The new approach flow system for the top wire consists of IntegraGuard and MultiScreen screens and the associated pumps. The headbox is a MasterJet Pro. The former section was extensively modernized and a new TopFormer F installed to further improve dewatering and quality.

In addition to the machine rebuild, Voith also undertook the basic engineering and supervised commissioning. The rebuild and assembly took just ten weeks and the warranted parameters for the machine were successfully achieved within three months after startup.

Not only did the rebuild of the wet section of the BM 1 improve board quality: following startup of the new semi-chemical pulp mill – and depending on a few other technical measures – the production capacity of the BM 1 will also be increased in the future.

APPM is owned by Pulp Mill Holding GmbH, an Austrian-German Group headquartered in Vienna. The company produces paper, board and corrugated grades in Russia and Ukraine.

Screening plays a key role in the preparation of recovered paper, as it not only removes coarse contaminants but also small and very fine impurities. Papermakers expect low fiber losses, low energy consumption and effective removal of stickies. The BlueLine product range for stock preparation has been developed to meet these requirements. The latest product from the BlueLine family is the C-bar HerculeX screen basket.

2015 08 27 084127

The IntegraScreen and IntegraGuard from Voith are two screening machines for stock preparation and the approach flow system. In combination with rotors and screen baskets, they are adapted to the specific requirements of paper manufacturing.

IntegraScreen: a screening machine concept turned on its head
IntegraScreen is the screening machine for various applications in the stock preparation. With its development of IntegraScreen, Voith has literally turned its screening machine concept upside down: It differs from its predecessors since the intake for the suspension is at the bottom and the outlet for the rejects is at the top. For the first time in this solution, the light contaminants are separated along with the reject via the same pipe. The advantages are obvious: there is no need for additional piping, instrumentation, pumps and valves. A cone in the machine optimizes the flow on the accept side and ensures uniform pressure conditions over the screen basket. This evens out the screen passing velocity and as a result improves the efficiency of contaminant separation.

IntegraGuard: high-quality protection in the approach flow system
IntegraGuard is the screening machine for the approach flow system, where it is particularly important to prevent pulsations, deposits and stringings because they can cause sheet breaks. This is why the IntegraGuard housing is designed to achieve a homogeneous screen passing velocity. The new head piece improves the flow profile in the machine and allows to reduce the rotor speed while maintaining the rotor’s efficiency.

C-bar HerculeX: Hybrid technology makes for a strong screen basket
The C-bar technology used in screen baskets to achieve effective screening with fine slot geometries was first launched on the market by Voith more than 25 years ago and has been constantly refined and improved ever since. The new C-bar HerculeX is regarded as the strongest screen basket on the market to date and can withstand very high loads. It is made of wear-resistant material and is suitable for various applications in pre-screening and fine screening, fractionation, broke and thick stock screening and also in the approach flow system. C-bar HerculeX has very large open screening areas and a special bar geometry. The new screen basket can be tailored to the respective screening requirements and production conditions by varying the widths, slot widths and angles of the bars.

Its exceptionally high stability and strength are thanks to its patented hybrid technology, a reworking of Voith’s clamping technology. An individually customizable chrome layer provides wear protection. The screen basket can be used in all Voith and third party screening machines and is suitable for all paper grades. The best screening results are achieved in combination with a Voith rotor.

MultiFoil rotor and EclipseRotor Voith offers various rotors for its screening equipment, most notably the EclipseRotor and the MultiFoil rotor. The EclipseRotor was developed specifically for screening applications with a high level of contaminants. It is suitable for energy-efficient use in stock preparation and pulp screening and can be installed in Voith screening equipment and in centrifugal pressure screens from other manufacturers. Thanks to its flat but effective foil geometry, the EclipseRotor generates strong suction and achieves a very high stock throughput with very low energy consumption for pulp consistencies up to 5%.

Voith’s MultiFoil rotor was developed for use in the stock preparation and approach flow systems. Its special foil geometry prevents stringings and undesirable pulsations. Optimum suction impulses and a uniform flow profile combined with a low rotor speed help to make the screening process gentle and energy-saving. The MultiFoil rotor can be installed in the two Voith screens, in all vertical screens and in the machines of other manufacturers for centrifugal pressure screens.

