Modular Processing Technology
With its modular design, Gneuss Processing Technology combines the individu-
al Gneuss product elements for economic, high quality and high performance
production processes in the most diverse areas of plastics processing and their
manufacture.
MRS Extrusion Concept
The patented MRS Multi Rotation System offers completely new possibilities with
regard to the efficient degassing and extrusion of polymer melts. Additionally,
this system also offers excellent dispersion performance for the introduction of
gases and / or all forms of additives.
Rotary Filtration Systems
The patented Gneuss Rotary Filtration Systems enable fully automatic, process and
pressure constant filtration. The main characteristic of these Filtration Systems is the
Rotary Disk with its ring of screen cavities, rotating between two solid steel blocks.
Online Viscometer VIS
The Online Viscometer VIS provides reliable and accurate measurement of the
melt viscosity according to DIN 53014 guidelines. The unit operates without
material loss. It is simple to operate and cleaning of the capillary can be carried
out without any influence on the production process.
Vacuum Technology
The standard vacuum systems operate with a simple and robust water ring pump
with a standard vacuum level of down to 25 mbar. Systems for vacuum levels
down to 1 mbar can be supplied. The gas and particle separation is simple and
environmentally friendly.
Control System Technology
The use of patented measurement and control technology permits Gneuss to
simplify extrusion processes while at the same time increasing their reliability.
Application Case Examples
The performance offered by Gneuss Processing Technology is already well pro-
ven. These advantages are described by means of case examples from PET sheet,
bottle-to-bottle-recycling and fiber production as well as PE and PP recycling.

6 | MRS Extruder
DesignMrs eXtruder
The polymer melt is delivered into a large single
screw drum. The drum contains 8 small extruder
barrels, parallel to the main screw axis. Installed
in these small extruder barrels are the „satellite“
screws, which are driven by a ring gear in the main
barrel.
The satellite screws rotate in the opposite direction
to the main screw while they rotate around the
screw axis.
This disproportionately increases the surface area
exchange of the polymer melt. The extruder barrels
which are cut into the drum of the Multi Rotation
System are approximately 30% open to ensure the
optimum melt transfer into the barrels, so that the
devolatilization can take place without restrictions.
Further, precise control of the melt temperature is
possible as the temperatures of all the surfaces in
contact with the melt can be controlled accurately.

High Performance DevolatilizationMrs eXtruder
Thanks to its Multi Rotation Element, the
surface area – and the surface area exchange
rate – available for devolatilization are far
greater than in other extrusion systems
available on the market. The surface area of
the steel parts in contact with the melt is
exchanged at a rate of more than 25 times
greater than with a co-rotating twin screw
extruder. Due to the opposite rotation
direction and high speed of the satellite
screws, the polymer surface area is increased
by a factor of 100 compared to a single screw
extruder and a factor of 40 compared to a twin
screw extruder. The devolatilizing
performance of the MRS extruder
can be summarized as follows:

Overview of Gneuss Melt Filtration Systems
The lines below the Rotary Disks show the pressure curves in operation.

Filtration Systems | 11
The control system reacts to this pressure
increase and makes the filter disk index by 1-2
angular degrees. Thus, contaminated screen area
is continuously moved out of the melt channel
and clean screen area is moved into the melt
channel without changing the active filter area.
Due to this mode of operation, the filtration system
operates process- and pressure-constantly. The
variation of the pressure differential across the filter
( p) amounts to max. 2 bar.
The Rotary Filtration System explainedExample: RSFgenius
• A high pressure, sequential back flushing
systems cleans the contaminated screen
packs before they re-enter the melt channel.
• Polymer from the clean (filtered) side of the
screen changer is siphoned into a hydraulically
operated piston that shot with 30 to 80 bar
across the filter element (in the reverse direction).
• Only one small segment (approx. 1 % of
the filtration area) is cleaned at a time,
with a defined, high pressure impulse.
The self-cleaning (backflushing) system
Rotary Filtration Systems consist of three main
parts – an inlet block, an outlet block and a filter
disk rotating between them. The system is sealed
by a metal to metal sealing with very narrow gaps
as well as very hard and flat surfaces. It is guaran-
teed that all components in contact with melt are
not in contact with the environment (e. g. oxygen).
The screen elements are located in a ring pattern
on the filter disk, moving through the melt
channel. When melt flows through the screen,
hard particles get caught and the differential
pressure increases slightly.

The Gneuss Online Viscometer offers precise
measurements of those polymer properties
which have a decisive influence on the product
quality. The measured viscosity is in direct
relationship to the physical properties of the
material such as tensile strength and impact
resistance. Quality assurance can be improved
through the monitoring and recording of this
data.
By means of a high precision metering gear
pump, a small part of the polymer melt is
separated from the main melt channel. This is
pumped through a precisely manufactured slot
capillary.

