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.

6 | MRS

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 ex-

change of the polymer melt. The extruder barrels

which are cut into the drum of the multi rotation

system are approximately 30% open (see illustra-

tions 4 and 5) to ensure the optimum melt transfer

into the barrels, so that the evacuation 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.

Performance comparisonmrs devolatilization technology

The specific energy requirement of the MRS system

is typically 15 to 25 % less than for conventional

technologies as it needs neither pre-drying nor

powerful vacuum systems. Compared with the single

screw extruder when processing PET, pre-treatment

of the material in the form of drying and crystallizing

can be avoided thereby saving operating and main-

tenance costs along with energy savings. The MRS

Energy efficient

also has a lower energy consumption when compa-

red with corotating twin screw extruders. In the case

of PET processing, there are additional savings with

the MRS as this system requires neither a powerful

vacuum system ( < 5 mbar) nor partial pre-drying of

the material. Furthermore, the MRS delivers suffici-

ent pressure that in most cases, a melt pump is not

necessary to boost the pressure.

Thanks to the multi rotation elements, a melt

surface area is made available which is far greater

than that of conventional extruders.

For example: the MRS system creates a melt surface

area which is 25 times greater compared with a

corotating twin screw extruder.

10 | Filtration Systems

Filtration is the key to ensuring quality and cost efficiency not only on recycling applications.

Rotary Filtration Systems from Gneuss represent the ideal solution, thanks to their fully conti-

nuous and pressure-constant operation.

• Fully-automatic mode of operation

(with integrated self-cleaning)

• Constant melt pressure, temperature, viscosity

and throughput

• Guaranteed melt purity and quality, short dwell

time of the melt

• Simple and safe screen changes, low filtration

costs

• Compact size and minimal installation effort

The advantages of Rotary Filtration Systems

Overview of Gneuss Melt Filtration Systems

The lines below the filter elements and / or the Rotary Disks show the

pressure behavior during screen or filter element changes.

pressure increases slightly. 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.

Filtration Systems | 11

The Rotary Filtration System explainedexample: RSFgenius

• A high pressure, sequential and segmental 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 bled into a hydraulically opera-

ted shooting pot and is injected with 30 to 80

bar across the filter element in the reverse direc-

tion to normal.

• Only one small segment (approx.

1 % of the filtration area) is clea-

ned 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 pat-

tern on the filter disk, moving through the melt

channel. When melt flows through the screen,

hard particles get caught and the differential

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.

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:

• Resistant to liquids / vapors and solid particles

• Isothermic compression (no contamination

during vapor condensation)

• Oil free compression (no contamination during

vapor condensation)

• Simple design with corrosion resistant materials

• Resistant to blocking of the suction and pressu-

re lines (the pump can not run dry).

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 an 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 19“ 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

• Melt Filtration System

• Dosing feeder

• Pelletizing

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.

Gneuss Solution:

Safety System EPM

Melt pressure overload protection for extrusion lines

Throughout the world, the requirements on

plastics and rubber machines with regard to safety

protection against overpressure are increasing.

With the Gneuss safety system EPM, the use of

stretch bolts, fail safe components, rupture discs or

movement sensors can be avoided.

Extruders, melt pumps or components which are

under pressure can be protected against excess

pressure by the EPM safety system, with a duplica-

ted and monitored pressure measurement.

The safety-relevant components of the monitoring

system conform to EN ISO 13849 -1, with a perfor-

mance level of “c”.

18 | Sheet

sheet manufactureApplication case example

MRS extruders are in use throughout the world on

PET thermoforming sheet applications. 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 manu-

facture of sheet for subsequent thermoforming to

containers for packaging fruit. The MRS extruder

plasticizes and devolatizes the material, the RSFge-

Gneuss´ Processing Technology is already well proven worldwide.

In the manufacture of PET sheet for thermoforming with the MRS extruder, the energy intensive

and therefore costly step of pre-drying and crystallization of the material can be eliminated.

nius filters the material (at a fineness of 56 to 75

microns). The Online Viscometer VIS measures the

viscosity immediately upstream of the die and con-

trols the vacuum pump at the devolatilizing section

of the extruder in order to maintain the viscosity

within a narrow range. In this way, not only can the

quality of the sheet but also the sheet thickness be

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,

bottle flake and virgin material is processed, with

no pre-drying and with extremely simple vacuum

technology, without gas purification and without

the corresponding 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 also removes harmful volati-

les 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, fully automatic Rotary Filtration

System and a short solid state polymerization (SSP)

in order to lift the IV to 0.8 or higher.

20 | Strapping tape

Polyester straPPing taPes Application case example

An MRS 90 extruder, together with a fully automa-

tic Rotary Filtration System and Online Viscometer

was installed in a line for strapping tape from the

Italian manufacturer SIMA GROUP SRL.

The line is processing 100 % of non dried post con-

sumer 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 far 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.

Compared to conventional systems (single screw

with crystallization and pre–drying) it was establis-

hed that the required space for the installation with

the MRS system is much smaller. This space saving

is around 12%. By using the MRS technology it is

no longer necessary to use conventional drying and

crystallization.

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 was able to

obtain large quantities of printed LDPE blown film

from a big fishery. As this film had been previ-

ously used for packing fish, it had assumed an

extremely unpleasant odor.

The film manufacturer grinds the film, washes it

and processes it together with virgin material to

carrier bags which are sold to supermarkets.

Thanks to the unpleasant odor due to the contact

with fish, it was previously necessary to use a

mixture of 6 % washed „fish“ film waste with

94 % virgin material in order to reduce the odor

problem to the point that the bags could be sold.

A practical test showed that it is possible to add

40 % recycled material in the form of pellets

manufactured on the MRS extruder without any

noticeable difference to the bags manufactured

previously.

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.

The samples were heated and the gas emitted

was analyzed using a mass spectroscopy analysis

(thermal desorption according to VDA 278). The

influence of the absolute pressure (vacuum) during

extrusion was evaluated.

The graph below clearly shows the minimization

of the volatile components from the pellets. With

application of vacuum in the melt phase, a large

proportion of the unwanted volatiles could be

removed from the material.

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.

devolatilization of Pa (nylon)

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.
