The papermaking process starts with pulping and separation of coarse contaminants to prepare the pulp for the subsequent cleaning steps. Based on its many years of expertise, Voith Paper now introduces the latest technology within the BlueLine stock preparation – the IntensaDrum Duo, a two-piece drum pulper. The machine, suitable for recovered paper, is perfect for very high production volumes and is characterized by extreme robustness and high reliability and efficiency. The two-piece modular design corresponds to the IntensaDrum ID45XL, which has been used successfully many times for smaller production quantities.

Maximum robustness for large production volumes
How well the machine concept works in practice is demonstrated by the installation of the IntensaDrum Duo at the company Progroup as part of the Taurus PM 3 project in Germany. With a diameter of 4.5 m each, the 48 m long drum pulper and the 23 m long screening drum have since then been processing 3,000 tons of recovered paper per day. The total length of the IntensaDrum Duo, which weighs over 300 tons, is 78 meters. This makes the stock preparation plant in the Taurus project the largest of its kind in the world.

Advantages of a two-piece design
In order to enable this high production volume with a one-piece drum pulper, the free hanging areas would have to be significantly enlarged. This would significantly increase the dynamic loads in all directions and lead to extreme design challenges. With the two-piece design, Voith has successfully overcome these technical limitations of one-piece single drums. The ability to run very high production volumes over one drum pulper and thus also over one stock preparation line leads to a significant reduction in investment and operating costs.

High mechanical engineering quality combined with long experience
IntensaDrum Duo processes the production volumes of two standard drum pulpers. As only one pulper is now required and the complete production is processed in one line, maintenance and servicing costs can be significantly reduced. At the same time, the IntensaDrum Duo impresses with its enormous robustness due to its modular design.

"The IntensaDrum Duo is based on the same drum design as the IntensaDrum ID45XL,” says Pierre-Haakon Berger, Global Product Manager for drum pulpers at Voith Paper. “Many customers use the IntensaDrum successfully for small and medium production volumes. When developing the IntensaDrum Duo, we were therefore able to utilize the experience from this size. Standard machine components also ensure high engineering quality in the design of the IntensaDrum Duo. Compared to a one-piece design, the two-piece IntensaDrum Duo offers significant advantages with these dimensions in terms of transport and installation."

Resource-saving process
Special lifting bars guide the suspension in the pulping area from the bottom and almost to the top. Once at the top, the suspension falls back onto the drum body. Since there is no rotor to reduce the size of the reject, the process is extremely careful. The fibers and reject are also gently separated in the screening section. In addition, water from the shower pipes can enter the drum through the screening area so that the fibers can be efficiently washed away from the reject. Also, the absence of wear parts results in a constant accept quality of the stock as well as lower production and shutdown costs.

Berger adds, "Due to the very gentle pulping process, the recycled fibers are disintegrated without shear forces. This process is particularly gentle on resources because foreign materials, for example plastic, are not destroyed and can therefore be sorted out at an early stage."

PAPRESA, the leading southern European manufacturer of newsprint, commissioned Voith in March to completely rebuild PM 5 at the Rentería mill in Spain. The start-up of the ambitious project is scheduled for the first quarter of 2022. Subsequently, the extensive rebuild will enable significantly more efficient and sustainable production of packaging paper. The capacity will then be around 205,000 tons of testliner and corrugating medium per year, with a PM design speed of 1,200 m/min. The focus of the new PM is on lightweight containerboard grades with 65 to 140 gsm, the wire width is 5,900 mm and the paper will have a web width of 5,400 mm at the reel. The production of newsprint will be maintained at PM 6.

  • PAPRESA awards Voith to convert the complete PM 5 of the mill in Rentería, Spain, to the most modern production of packaging paper. The production of newsprint paper will be maintained by the production at PM 6.
  • The full-line offering includes a comprehensive service and fabrics package as well as digital Papermaking 4.0 solutions.
  • Voith already received an order from PAPRESA at the beginning of the year to supply a complete new BlueLine stock preparation line for the use of recycled paper.

