The MRS extruder is based on the conventional single screw extruder, but is equipped with a multiple screw section, for optimum devolatilisation.

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 exchange of the polymer melt.

So that the volatiles can be freely evacuated, the MRS extruder is equipped with a large opening for venting (exposing the full length of the satellite screws) which is completely under vacuum. This provides excellent and unrestricted access to the polymer melt, the surface of which is constantly replaced at an extremely high rate by the action of the satellite screws in the multiple screw section.

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.

Thanks to its Multi Rotation Section, the surface area – and the surface area exchange rate – available for devolatiliz-ation are far greater in the MRS 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.

• Devolatilization of oils, odors and other volatiles

Efficient distributive mixing in the multi rotation section:

• Highest quality of melt and product

• Excellent product properties

10 Vacuum Technology

The vacuum system is the key to the whole devolatilization 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 a vacuum of < 5 mbar, using dry vane vacuum pumps. During the devolatilization of polymers, it is inevitable that monomers, oligomers and other solid particles or sublimates are sucked out. If these enter the pump, they will drastically reduce its operating life and for this reason, separating systems are needed which under tough industrial operating conditions are extremely maintenance intensive.

Thanks to its extremely high surface area exchange rate, the MRS extruder can in most cases provide excellent devola-tilization with a vacuum of only 25 - 30 mbar. This permits the use of much simpler and less sensitive water ring pumps which create a vacuum using a rotating impeller, mounted eccentrically 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 and a weakening of the vacuum, 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.

Whilst the MRS extruder operates on standard applications with its low maintenance 25 mbar liquid ring vacuum system, special effects can be achieved using its intensive surface area exchange in combination with deeper vacuums (e.g. 0,5 - 2 mbar). Gneuss has also standard solutions available for such applications.

• Handles liquids, vapor and solid particles

• Isothermic compression (no contamination during condensation)

• Oil free compression (no contamination during condensation)

• Simple design with water ring pump and belt filter

• Robust and insensitive to blocking of suction and pressure pipes

12 Control Technology

Control TechnologyThe MRS control system

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.

Gneuss developed the MRS control system in order to take effective advantage of all the measurement data and set points provided. The various line components are linked together by the control system to a central operating system. Changes in the process 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 and archived.

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 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 by means of the Profibus DP protocol.


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

• Designed according to EN1114 -1

• Two redundant sensors 4…20 mA, to which the same pressure is applied

• Two safety-related analogue inputs

• Self-monitoring

• Two safety-related relay outputs, the emergency stop of the unit

• 4...20 mA signal for pressure evaluation

• Optional Bus interface

Protection against pressure overload for extrusion lines

Throughout the world, the requirements on plastics processing and rubber machinery with regard to safety protection against pressure overload are increasing. With 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 duplicated and monitored pressure measurement. The safety-relevant components of the monitoring system conform to EN ISO 13849 -1, with a performance level of “c”.

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.

14 Rotary Filtration Systems

Filtration is the key to ensuring quality and cost efficiency not only in recycling appli-cations. The Rotary Filtration Systems and screen changers from Gneuss represent the ideal solution, thanks to their continuous and pressure-constant operation.

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 guaranteed that all components in contact with melt are never in contact with the environment (e. g. oxygen).

The screen elements are located in a ring pattern on the filter disc and move through the melt channel. When melt flows through the screen, hard particles get caught and the differential pressure increases slightly.

The control system reacts to this pressure increase and indexes the filter disk by 1-2 angular degrees at a time. 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-constant. The variation of the pressure differential across the filter ( p) amounts to max. 2 bar.

The advantages of Rotary Filtration Systems

A high pressure, sequential back flushing system cleans the contaminated screen packs before they re-enter the melt channel.

Polymer from the clean (filtered) side of the screen changer is taken by a hydraulically operated piston and shot with 30 to 80 bar across the filter element (in the reverse direction).

Only one small segment (approx. 1 % of the filtra-tion area) is cleaned at a time, with a defined, high pressure impulse.

• Fully-automatic mode of operation (with integrated self-cleaning for RSFgenius and optional for SFXmagnus)

• 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

• Rheologically optimized flow channel

• Minimal backflushing losses with self-cleaning RSFgenius model

16 Viscosity measurement

The Gneuss Online Viscometer offers precise measu-rements of a polymer property, which has 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 in bypass through a precisely manufactured slot capillary before returning to the main material flow.

Both the melt temperature and the melt pressure (measurement in 2 positions) are monitored. Based on internal calculations, the Online Viscometer cal-culates a value for the representative shear rate and the corresponding viscosity.

The depth of the capillary slot is specified according to the material properties within a range of 0.5 to 2.0 mm. The unit is supplied complete with a precisi-on metering pump, its drive, melt pressure trans-ducers, 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.

Pressure Transducer

Melt Pressure transducers used in plastics processing operate using the principle of a medium to transfer the pressure from the hot environment to the sensi-tive measurement electronics.

A diaphragm 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 Wheat- stone bridge sensor, which translates deformation into an electric signal.

The liquid medium in the capillary is typically mercury; however the use of these sensors in the manufacture of food packaging is not permitted.

The Gneuss sensors are also offered with mercury-free liquid. Through the replacement of mercury with an environmentally safe substitute medium, melt pressure measurements with the required accuracy can be obtained, including in the area of food contact packaging materials.

Melt Temperature Sensor

The Gneuss TF range of Melt Temperature Sensors is ideal for the exact measurement of highly sensi-tive media.

The ceramic insulation guarantees a direct mea-surement of the melt temperature at all times, independent of the temperature of the surrounding steel components, such as a flange barrel or die.

