Approach flow systems ordered for Spremberg mill


H


amburger Rieger GmbH has ordered three paper machine approach flow


systems and broke screening for its new greenfield PM2 line at Spremberg in Germany from Andritz with start-up scheduled for mid-2020. The paper machine, with a


capacity of 500,000 tons per year, will produce both brown and white top test liner. The PMA systems for the top and back layers will be equipped with Andritz ShortFlow Deaeration systems, comprising


deaerators, the corresponding vacuum pumps, as well as ModuScreen HBE screens for stock and dilution water screening. The


patented ShortFlow Deaeration system enables effective air removal with partial deaeration. In comparison with conventional


Dewatering press for Metsä Board’s Joutseno mill in Finland


Metsä Board’s Joutseno mill in eastern Finland has ordered a dewatering press from Valmet with start-up planned for October 2020. The TwinRoll VPE 1245 press will be used for bleached chemi-thermomechanical pulp


production. The mill has capacity for 330,000 tons a year which is used for Metsä Board’s own folding boxboard production. Toni Tahvanainen, mill manager


at Joutseno, said: “Metsä Board is investing in improving the energy efficiency of its Joutseno


chemi-mechanical pulp mill. This investment increases the dry matter content of the pulp going to drying and saves energy for drying. Natural gas consumption will be reduced by 20 per cent.” Lari Lammi, senior process manager for pulp and energy


deaeration concepts on the market, ShortFlow Deaeration has an extremely small footprint. The third PMA system will supply


the back layer headbox with white water for cross-profile control. A two-stage broke screening system completes the scope of supply. Hamburger Rieger is part of


the Hamburger Containerboard Division of the Austrian Prinzhorn Group. Producing two million tons in seven plants, Hamburger Containerboard is one of the leading producers of high-quality corrugated board in Europe.


business at Valmet, said: “Metsä Board decided to place this order with Valmet based on our good references for TwinRoll presses. It is an important milestone for Valmet to install the largest VPE press type in to a bleached chemi- thermomechanical mill for the first time in Finland. The press will enable Metsä Board to increase and stabilise the pulp consistency to the flash drying, thus reducing impact to the environment.”


More cooperation between Voith and Sun Paper in China


Sun Paper in China has ordered an 11th paper machine from Voith.


The new order is for PM39, a


graphic paper machine, along with major components for PM40, an MG paper machine. Both machines will be installed


at Sun Paper’s Yanzhou facility, where PM21, 24, 29, 36 and 37 are also located. With a width of 10.5 m and a design speed of 1,800 m/min, PM39 will have an annual capacity of 450,000


metric tons. The equipment for PM40 includes a MasterJet Pro FB headbox with ModuleJet, a complete press section with a Single NipcoFlex press and an EcoCal Soft calender. Earlier collaboration between Sun and Voith has resulted in: ● Both PM36 and PM37 starting up ahead of schedule


● PM37 setting a new record for packaging machines with 1 hour 57 minutes for stock on wire to paper reel.


Guangdong Ying, deputy general manager and chief engineer at Sun Paper, commented: “Voith is the leading company in the papermaking industry, and its XcelLine paper machines have been supplied for many outstanding projects globally. At the same time, Sun Paper has contributed greatly to the development of the Chinese paper industry. In joint cooperation with Voith, our PM36 and PM37 had very successful


start-ups. We like cooperating with Voith.”
