New PrimeLine tissue machine for Arkhbum in Russia


R


ussia’s Arkhbum Tissue Group has ordered a tissue machine from Andritz for its mill at


Vorsino in the Kaluga region. Andritz will supply a PrimeLine W6-XT, including stock preparation, automation, and electrification, for the production of high-quality facial, toilet, napkin, and kitchen towel grades made of 100 per cent virgin pulp. Start-up is scheduled for the third quarter of 2019.


The tissue machine will have


a design speed of 2,100 metres per minute and a paper width of 5.6 metres. The combination of a 16-ft steel Yankee and the latest PrimePress XT shoe press technology will enable a high drying capacity. Andritz says it will achieve remarkable cost savings and operational flexibility compared to systems operated with conventional presses and cast Yankee dryers. The drying section of the machine will be equipped with a ReEvaporation system to reduce


drying energy costs. The system uses the waste heat in the hood exhaust to recover steam from the condensate stream, thereby reducing the amount of fresh steam required.


Also included in the order


is stock preparation with an approach flow system. This will have a Papillon refiner that treats fibres gently in the cylindrical refining zone to achieve improved fibre properties with low energy consumption. The approach flow system features the Andritz’s


ShortFlow concept, which reduces the number of equipment items and very low storage volume as well as fast grade/colour changes at the tissue machine. Andritz will also supply process pumps, piping, and instrumentation as well as on- site services. Irina Galakhova, executive


director of Arkhbum Tissue Group, said: “Our new tissue machine will significantly reduce the consumption of water and steam in the production process and also minimize costs in general.”


Release paper conversion at UPM’s Dörpen mill


UPM Nordland Papier is having a paper machine at its Dörpen mill in Germany rebuilt by Andritz to produce release/glassine papers. The rebuild of the PM2 machine will increase capacity at the mill to 110,000 tonnes per year when completed as expected towards the end of 2019. Andritz says the rebuild is


complex, with demanding technological requirements for the


equipment, process and products quality. In addition, Andritz will also modify the stock preparation system, approach flow and broke system.


The modification of the stock


preparation system includes ModuScreen CP police screens for the short- and long-fibre lines and two TwinFlo TF-S34 refiners for the long-fibre line. For the approach flow system, a new Short Flow


deaeration silo will be delivered including a vacuum system, new ModuScreen HBE headbox screens for the HC and LC lines, and fan pumps. In addition to these items, a two-stage broke screening system with ModuScreen F, a thickening drum PRS2060, and a deflaker DFL3 are included in the scope of supply. For broke conversion, Andritz will deliver an HC pulper FibreSolve FSH6 and an


additional deflaker DFL3. Every section of the paper machine will be modified. One of the key components is the PrimeFlow SW dilution water headbox. The PrimeForm and PrimeForm HB hybrid formers include new dewatering elements that are considered to provide maximum flexibility for dewatering and also improved sheet formation.