VIS | 13
Pressure Transducer
Melt Pressure transducers used in plastics proces-
sing operate using the principle of a medium to
transfer the pressure from the hot environment to
the sensitive measurement electronics. A dia-
phragm in contact with the polymer melt deforms
due to the melt pressure. This deformation forces
a liquid in a capillary to transfer the pressure to a
second diaphragm, equipped with a Wheatstone
bridge sensor, which translates deformation into
an electric signal. The liquid medium in the capil-
lary is typically mercury; however the use of these
sensors in the manufacture of food packaging is
not permitted. The Gneuss sensors on the other
Melt Temperature Sensor
The Gneuss TF range of Melt Temperature Sen-
sors is ideal for the exact measurement of highly
sensitive media. The ceramic insulation guarantees
a direct measurement of the melt temperature at
all times, independent of the temperature of the
surrounding steel components, such as a flange
barrel or die.

replacement of mercury with an environmentally
safe substitute medium, melt pressure measu-
rements with
the required
accuracy can
be obtained
in all applica-
tions, including
in the area of
food contact
packaging
materials.
Both the melt temperature and the melt pressure
(measurement in 2 positions) are monitored. Based
on internal calculations, the Online Viscometer
calculates a value for the representative shear rate
and the corresponding representative viscosity.
The depth of the capillary slot is specified accor-
ding to the material properties within a range of
0.5 to 2.0 mm. The unit is supplied complete with
a precision metering pump, its drive, melt pressu-
re transducers, melt temperature sensor, heater
elements and the complete evaluation and control
software and hardware package. The control
elements can of course also be integrated into a
process control system.

14 | Vacuum
VacuuM technology
The vacuum system is the key to the whole devola-
tilization process. Not only is it important to create
a vacuum – the separation of solid particles from
the volatiles which are extracted from the material
presents a particular challenge. Many extruders
require an absolute pressure of < 5 mbar, using dry
vane vacuum pumps.
During the devolatilization of polymers, it is ine-
vitable that monomers, oligomers and other solid
particles or sublimates are sucked out. If these
enter the pump, they will drastically reduce its ope-
rating life and for this reason, separating systems
are needed which under tough industrial operating
conditions are extremely maintenance intensive.
Advantages of the MRS vacuum system:
• Handles liquids, vapor and solid particles
• Isothermal compression
(no contamination during condensation)
• Oil free compression
(no contamination during condensation)
• Simple design with water ring pump and
belt filter
• Robust and not sensitive to blocking of
suction and pressure pipes
• Standard vacuum level of 25 mbar
(Water ring pump technology),
special solutions for 1mbar
Thanks to its extremely high surface area exchange
rate, the MRS extruder can in most cases provide
excellent devolatilization with a vacuum of only
30 mbar. This permits the use of much simpler
and less sensitive water ring pumps which create a
vacuum using a rotating impeller, mounted eccen-
trically to the liquid ring.
The liquid in circulation can be passed over a belt
filter under atmospheric conditions. In this way,
the maintenance of the system can be reduced to
an absolute minimum.
The circulating fluid is heated through the process.
In order to avoid an increase in the steam pressure,
the liquid is pumped through a heat exchanger
where it is kept at a steady temperature of around
10°C. The intelligent design permits simple
cleaning of the heat exchanger while the system is
operating.

The control system is a key element in any extrusion line. Today, a control system is expected to
link all the line components together in an efficient and operator friendly central system.
16 | Control
control technologyThe MRS control system
Gneuss developed the MRS control system in order
to take effective advantage of all the measurement
data and set points provided. The various line com-
ponents are linked together by the control system
to a central operating system. Changes in the pro-
cess are identified immediately and if necessary, can
be corrected. The production data is stored for later
diagnosis or documentation and is processed by
the control system to trends with history function.
Most extruder operators will find that working with
the lean, user- friendly operating system is intuitive
with little need for explanation. Only a few clicks
on the touchscreen monitor are necessary to get
the line into production.
The standard control system hard- and software
supports the following line components:
• Heater controls for the complete line
• Extruder drive
• Melt pump drive
• All melt pressure measurements
• Vacuum system
• Online Viscometer
• Rotary Melt Filtration System
• Dosing
• Pelletizer

Control | 17
The individual integration of the interfaces and
Bus systems permits the communication of control
systems from various suppliers. The data transfer
within the MRS control system is divided into 3
Bus systems.
The measurements on the extruder are gathered
centrally and are transferred to the PLC via CanBus
or Profibus. In this way, only two data cables
are necessary, instead of the conventional cable
bundle.
This technology keeps the level of installation and
maintenance to a minimum. The communication
within the control cabinet is handled by the Profi-
bus DP protocol.
The MRS can be supplied with a telemaintenance
facility via the internet. The telemaintenance client
is integrated in the customer network and when
required, connects with the Gneuss server. In this
way, the security of the customer’s network is
protected.

