250 ml can be
used, depending on the amount of
sample. A grinding set for the Vibratory Disc Mill consists of a grinding
dish with cover which contains the
grinding tools – a disc and a ring.
The grinding sets are characterized
by the following advantages:
■ Secure seat due to built-in anti-twist
safeguards on cover and base
■ User-friendly gripping edges on
dish and cover
■ Protective jacket made from
stainless steel (for agate, zirconium
oxide and tungsten carbide sets)
■ Optimal sealing with o-ring
The grinding sets have been specially
developed for extreme trial conditions
such as high sample throughput and
high mechanical stress.

Vibratory Disc Mill.
Size reduction performance and reproducibility in comparison
Vibratory Disc Mills are designed to achieve a reproducible degree of fineness
required for spectral analyses in a short grinding time. The grinding results are
significantly influenced by the movement patterns of the free masses.
A “Quarter Minute Test” (QMT) evaluates the formation and stability of the movement patterns of Vibratory Disc Mills. The illustration shows that with the RS 200
a d90 value of 106 µm was achieved after a grinding time of only 15 seconds,
whereas under the same conditions the comparative mills only achieved d90 values of 205 µm and 278 µm.

Comparison of the size reduction performance of the RS 200 with Disc Mills from other manufacturers. All mills
were operated with maximum speed. The new, powerful Stabilized-Plane-Drive of the RS 200 allows for the
extremely rapid formation of the movement pattern inside the grinding jar which is reflected in the higher
fineness after 15 seconds.
The superiority of the drive kinematics of the new RS 200 is proven by its high
final fineness as well as its remarkable reproducibility. In another trial under the
same conditions it was ascertained that the grinding results of the RS 200 after
60 seconds show by far the smallest standard deviation.

RS 200 Technology
The Vibratory Disc Mill comminutes by pressure, impact and friction. The
grinding set is firmly attached to the vibration plate with a quick-action lever.
The plate with the grinding set is subjected to circular horizontal vibrations.
The centrifugal force acting on the grinding rings in the dish results in extreme
pressure, impact and frictional forces acting on the sample. The rotational vibrations are produced by a frequency controlled 3-phase 1.5 kW motor.
The new Stabilized-Plane-Drive ensures that the main directional movement of
the drive train is secured in a plane. This prevents the jar from gyrating or tumbling. A sensor recognizes the presence of agate grinding sets and automatically

Sample preparation for XRF
The neutral-to-analysis preparation
of the sample material is an important precondition for meaningful
X-Ray Fluorescence Analysis in which
the particle size plays a decisive
role; it should be between 20 and
60 µm. It can have a crucial influence on the analysis signal, as the
intensity of the fluorescent radiation
decreases as the particle size increases.
The limited outlet depth of the characteristic radiation makes it necessary that the distribution of elements
in the sample is homogeneous and
representative for the whole sample amount. Reliable and meaningful
analytical results can only be obtained
if these requirements are fulfilled.
The Vibratory Disc Mill RS 200
offers perfect sample preparation
for XRF analysis. It is particularly
suitable for the rapid reduction in
size of mineral substances such as
cement. The RS 200 can pulverize
a sample with a feed size of 15 mm
to a fineness <60 µm in only a few
seconds. During sample preparation
care must be taken that the grinding
tools are made of a material that is
neutral-to-analysis with respect to
the elements to be analyzed, as
abrasion can always occur during the
grinding process. With the RS 200
you can choose between 5 different
grinding set materials. This ensures
processing of the sample without
contamination.
In order to be able to press a stable
tablet it is often necessary to add a
binding agent to the sample before
the grinding process. The sample
can then be pelletized in a Pellet
Press such as the PP 40.
The “small” solution for XRF
For preparing small amounts of sample for XRF
we recommend the use of our Mixer Mill MM 301,
in which 2 samples can be ground at the same
time. It can achieve final finenesses down to
5 µm without any problems. After the grinding
process the sample is placed in a special polystyrene mixing jar together with a binding agent
and then mixed in the MM 301. The homogenized
material can now be pelletized in the Pellet Press
PP 25 to produce 32 or 40 mm tablets for analysis.