Low costs for inventory and maintenance. The screening machines, screen baskets and rotors from the BlueLine product range are easy to operate and easy to maintain. Their spare and wear parts are standardized, allowing life cycle costs to be optimized.

DS Smith, an Italian market leader in containerboard production, has reduced maintenance costs and increased its paper quality and machine productivity thanks to the OnQ Profilmatic control system and OnQ ModuleJet headbox actuators from Voith.

2015 08 11 105517

The company's mill in Lucca, Italy, was experiencing inconsistent paper profiles and wrinkles due to the former actuator control of the existing control system of its PM 2. Voith recommended the OnQ Profilmatic cross profile control software, which is part of its modular and flexible Voith ComCore platform to optimize the shape of the profiles.

“Our existing system was obsolete. The actuator delivery time was a problem and we were spending too much on maintenance," said Stefano Andreotti, Technical and Technology Manager at DS Smith.

"Our production engineers are now very happy with Voith's OnQ Profilmatic. The system automates a process that before was entirely manual. Wrinkles have been reduced, and we are pleased with the deviation of the profiles,” said Andreotti.

The OnQ Profilmatic has the ability to determine the portion of random noise in the measurements. Continuous, dynamic profile mapping allows exact local mapping of the actuator control zones to the measurements and leads to better paper quality.

A major part of the Voith ComCore platform is the OnView information system, which makes all the details of the papermaking process available for analysis. This is the key to continued performance improvements for the machine. With this powerful toolset Voith accompanies DS Smith to achieve further efficiencies on the PM 2.

Voith has launched two new forming fabrics, designed for manufacturing demanding board and packaging papers and also graphic grades. As the names of the MultiForm IR and MultiForm IC suggest, these forming fabrics are part of Voith’s I-Series. All products in this series are based on a unique SSB concept. The special feature of the fabrics in the I-Series is their warp ratio of 3:2.

2015 07 22 114319

The new forming fabrics were specifically developed for positions that put high demands on dimensional stability and dewatering performance. The unique warp principle of both MultiForm forming fabrics combines a fine paper side with an extremely stable machine side. This allows an increase in paper quality and a longer service life for the fabric. Further benefits are the good runnability of the fabrics at high speeds and their positive impact on resource consumption.

Voith’s I-Series has already been used to produce around 14 million metric tons of paper worldwide. The I-Series forming fabrics are being used in a wide range of applications from fine paper through to demanding packaging papers and are suitable for all kinds of former types.

voith logo 2013Voith has successfully completed the modernization of the paper machine PM 6 at BillerudKorsnäs AB in Gruvön, Sweden. As part of the rebuild project, the press section and parts of the dryer section have been modernized. BillerudKorsnäs manufactures on the PM 6 fluting for packaging paper from virgin fibers.

In the press section the existing roll press was taken out of the second position and installed in the first press position. Now a new NipcoFlex shoe press is being used as the second press. The NipcoFlex package delivered to BillerudKorsnäs is the first one which can achieve lineloads of up to 1,700 kN/m. This is only possible through an optimal combination of roll, shoe, press sleeve and press felt, which were all developed by Voith. Through the extremely high press pulse maximum dewatering is achieved with the highest paper quality. The closed web run through the press reduces sheet breaks and increases the runnability of the paper machine. Dryness and speed of the paper machine are increased simultaneously. In addition, the cantilevering structure in the shoe press position of the new press allows the use of endless felts.

For the conditioning of the press felt a ProLub cleaning system has been installed for the first time in a paper machine for packaging papers. ProLub cleans continuously the felt across the entire working width. The dryer section has been reduced by two dryers, resulting in further energy savings.

Also part of the scope of supply were MultiFlex machine clothings in the press and dryer section and an OnQ ModuleSteam steam box that ensures a uniform CD moisture profile and a higher dryness.

BillerudKorsnäs AB, headquartered in Solna, Sweden, emerged in 2012 from the merger of Billerud and Korsnäs and is one of the leading manufacturers of packaging paper made from virgin fibers.

voith logo 2013The new PM 5 for light-weight packaging paper at Modern Karton went into operation on time in Corlu, Turkey, in the middle of 2015. The entire process technology – from the stock preparation to the winder, including automation – was delivered by Voith and is characterized by low fresh water and energy consumption.

