Airtube systems
Air tube systems are commonly used in
basic industries for the transport of powder- and metal
samples. The samples are taken from the process in the plant and
send to the laboratory for preparation and analysis.
Pressurized air drives the transport carriers through the
transport tubes. HERZOG uses steel tubing with a smooth inner
surface, and carriers made of steel or a synthetic material
that do not require a leather end cap seal. The transportation
speed is a direct function of carrier back pressure and change
in vertical elevation |
 |
 |
Airtube components
In simple systems the sample is
places into the carrier and the introduction of the carrier into
the system is manually.
HERZOG supplies manually operated sending- and receiving
stations of a robust design for
industrial use.
|
 |
The tubes from
two or three separate sending stations n the plant can be joined
by means of tube diverters to one tube and one receiving station
in the laboratory. The diverters are gear motor driven
integrated in a closed steel
housing and can be installed in areas of difficult environmental
conditions.
|
 |
In more complex automated systems samples are taken
automatically from the process stream. HERZOG supplies different
types of in-line samplers for various applications. |
 |
The output of
the samplers is connected to an automatic sending station.
These station are available with integrated mixers, sample
splitters
and dosing devices and can have a build-in compressor for the
control
air to be independent from the plant air. Optional integrated
heaters allow
for installation in areas of low temperatures.
|
 |
Especially
designed for automated steel plant and cement plant
laboratories and robot laboratories receiving stations with
multiple incoming lines are available. The samples are
automatically
unloaded from the carriers and transported to the preparation
machines

HP-MA
Grinding Mill
Fully automatic sample preparation
for X-ray fluorescent
analysis with all its advantages is made by HERZOG
pulverizing mills and pellet presses in modular design.
The automatic method of operation with program-controlled
grinding and pressing processes achieves a clear improvement
reproducibility in sample preparation and thus better analysis results.
HERZOG HP-M series pulverizing mills
are suitable for grinding minerals
such as ferro-alloys and organic materials. The high RPM of the drive
motor guarantee short grinding processes even with hard materials and
the robust construction with, for example, dual bearing support for the
eccentric shaft ensure long service lives.
Additional special features of the
HERZOG HP-M series pulverizing
mills are automatic emptying of the grinding vessel and availability
of the sample material at the discharge point. Automatic cleaning of
the grinding vessel ensures continuous operation even with consecutive
preparation of different materials. Cleaning is carried out
pneumatically
of by wet-grinding followed by drying. Wet-grinding has the particular
advantage that even the smallest grinding residues are removed.

HP-PA Pellet press
HERZOG HP-P series pellet presses are the basis for the manufacture of
stable pressed pellets. They offer the properties which are crucial for
achieving the desired uniformity and density of each individual pressed
pellet. The design of the pellet presses ensures a high degree or
reproducibility in sample preparation. The design of the equipment and
variability of the pressing parameters ensure uniform optimal quality of
pressed pellets from all ground materials.
All the parameters which are important for the pellet pressing process
such as total pressing force, incremental increase of the pressing force
and pressure holding time can be preset.
They are controlled directly, reliably and continuously via a program.
Errors caused by incorrect handling or adjustment are now a thing of the
past. Access to the program parameters is only possible using a
password.
In the standard version of the press the counterpressure plate of the
die is cleaned with a brush which rotates in alternate directions. As an
option a Mylar film device effectively prevents material particles from
becoming fixed to the counterpessure plate.

HSM 100 Grinding
Mill (right) Beside HTP 40 Pellet Press (left)
HERZOG vibration mills offer the full benefits of program – controlled
grinding processes for the preparation of samples for x – ray
fluorescence analysis. Control by programmable controller results in a
substantial improvement in the reproducibility of sample preparation and
consequently optimum analysis results.
HERZOG HSM 100 vibration grinding mills are suitable for the grinding of
minerals, slags, ferro alloys, organic substances and other materials.
The high speed of the drive motor enables even hard material to be
ground with short process times. The robust design with twin eccentric
disk bearings enable the grinding mills to achieve a long service life
with a minimum of maintenance.
The grinding processes on the HERZOG vibration mills are controlled
reliably by a PLC program. This eliminates incorrect handling or
settings as sources of errors. The parameters can be accessed only
through a password.
HERZOG pellet presses offer the full benefits of program – controlled
pressing processes for the preparation of samples for x – ray
fluorescence analyses. Control by programmable controller results in a
substantial improvement in the reproducibility of sample preparation,
and consequently optimum analysis results.
HERZOG hydraulic HTP 40 and HTP 60 pellet presses for preparation of
samples for x – ray fluorescence analysis are an essential part of the
manufacturing process for stable pressed pellets. They possess all the
characteristics required to guarantee the homogeneity and stability of
each individual pellet.
With the high press forces of 400 kN in the case of the HTP 40 and up to
600 kN with the HTP 60, a high compression is achieved, even with large
sample diameters.
The pressing processes performed by HERZOG pellet presses are controlled
reliably by a PLC program. The result is a substantial improvement in
the reproducibility of sample preparation , and consequently improved
analysis results.
Parameters of relevance to the pressing process, such as press pressure,
rate of compression and pressure holding time, can be varied. They are
controlled reliably through a program.
The build-up and release of pressure during pressing are controlled such
that inner stress within the sample are reduced. This ensures perfect
pressing even of materials which in the past have proved difficult to
press.
The programmable controller eliminates improper handling or incorrect
settings as a source of errors. The parameters can be accessed only
through a password.