Fluid Bed Dryer.
Fluid Bed Dryer TG 200
Quick and gentle drying
The new Fluid Bed Dryer TG 200 is designed for universal use in quality control,
sample preparation and R&D. It permits
the gentle drying of bulk goods
without localized overheating.
The powerful fan ensures optimal air
throughput so that the products to be
dried are loosened up and thoroughly
mixed. The interval operation achieves
still better mixing of the fluidized bed.
The maximum temperature of 150 °C
is a considerable improvement compared with its predecessor. In comparison to conventional drying ovens,
the fluidized bed drying of the TG 200
results in a notable increase in performance. At idle speed the fan produces
3
an air flow rate of up to 185 m /h.
This results in drying times that can
be short as 5 minutes depending on
the amount and moisture content of
the material. This represents a considerable saving in time and is also
benefical for the product, which is
exposed to less thermal stress.
Temperature, drying time and air flow
can be set digitally and continuously
adjusted.
Accessories available include 6 liter
drying containers made of glass or
stainless steel. If small amounts of
different materials have to be dried
frequently and cross-contamination
has to be avoided then the use of the
0.3 liter drying container is recommended; the insert is equipped with
3 of these complete with filter bag.

The improved drying capacitiy of the TG 200 results in a
considerable saving in time compared with its predecessor.
TG 200 Technology
Drying in the TG 200 makes use of the fluidized bed
process. Ambient air is drawn in through a filter. A
blower moves the air across the heating elements,
and ultimately forces it through the perforated plate
and into the detachable drying container. The solid
particles are blown upwards and dispersed and
thus kept separate from one another. Thus their
sticking together is avoided - an annoying problem
in other processes. The warm air stream extracts
moisture from the particles and then exits through
the filter bag in the cover of the drying container.

The CCD cameras in the new CAMSIZER now work with a 100% higher

Extremely short exposure times allow for pin sharp images. The new
range from 30 µm to 30 mm. Thanks to newly developed fitting algorithms, the measuring results are perfectly compatible to those of
sieve analysis.
Measuring principle
The CAMSIZER uses the digital image
processing measurement principle.
A vibratory feeder transports the
sample to the measurement field,
where the particles fall between an
extended light source and two CCD
cameras. The projected particle
shadows are recorded at more than
60 images per second and analyzed.
Each single particle in the bulk goods
flow is recorded and evaluated.
A new type of LED-stroboscope
light source produces pin sharp
images and allows distortion-free
page 10 the sample
determination of the projection areas
due to extremely short exposure times.
The sharp contrast makes details
of the surface characteristics of
the particles visible, almost as under
a microscope. The frequency of the
light flashes is so high that the stroboscopic flickering is not visible to
the naked eye.
The unique and patented 2-camera
system ensures an excellent depth
of focus and therefore achieves
the highest precision throughout
the whole measuring range. The
zoom camera provides the highest
resolution right down to the micron
range. The basic camera also records
larger particles and ensures that the
results have a high degree of statistical certainty. This guarantees the
outstanding reproducibility of the
CAMSIZER measuring results, even
when only comparatively small
sample amounts are available.
The results are saved in at least
1,000 size classes.

Measurement
The CAMSIZER software is clearly structured and process-oriented, the operation is simple and intuitive. All control and evaluation functions are available in
a single program. The measuring parameters are stored in measuring tasks,
so that comparable sample material can always be measured under the same
conditions. A wizard function helps to create these measuring tasks, so that
the selection of transport speed, camera and evaluation settings can be carried
out quickly and reliably. Various password-protected user levels enable advanced
users to configure the software themselves for routine operation. In this way
the CAMSIZER can also be operated by untrained personnel, without settings
being altered or lost. The measuring data can be saved and managed locally on
a PC as well as automatically in a network. With the functions “Trend Analysis”
and “Daily Report” alterations in the sample quality can be recognized and
quantified.

The CAMSIZER is CE-tested and complies with the
relevant guidelines and standards such as the FDA
regulation 21 CFR Part 11.
The new CAMSIZER software
also offers:
■ additional shape parameters
(e.g. surface analysis)
■ improved sieve adaptation, also
for multimodal distributions
■ several language versions
(German, English and others)
With the CAMSIZER it is possible to
determine the mixing ratio of two
components if these lie in the same
particle size range but have different
shapes. The example shown here is
a mixture of ion exchanger granules
and active charcoal, as used in water
filters among other things. The graph
shows that the two components have
clearly different shapes. With the
CAMSIZER it is possible to determine
the mixing ratio of these two components quickly and easily without any
problems.