Cutting-edge technology for the PM 5
In addition to modifications in the approach flow system, the wire section will be upgraded with the DuoFormer D including new dewatering elements. Voith will also supply the DuoShake shaking unit and a MasterJetPro F/B headbox with ModuleJet I dilution water technology. Furthermore, to ensure the capacity increase of the paper machine, the existing press section will be extended with a NipcoFlex shoe press and converted to a DuoCentri NipcoFlex press. New EvoSteel steel cylinders with higher steam pressure in the last two dryer groups of the pre-dryer section are also part of the scope of supply. A film press with a subsequent new after-dryer section also increases the quality of the final paper. In addition, the existing reel is extended by the EcoChange W turn-up system for more efficient reel spool changes. Finally, the scope of delivery includes a comprehensive fabric package for the start-up of the PM 5.

Strong growth potential for packaging paper
In times of e-commerce, packaging papers are becoming increasingly important. As a full-line supplier, Voith delivers PAPRESA efficient and at the same time resource-saving solutions with the PM 5 conversion:

“This transformation is our answer to the declining demand in the newsprint market and the steady growth of the packaging paper sector, which is growing at 9 to 10 percent per year thanks to the tremendous upswing in e-commerce,” says Miguel Sánchez, President and CEO of PAPRESA. “The pandemic situation further accelerates the surge in demand, which creates good prospects for our post-investment results. On the other hand, we will continue to be the leading southern European supplier of newsprint. We are glad to have found the perfect partner for this change in the full-line supplier Voith.”

Extensive investment and development for highest plant efficiency
With this order, PAPRESA is pursuing an ambitious investment and development plan. Earlier this year, the customer already awarded the full-line supplier Voith to deliver an entire BlueLine OCC stock preparation plant for the Rentería mill in Spain. Also here, PAPRESA benefits from a service and digitalization package.

About PAPRESA
PAPRESA was founded in 1869 as Papelera Vasco-Belga in Rentería and in 1901 it was incorporated as Papelera Española S.A., a company that brought together several factories, including the one in Rentería.  By then the mill specialises in the newsprint segment. In October 1993, the PAPRESA S.A. brand was born, following its spin-off from Papelera Española. In 2007, the Alfonso Gallardo Group purchased the whole company's shares and, seven years later, it was acquired by the American fund KKR

In October 2020, the German industrial investment fund Quantum Capital Partners (QCP) acquired PAPRESA with the goal to implement a transformation and improvement process. In particular, the process focuses on the packaging segment and the circular economy.

The data and inventory management of products and consumables involves a considerable amount of administrative work. The new digital asset management tool OnCare.pmPortal now offers paper manufacturers an optimum alternative for increasing both the transparency of product data and the efficiency of the procurement system, while also facilitating the planning of maintenance periods and downtimes and increasing plant availability. Thanks to a direct connection to the Voith Paper Webshop, registered components can be reordered quickly, easily and without any risk of confusion. 

  • Maximum transparency of product data, run times and inventories
  • Optimally planned maintenance periods and downtimes
  • Rapid reordering of registered components via the Voith Paper Webshop

“With the OnCare.pmPortal, Voith has developed a powerful asset management tool that simplifies central data management and gives paper manufacturers an overview of key products and consumables in their paper machine,” says Richard Birkhold, Global Product Manager Asset Management at Voith. “This facilitates optimized documentation of activities such as maintenance, repair and replacement, and simplifies data maintenance.” A particularly convenient feature of this tool is that it allows employees to select the component they are looking for using a digital image of the paper machine and provides them with immediate access to all relevant product information.

“Every day, I coordinate maintenance measures and control numerous processes,” says Karl-Josef Uhlemann, maintenance manager for rolls at Schoellershammer in Germany. “With the digital inventory management tool, I can now manage consumables and rolls centrally and access the data at any time and from any place.” 