Decisive for the choice of supplier were Voith's references in the field of light-weight packaging paper and good experience in working with Voith. Ahmet Eren, managing director of Modern Karton, confirmed: "The comprehensive technological experience of Voith and the sustainability concept of the system convinced us. With this project we can build on our position in the market."

PM 5 is designed for a production speed of 1,500 m/min and has a wire width of 8,180 mm. It produces around 400,000 metric tons of packaging paper annually with a basis weight of 70 to 160 g/m². "We offer paper manufacturers in this growing market segment convincing, attractive solutions. Our system concept is perfectly adapted to the requirements of this market and our customers benefit from resource- and cost-effective, high-quality machines," said Andreas Endters, member of the Voith Paper Board of Management.

The modern stock preparation system comprises two lines and is specially designed for the high percentage of rejects in Turkish waste paper. Also the consumption of resources of the paper machine is as low as currently possible thanks to the technology supplied by Voith. For example, due to the installation of the innovative FlowJec dosing system in the approach flow system of PM 5, it is possible to exactly coordinate the use of chemicals. In addition, the OnV EnergyProfiler software localizes and visualizes all the energy consumption during paper production. Added to this are the automation, rolls and first clothing for the machine as well as all additional services and auxiliary packages. Voith has conducted extensive training for new staff and provides additional technology support. Modern Karton itself has set up a power plant on the mill premises to utilize the residual materials from the production process and to generate energy.

The Turkish company Modern Karton is part of the Eren group and is one of the largest manufacturers of board and packaging paper in Europe. At its Corlu location, 120 km west of Istanbul, 630,000 tons of packaging paper were produced annually on two machines prior to the startup of PM 5, both for the domestic market as well as for the export market. With the new machine the production will reach 1.2 Mio tons, which represents approx. 50% of Turkey’s total production capacity. Modern Karton has now further expanded its leading position in the market of packaging paper producers in Turkey.

Steel cylinders for the dryer section

EvoDry a winner at WEIG-Karton

2015 07 09 091141

Compared with cast iron cylinders, steel cylinders offer impressive features like higher thermal conductivity and greater material strength. These and other benefits mean that it makes good sense to install steel cylinders when upgrading dryer sections. Recently, WEIG-Karton also opted to install EvoDry steel cylinders at its plant in Mayen, Germany.

2015 07 09 091230Because EvoDry steel cylinders for the dryer section have high material strength they can have a thinner wall thickness than comparable cast iron cylinders. The temperature distribution in EvoDry drying cylinders is very even, which ensures optimum paper quality. The head and shell of EvoDry cylinders are welded to one another, so that larger sheet widths can be passed over the drying cylinder. The high material strength and low wall thickness of the steel cylinder result in higher thermal conductivity, improving heat transfer by 7 – 10 %. Thanks to this high efficiency, production can be stepped up or investment cost minimized when using EvoDry, as fewer drying cylinders need to be installed.

On two machines in Mayen, WEIG-Karton produces recycling board for the folding boxboard industry and plasterboard for the plasterboard industry. Total annual production is 630,000 metric tons of board. In 2014 the company decided to rebuild the dryer section of its BM 6 plasterboard machine. Voith won the order to convert the dryer section and installed a total of 31 EvoDry steel cylinders. The board manufacturer opted in favor of steel cylinders to achieve the maximum possible drying efficiency. As well as supplying the cylinders, Voith was also responsible for assembly and commissioning.

The rebuild of the dryer section was a smooth and fast process. After just 19 days, WEIG-Karton could resume production of plasterboard on its BM 6. “We are absolutely delighted that the rebuild was accomplished so quickly and smoothly,” says Henning Dippel, Operations Manager BM 6, adding: “We are equally pleased about our decision to install the EvoDry steel cylinders. We have been able to save space and yet achieve better runability and energy efficiency than before.” Shortly after startup of the EvoDry steel cylinders the guaranteed CD moisture profile values have already been achieved.

EvoDry drying cylinders can be used for the production of all paper grades. Optimum results are achieved with paper grades that are dried at high temperature, for example board and packaging papers.