Thermoforming Sheet Turnkey Solutions

Gneuss Sheet Extrusion Lines are flexible and can be operated with recycled material and / or virgin material. Sheet made from recycled material is suitable for food contact applications.

Sheet extrusion lines based around the Gneuss Processing Unit (GPU) are in operation worldwide in the manufacture of PET sheet for thermoforming. The applications range from monolayer sheet from 100 % post consumer bottle flake for food contact applications to liquid coated and laminated sheet.

Typical applications are throughput rates from 350 kg/h to 2.000 kg/h, sheet widths of up to 2.000 mm and sheet thick-nesses between 0,15 and 1,2 mm. In addition to PET bottle flake and virgin material (pellets) edge trim and skeletal waste regrind from PET, GAG and PET sheet with PE lamination are often added. Due to the especially gentle direct processing without pre-drying, crystallising or frictional heat, materials with widely different melting points can be processed directly.

• High transparency and gloss, low yellowness

• High toughness and impact resistance, low brittleness

• Very good thermoformability due to excellent molecular distribution

• Letter of Non Objection (LNO) from the FDA for up to 100 % recycled content, EFSA conformity for direct food contact for both monolayer and co-extruded sheet

• Processing of polymers with low melting points such as PETG and PE together with regrind from 2 ply sheet PET/PETG and laminated PET/PE sheet

• Quick material changes, high flexibility

• Major energy savings, low space requirements, simple maintenance

Bottle-to-Bottle-RecyclingTurnkey Solutions

Gneuss pelletising systems produce excellent quality pellets, which are thanks to the MRS extrusion process already suitable for processing to food contact products.

The MRS extruder processes undried PET bottle flake without any pre-treatment directly into pellets. The polymer melt is intensively and rapidly exchanged in the multiple screw section of the extruder. The huge surface area is exchanged at an unparalleled rate so that even with a moderate vacuum level of 25 to 40 mbar in the degassing section, contaminants are efficiently evaporated out of the melt. A letter of Non Objection (LNO) from the FDA underlines the decontamination effi-ciency. If, in order to boost the intrinsic viscosity (IV) a downstream solid state polymerisation system (SSP) is used, this can be specified far shorter than otherwise necessary as the extruder has already carried out the decontamination of the bottle flakes. The end product is of especially high quality with regard to transparency and yellowness.

• Devolatilization of oils, odors and other volatiles

• Letter of non Objection (LNO) from the FDA, EFSA confor-mity and local certification together with certification from major global brand owners for direct food contact

• Extraction of residual monomers

• Uniform, homogeneous pellets

• Devolatilization of oils, odours and other volatiles

• Stable IV even when processing materials with varying residual moisture levels

• Highest melt purity

• Fibre waste can be used to replace virgin material


Advantages of Gneuss Industrial Waste Recycling Lines

The Gneuss Industrial Waste Recycling System consists of a specially configured Gneuss Processing Unit together with the optional polyreactor „Jump“ for reprocessing and direct feeding with an extremely wide range of production waste.

Even fibre waste which is coated with spin finish oils and other contamination and with a high moisture level can be fed into the MRS extruder. The material is melted, devolatilised and decontaminated in the extruder. Volatile contamination such as water or spin finish oils are extracted. Subsequently, the polymer melt can be either pelletised, mixed (blended) in the melt phase with material from a production extruder, fed directly as melt to a spin beam (extrusion spinning) or fed as melt in side stream into the main polymerisation stream upstream of the finisher.

Industrial Waste Recycling Polyester Strapping TapeTurnkey Solutions

In spite of the avoidance of time and energy intensive drying and crystallisation of the PET bottle flake which is needed with conventional single and twin screw extruders, strapping tape made on the MRS extruder has equivalent properties in terms of tensile strength, stretch and splitting. Additionally, the highly efficient vacuum devolatilising system ensures high melt purity with a considerably lower monomer and oligomer content than with conventional technologies, so that the risk of strap breaks and weak points in the straps during production are greatly reduced.

With Gneuss PET strapping lines, polyester strapping tape with a high tensile strength can be manufactured from 100 % recycled material.

Application case example

The Gneuss extrusion systems for fibre manufacture process not only virgin material but also PET post consumer bottle flakes or production waste such as spin finish oil coated fibre waste and start up lumps to high quality fibres, without any pre-drying of the material.

Bicomponent (core / sheath etc.) staple fiber can for ex-ample be manufactured using the same input material and two different vacuum levels on two MRS extruders to deliver two melts with differing viscosities to the spinning beam.

Further applications for the MRS extruder include the processing of bottle flakes or production waste to car-pet fiber (BCF) and nonwovens — also as bicomponent fibers. By using 100 % PET bottle flakes, raw material cost savings can be achieved.

MRS based extrusion systems can be combined with any kind of typical fiber downstream equipment.

High quality fibres can also be manufactured with the unique MRS extruder. Up to 100 % recycled content can be processed, thereby reducing the raw material costs whilst minimising the energy costs.

• Efficient devolatilisation of water, monomers, oligomers and other contaminants

• Narrow molecular weight distribution, no low molecular components

• Low plate out (development of deposits on the spinnerets)

• High line availability

• Stable IV even when processing materials with varying residual moisture levels

• Accurate, adjustable control of different viscosities even with the same input material

• Highest melt purity even when processing 100 % recycled material

• Fine filtration 12 – 40 µm

• Masterbatch can be added in either liquid or pellet form (low requirement due to little yellowing of the material during processing)

• Uniform colour no clouds or spots

• Major energy savings, low space requirements