The OnCare.pmPortal now starts with two modules: The automated data recording of rolls and fabrics, as well as the digital inventory management of doctor blades. These product groups are automatically identifiable in the OnCare.pmPortal by means of a digital nameplate and do not require manual entry in the system.

ID tagging for rolls and fabrics: For constant visibility of product data and run times
The ID tagging module for rolls and fabrics is a combination of contactless, radio-based connection technologies and the integration of digital nameplates based on proven industry standards. The solution offers simple, user-friendly tagging of rolls and fabrics and enables seamless identification through the scan of a digital nameplate. Regardless of the technology standard, the ID tags can be read with a smartphone and the corresponding Voith app and managed in the OnCare.pmPortal. The mobile application grants access to all product data, at any time and from any location, for efficient tracking of the product history and optimized documentation of activities such as maintenance, repair and replacement. 

Karl-Josef Uhlemann explains: “Thanks to the combination of OnCare.pmPortal and the ID tagging module, I can identify a product directly via the digital nameplate or search the database. The mobile application with its intuitive interface provides a quick and easy overview of product information and important product lifecycle data.” 

Blade Inventory Management System: Digital control of inventory data and fully automated management of inventories
With the help of the Blade Inventory Management System module, the operator no longer has to worry about ordering doctor blades or the associated stock control and supply chains. This is made possible with an ID tag on the packaging of the doctor blades. New doctor blades are automatically reordered and delivered by the system as soon as the stock in the warehouse reaches a minimum, individually defined level. As soon as the new blades arrive in the customer warehouse or existing blades are removed from the warehouse, the stock is updated in the OnCare.pmPortal and can be accessed from there at any time, thus increasing inventory traceability and transparency. At the same time, there is no need to maintain inventory lists or carry out inventory controls. As a result, the OnCare.pmPortal not only reduces the outlay and costs associated with inventory management, but also increases its efficiency by using automated and digitized processes. 

Voith plans to extend ID tagging to additional consumables and components in the near future and, in doing so, will offer paper manufacturers an even more powerful tool.

On January 10th, Sun Paper started up a new packaging production line PM 2 in Laos. As the 6th packaging paper machine that Voith supplied to Sun Paper, PM 2 started up 18 days ahead of schedule and is Sun Paper’s second paper machine outside of China. From stock on wire to paper on reel it took only 1 hour and 46 mins. The team has thus set up a new start-up record for this type of paper machine.

  • Second Voith-supplied paper machine in Laos within one month
  • Start-up 18 days ahead of schedule
  • All six Voith-supplied packaging production lines put into operation
  • New milestone for Sun Paper “Forest-pulp-paper integration” strategy

Voith supported Sun Paper’s fast expansion in capacity and high-quality development with the start-ups of PM 1 and PM 2 just within one month. The tight schedule was a challenge but due to the strong collaboration and close project execution among Voith and Sun Paper, both paper machines started up ahead of schedule. Sun Paper’s “Forest-pulp-paper integration” strategy implementation achieved a new milestone.

“Based on our experience of PM 1, our team from Voith and Sun Paper further optimized feather and parameters of the second machine,” says Aimin Zhang, Laos Project Director from Sun Paper. “Consequently, PM 2 started up 18 days earlier than planned and it took only 36 days from I/O checking to first roll-out. This success proves again the expertise and know-how of both teams, as well as the close collaboration. I believe that PM 2 will soon achieve the highest performance level. I would like to thank Voith for the great contribution.”