18 | Sheet
sheet ManufactureApplication case example
MRS extruders are in use throughout the world
on PET thermoforming sheet lines. A typical case
example is a line for the processing of PET with the
MRS 130 at a throughput rate of 1,000 kg/h. The
main application of this line is the manufacture of
sheet for subsequent thermoforming to containers
for packaging fruit. The MRS extruder plasticizes
and devolatizes the material, the RSFgenius filters
Gneuss´ Processing Technology is already well proven worldwide. The energy intensive and
therefore costly step of pre-drying and crystallization of the material can be eliminated, when
manufacturing PET sheet for thermoforming with the MRS extruder.
the material (at a fineness of 56 to 75 microns).
The Online Viscometer VIS measures the viscosity
immediately upstream of the die and controls the
vacuum pump at the devolatilizing section of the
extruder in order to maintain the viscosity within
a narrow range. The quality of the sheet and also
the sheet thickness are maintained at a consistent
level.
An MRS 110 extruder was supplied for a PET ther-
moforming sheet line for packaging containers. It
replaced a single screw extruder with pre-drying,
saving 25 % of the footprint and 15 to 25 % of
the energy due to the MRS not needing pre-dried
or crystallized material. Additional benefits are the
increased flexibility with regard to the raw material
used, color changes etc. thanks to the elimination
of pre-drying and crystallization.
On this line, a mix of reground skeletal waste, bot-
tle flake and virgin material is processed, with no
pre-drying and with simple vacuum technology,
without gas purification and without the corres-
ponding high maintenance requirements.
Analysis by the Fraunhofer Institute have shown
that the MRS concept not only does an excellent
job of devolatilizing with regard to extracting the
moisture from PET, but it also removes harmful
volatiles efficiently, for example from post
consumer PET bottle flakes.
The MRS extrusion concept is therefore able to
process 100 % PET bottle flakes for products with
food contact.
-
Bottle to Bottle recyclingApplication case example
The MRS extruder processes PET bottle flake
without drying or other pre-treatment directly into
pellet or sheet. The polymer surface is rapidly and
intensively renewed in the Multi Rotation System
in the extruder, providing excellent decontamina-
tion even with a moderate vacuum of 25 to 40
mbar and with a limited, controlled IV drop. The
material is processed gently so that the final pro-
duct has a high quality with regard to the yellow
value, for example.
Thanks to its excellent and unique performance characteristics, the MRS also lends itself to the
processing of PET bottle flakes to bottle grade chip.
Early 2010 a “Letter of Non Objection“ (LNO) was
issued by the American Food and Drug Administ-
ration (FDA) for Gneuss‘ bottle to bottle recycling
process. The FDA LNO is for up to 100 % recycled
material and means that the entire chip manufactu-
red on this process can be used for food containers
of any kind in the USA, regardless as to whether
the containers are for cold or hot fill applications.
The bottle to bottle recycling process consists of
the MRS extruder, a fully automatic Rotary Filtration
System and a short solid state polymerization (SSP)
in order to lift the IV to 0.8 or higher.

20 | Fiber
fiBer ManufactureApplication case example
Many synthetic fiber manufacturers throughout
the world have already chosen the MRS extrusion
system from Gneuss.
One of these is a Brazilian company which uses two
MRS extruders to produce bicomponent staple fiber
with two extruders: an MRS 130 for the main com-
ponent with a throughput rate of up to 900 kg/h
and an MRS 110 for the second component with
a throughput rate of up to 500 kg/h. Both are fed
with the same undried post-consumer PET bottle
flake material and extrude the PET with different
IVs on each extruder.
Silon s.r.o. is another leading Eastern European
manufacturer of staple fibres. Silon also operates an
MRS extruder: an MRS 130 with vacuum, melt filter
RSFgenius 200 and gear pump. The MRS 130 re-
placed a conventional single screw extruder, dispen-
sing with pre-drying of the material. It was possible to
increase the production capacity by 30 %. Thanks to
the Multi Rotation System MRS extruder pre-drying or
crystalliztation can be eleminated and flakes with a re-
sidual moisture level of as high as 2 % are processed.
For fiber manufacturing the unique multiple screw extruder can supply a high quality melt from
quality reclaim. 100 % recycled content can be used, resources are saved, energy use is mini-
mized and raw material costs are reduced.
The Belarussian company, Mogilevkhimvolokno is
another Eastern European manufacturer of staple
fiber and also decided to use the MRS extruder.
Mogilevkhimvolokno manufactures a wide range of
staple fiber including bicomponent fiber with a low
melting point and an IV value of 0,55 to industrial
quality fiber with an IV of up to 0,9.
When manufacturing these fibers, production waste
of all types is created, some including spin finishing
oils. In order to recycle this wide range of waste, an
MRS 90 extruder from Gneuss was installed which
is used to devolatilize the undried material and to
glycolyse the material to a uniform IV before it is
filtered and pumped into the final reactor (finisher)
where polycondensation takes place. This process
permits recycling of practically all the production
waste and the quality of the fiber manufactured with
this recycled content is practically no different to that
of fiber manufactured using virgin material.

