ANDRITZ 15 In North America, and a little
more reluctantly in Europe, the trend towards premium products continues, and we expect that to remain into the future. Interestingly we see in South America and China tendencies to consider the production of higher quality grades as well. This demand for higher quality is being satisfied with new technologies, which, from the energy usage point of view, are reasonably close to conventional tissue.
Q: Andritz has had some success in China, what do you put this down to? A: Andritz was one of the first European suppliers to bring advanced tissue machine technology to China, for example with new machines for Hengan and APP. Secondly, Andritz has extensive local capabilities in our workshop in Foshan which have been strongly enhanced over the last years in order to fulfil the request for local manufacturing and backed up by Andritz global quality management. Moreover, key components

however there is a clear direction change towards the installation of smaller and thus more flexible production units rather than the big machines as installed over the last years. We also expect the tissue market in South America to grow as well as strong development in Eastern Europe. In total, the investment dynamics have slowed down in comparison to recent years, but there is still potential for almost all market areas.
can now also be manufactured successfully in China according to highest Andritz quality standards for the global market, for example Yankee cylinders can be made at the Yankee manufacturing and Service centre in Foshan. Last, but not least, having a strong local service organization in China is a decisive factor for the majority of our customers in this region.
Q: What are customers demanding now in terms of raw material savings? How is Andritz responding to those demands? A: There is a clear trend for reducing the use of long fibres and increasing the percentage of short fibres used for tissue
production. In some regions, short fibres are used for the complete product range. It is important that refining
processes are optimised, for instance by the use of the Andritz Papillon refiner, which definitely provides for the lowest energy consumption when compared with other refiner types. Further energy saving
potential is given by the Andritz ShortFlowConcept by reducing the number and volume of tanks, which results in less agitating and pumping energy requirements as well as lower investment costs.
Q: Can you comment on the different types of fibre that Andritz tissue lines are suited for? A: Stock preparation lines are suitable for all kind of fibres. Beside the typical wood fibres, Andritz has good operational experience on some of our commercial machines with bagasse pulp and bamboo fiber, both bleached and unbleached. Further to this our stock
preparation research centre at Graz in Austria, as well as our commercial-size mechanical pulping pilot facility ‘R&D Center Springfield’ in Ohio, USA, have vast knowledge and extensive data for almost all existing fibres, including almost all annual fibres. Finally all these fibres can be tested in our Tissue Innovation and Application Center (TIAC) on a full-scale pilot tissue machine, in order to identify the impact on operational efficiency, product data and paper quality.
Q: Can you describe what Andritz can supply in terms of complete lines? And for what products? A: Andritz can supply complete turn-key production lines
from bale handling to reel, and, if needed, also rewinding and roll handling. We offer all technologies including complementary air and energy systems, sophisticated automation and electrification solutions, complete life-cycle services as well as best-in class tissue machine clothings. Our equipment such as pulpers,
refiners, screens, cleaners, headboxes, shoe presses, Yankees and hoods are manufactured in Andritz own workshops. In addition to our turnkey solutions we offer also an advanced Metris Portfolio helping our customers in the digital transformation of their tissue production line. This includes the Metris UX platform, Metris OPP and much more.
Q: Can you also describe what Andritz provides in terms of back up and service to customers? A: Apart from commissioning and start up assistance as well as optimisation after start-up on site, Andritz can provide dedicated remote support. From our Metris Performance Center in Graz we can fully support the operators on site, optimize the customers’ plant, adjust and change settings. The Metris Performance centre can take over all functions of the customers control room and can remotely operate all equipment if needed. Our Metris OPP (Optimization
of Process Performance) services represent a clear advantage for tissue producers to maximize efficiencies across their mills. These services are accompanied and secured by cyber security solutions, artificial intelligence, preventive and predictive maintenance services, as well as many other services.