2021 01 25 085052

The Laos project is Sun Paper’s “Going Global” strategic expansion, which has already shown the company’s insight and competitiveness by taking advantage of the region’s rich forest resources, geographic location, and future tax privileges brought by the regional comprehensive economic partnership agreement. PM 1 and PM 2 have helped to increase the proportion of high-quality packaging paper, and the two efficient and reliable paper machines strengthened the cost competitiveness. The two machines are installed in the same workshop, while PM 1 is the right-hand machine, producing paper with basis weights of 140-250g/m2 and an annual output of 520,000 tons; PM 2 with left-hand machine direction is producing low-weight products with a range of 100-160g/m2 and an annual capacity of 480,000 tons.

The start-up of PM 2 also signifies that all packaging paper machines operating at Sun Paper are provided by Voith. Sun Paper partners with Voith from its first entry into the packaging paper business, co-worked on the structural optimization under supply-side reforms in China, and now, the overseas project witnessed the collaboration during Sun Paper’s global expansion. The development of Sun Paper’s packaging paper is a journey of innovation and also one in which Voith is always present to provide the best possible solutions and services to its customers.

The Ilim Group in Russia had been planning for a long time to upgrade the PM 4 at its plant in Koryazhma by adding a new MasterJet Pro headbox. However, due to pandemic-related travel bans the installation team from Heidenheim was not able to get to the site by the scheduled date. Nevertheless, a clever solution was found: Using the remote video support tool OnCall.Video, the Russian team on site was able to access Voith expertise in Heidenheim in real time. Thanks to the use of the audio-visual communication system, the rebuild was completed on schedule despite the travel restrictions and implemented in a very short period of time. The result is a significant increase in paper production efficiency and a highly satisfied customer.

2020 11 03 111611

The Ilim Group is Russia’s largest manufacturer of paper and pulp with a production capacity of three million metric tons per year. To reduce operating costs, improve paper quality and minimize maintenance, the company planned to replace the existing headbox on the PM 4 at its plant in Koryazhma, in the north-west of Russia, with a new MasterJet Pro headbox. However, the retrofit scheduled for April had to be deferred because the German installation team was not able to travel due to official restrictions. Thanks to Papermaking 4.0, however, an alternative solution was found: Using the remote video support tool OnCall.Video, the experts from Heidenheim were able to provide support to the Russian team in St. Petersburg. “Thanks to our web-based video collaboration platform, our highly specialized expertise is available immediately worldwide at all times, without the need for anyone to travel,” explains Werner Goebel, Director Project Management at Voith Paper.

A worthwhile rebuild that immediately produced marketable paper

The new MasterJet Pro headbox ensures optimum paper quality, low operating costs and cost-effective maintenance. For minimal maintenance shutdowns, for example, system components like lower and upper lips and separating wedge can be replaced quickly and easily. In addition, the system is designed for uncomplicated grade changes. This offers Ilim Group a high degree of flexibility in production. Thanks to OnCall.Video, the entire installation went according to plan. The PM 4 was able to operate again immediately after the retrofit, and since then has been producing high-quality, marketable paper in a range of grades and grammages. The customer is impressed not only by the smooth installation process but also by the excellent result. “The performance of the upgraded paper machine has actually surpassed the project objective,” says Alexander Pozdnyakov, SVP Operations at Ilim Group.

LEIPA is the world’s first paper mill to employ virtual reality (VR) from Voith as a modern and immersive training method. At the Schwedt location, the company trains its employees extremely effectively using the VR system. To perform the installation in spite of the contact restrictions imposed as a result of the coronavirus pandemic, Voith and LEIPA drew on a new tool for remote video support: OnCall.Video. LEIPA has been using this audiovisual communication system with wireless data glasses since January 2020.

With the VR application, LEIPA employees can complete hands-on training in the computer-generated environment at any time and without any danger. From simple exploration of a paper machine for newbies to the complex process of changing the press sleeve on a modern shoe press, the system offers every employee a completely new training experience. This is made possible by 3D visualization in a headset combined with control devices for the interaction. The employee can move freely in the virtual reality setting and is guided through various tasks step by step.