Polyester straPPing taPes Application case example
The MRS Extrusion technology was installed in a
line for strapping tape from the Italian manufac-
turer SIMA GROUP SRL., processing 100 % of non
dried post consumer bottle flakes. There is only a
small amount of PE based additive used for impact
modifying (splicing inhibitor) of 1.2%, which is
normal to be used in strapping applications.
The throughput of the line is around 350 to 400
kg/h.
By avoiding the need for crystallizing and drying and with the use of a simple vacuum system,
the MRS extruder permits energy savings of approx. 20 % and thanks to its compact design
requires 12 % less space in the factory.
The die head contains 3 gear pumps producing 6
tapes with a dimension of 12.5 mm wide x 0.65
mm to 0.8 mm thick. Stretching ratio is around 1
to 8 and the haul off speed is up to 120 m/min.
Strapping tape / PE/PP recycling | 21
Pe/PP recycling
The MRS devolatilization concept can not only remove water vapor from the melt efficiently; it is
also an efficient system for the removal of harmful or unwanted volatiles from the polymer melt.
Heavily contaminated materials can therefore be reprocessed with a drastic reduction in odor.
A manufacturer of film for packaging processes
scrap printed LDPE blown film to carrier bags.
As this film had been previously used for packing
fish, it had assumed an unpleasant odor.
It was previously necessary to use a mixture of
6 % washed „fish“ film waste with 94 % virgin
material to reduce the odor problem. Thanks
to the MRS extruder it is possible to add 40%
recycled material instead of the previous 6%.
The efficiency of the MRS technology was also
proven in the manufacture of PP recycled com-
pounds for the automotive industry. This work was
carried out together with the Fraunhofer Institute
in Pfinztal (Germany) which proved the results
using themal desorption analysis. A large propor-
tion of the volatiles are extracted from the polymer.
The residual volatile level is 22 % at 50 mbar and
only 10 % at 20 mbar.
Application case example
-
In many polymerization processes, it is necessary
to remove residual monomers after polymerizati-
on. In most cases, in a complex and cost intensive
process, the residual monomer content of approxi-
mately 10 to 12 % is washed out with hot, distilled
water and returned to the process (hot water
extraction).
This extraction process can be greatly simplified
with the help of the MRS technology.
The monomers can be extracted in the melt phase
(before chip cutting) and are extracted in a form
that permits them to be returned directly to the
process.

• Extraction of residual water and monomer from polycarbonate (PC)
• Monomer extraction and removal of monostyrene from acryl nitrile butadien copolymer
(ABS) or styrene acryl nitrile copolymer (SAN)
• Reduction of effluvia (VOC/fog) in final product, for example from vehicle interior
components manufactured from polyacetal (POM), polypropylene (PP), acryl nitrile
butadien copolymer (ABS)
• The introduction of chemical or physical blowing agents and/or other components in gas
form for the manufacture of foamed products from polystyrene (PS), polyethylene (PE),
polyester (PET) or polypropylene (PP)
devolatilization of Pa
The inclusion and dispersion of additives in poly-
mers is normally carried out in the polymer melt
prior to the mixing process. With the MRS Disper-
sion Technology, the approach is quite different.
The introduction of the additives does not take
place under pressure and with a shear gap, but by
a constant and drastic change of flow direction in
a pressure-free environment.
Mrs dispersion technology
In this way, major differences in speed are created
between the particles to be mixed and the mo-
lecule chains. This creates an extremely efficient
mixing process which is extremely gentle to both
the polymer melt and the additive.
The MRS system also provides excellent results in
the dispersion of extremely small (nano) particles
and in the homogenization of polymers (alloying)
with different viscosities.