2020 10 15 155959

Specifically for the VR training from the Voith PaperSchool, LEIPA set up a futuristically designed room, the "LEIPA Virtual Reality Center," at the Schwedt location. A special design and lighting concept underscores the modernity of the VR technology. Voith also supplied a touchscreen and wireless VR equipment to meet the special customer request for a cable-free studio.

How the OnCall.Video remote video support tool can increase efficiency and thereby give customers traceable added value became clear with this start-up. "The room was already prepared and the sensors attached," recalls Patrick Dengel, Digital Tools Manager at Voith. "We handled the details via OnCall.Video. To accomplish this, the glasses were integrated into the LEIPA WLAN, via which a video and audio connection to the Voith experts in Heidenheim was established." Without the remote connection, the VR system would not have been functional as quickly.

2020 10 15 160054

OnCall.Video offers LEIPA clear advantages especially for problems in the production flow, because the papermaker can draw on know-how outside the company to find solutions with virtually no delay and with cost savings. "Required expert knowledge is not always available on site, so integration of external know-how is that much more important," stresses Patrick Dengel.

"In principle, I can guide everything with the tool," adds his colleague Stefan Endras, Product Manager, OnCall.Video. "Our main emphasis is on quickly connecting the customer with the experts. In this way, we can also partially compensate for the lack of skilled workers." However, added value is also offered to the customer through the fact that various locations can easily be connected to each other and, as a result, internal exchange of specialized information and knowledge transfer are promoted.

2020 10 15 160028

With the virtual reality solution and OnCall.Video, LEIPA underscores its digital competence. "Which papermaker can claim to have the most modern media in use before anyone else?" argues Steffen Deszpot, Senior Manager Maintenance at LEIPA. "Industry 4.0 has already arrived here – and we are happy to show it."

Voith introduces a new screen plate design for pulpers used in recovered paper pulping. The CurvedBar screen plate extends service life in Voith's IntensaPulper IP-R by more than 50 percent and improves the quality of fiber suspension. The results are less maintenance effort and material use, as well as fewer downtimes, leading to a more efficient overall process and lower costs. Chinese paper manufacturer Shanying International Holding Co. LTD., has tested the CurvedBar screen plate on its PM 5 in Maanshan and is now equipping other pulping systems with the innovative solution.

"With the new CurvedBar technology, we substantially reduced downtime and extended maintenance intervals at the pulper with consistently high operating quality," says Wan Tao, Vice President Production at Shanying International Holding Co. LTD. "We also achieved very positive results from the coarse screening."

  • Innovative screen plate geometry with more than 50 percent longer service life
  • Optimal interaction of pulper, rotor and screen plate for a higher quality fiber suspension
  • Reduced costs for operation and maintenance

To reduce the high mechanical loads on the screen plate, Voith developed an innovative curved bar design and optimally matched to the geometries of pulper, rotor and screen plate. "This results in a much longer service life compared to conventional screen plates," explains Oliver Lüdtke, Global Service and Product Manager at Voith Paper. The lower friction also reduces energy consumption. "Combined with savings in material and maintenance, significant cost-saving potential can be realized, and the customer’s carbon footprint is reduced due to greater sustainability," says Lüdtke.

Lower shearing forces, higher quality fiber suspension and problem-free ragger formation
Thanks to the lower shearing forces on the screen plate, far fewer contaminants are shredded. This improves the quality of the fiber suspension, reduces the amount of small rejects that need to be laboriously removed in the downstream process steps, and allows trouble-free ragger formation. Furthermore, the risk of bar breakage and deformation of the screen plate is significantly reduced. The CurvedBar screen plate has proven its effectiveness at Shanying in Maanshan, China, and other locations.

"With the new curved technology and premium W material, we optimized and reduced the flake content and are maintaining high-efficiency pulping performance in the long term," says Song Jie, Manager of the Technical Department at Shanying International Holding Co. LTD. "The flake content is about 15 percent, the lifetime of high-efficiency pulping performance is extended from two months to five months."

"We still keep very good collaborating relation with Voith for the OCC stock preparation and paper machine, especially for testing the performance of the screen plate with CurvedBar and premium W material," Jie adds. "We value the excellent and professional support provided by Voith during installation and commissioning of the screen plates. At all times, Voith was in close contact with us to continually optimize the equipment. We are very satisfied with the results and happy to have Voith as a strong partner by our side."

Following the successful pilot phase, the company has already awarded Voith several follow-up orders to successively retrofit other pulpers with the new components. Other customers have also placed repeat orders for the innovative screen plate design following successful testing.

In early 2017, Voith received an order for six BlueLine OCC stock preparation lines from Nine Dragons, the largest manufacturer of packaging paper in Asia. With the recently commissioned PM 41 at the customer’s Hebei site, five Voith BlueLine OCC lines, each with a production capacity of 2,000 tons per day, have now been successfully launched. The handover of the sixth line is planned for 2022.

  • The new capacity with Voith machines strengthens Nine Dragons’ leading position as Asia’s biggest recycled paper manufacturer
  • Voith BlueLine OCC portfolio supports Nine Dragons’ sustainable and low-carbon development philosophy

Nine Dragons is leading the industry in sustainable paper manufacturing based on the management philosophy "no environmental management, no papermaking." The continuous expansion of new production capacity benefits Nine Dragons in strengthening its leading position in the packaging industry.

2016 09 22 073412The five OCC stock preparation lines are the sole expansion that Nine Dragons has carried out over the past three years. Voith received the contract as the full-line supplier to deliver the entire approach flow systems together with the complete stock preparation portfolio.

While China is implementing restrictions on recovered fiber imports and stringent environmental regulations, papermakers are partnering up with suppliers who are offering leading sustainable solutions and technology in plant operations and stock preparation. Voith’s complete OCC solution creates sustainable and eco-friendly competitive production lines with 15 to 20 percent reduction in energy consumption and at least 0.5 percent fiber savings.

The Nine Dragons project demonstrates Voith’s ability to collaborate and manage the installation and commissioning of multiple orders on time, even under a tight project schedule and with the impact of COVID-19. When the pandemic strongly affected the project due to traffic and logistics interruption, Voith used all means of communication to collaborate with its customer. With a proactive and problem-solving attitude, the Voith team successfully completed the projects.

The digital solution is device-independent, so any device can be used for communication purposes. To perform servicing work with the machine still running, the technician can also wear industrial-grade smart data glasses that allow optimum communication with the Voith expert thanks to integrated voice control and active noise cancellation. Moreover, the smart glasses allow operators to keep their hands free, are splash-proof and dust-tight, and are compatible with the necessary PPE.

Wide-ranging applications for improved machine availability and productivity
“With the help of OnCall.Video, we can quickly analyze mechanical or technological problems and then recommend specific courses of action,” says Patrick Dengel, Manager Remote Solutions at Voith. “In addition to problem analyses, inspections and general service support, the system can also be used to assist with factory acceptance tests and commissioning.”

“Following an emergency in the wet end of our PM 1, the local Voith service team was able to carry out the necessary repairs quickly and professionally with expert support via OnCall.Video,” says Franz Gstettenhofer, Authorized Signatory and Member of the Management Board at Lenzing Papier GmbH in Austria. “This reduced the machine downtime and we were able to restart production shortly afterwards.”

Knowledge transfer across locations
Apart from providing a way to connect quickly with Voith experts, OnCall.Video can also improve knowledge transfer within a company. “This is an option both for our customers, who can then optimally connect their various sites with each other, and for Voith,” says Stefan Endras, Product Manager OnCall.Video at Voith. “Using OnCall.Video, collaboration between specialists across all distances can be accomplished quickly and easily. We have already been able to use the solution successfully for service assignments without the expert in charge having to travel to the relevant site.”
