Drum pulper raises quality of ISMA 2000’s tissue products
T
o raise the quality of its tissue products, Spanish manufacturer ISMA 2000 SL has started up
a new drum pulper supplied by Andritz. The FFD225 FibreFlow drum pulper, replacing an existing machine, processes a range of recycled fibre materials with a feed capacity of 120 tons per day. In addition to supervising the installation, Andritz also included engineering services, start-up, and commissioning support. Using 100 per cent recycled
paper, ISMA 2000 produces its environmentally-friendly tissue papers with the brand name Ismax, ranging from mixed and sorted office waste and coloured ledger to various card and paper board grades as well as packaging and laminated paper. For these raw materials, the
reject content to be removed by the pulper ranges from two to 20 per cent. With the FibreFlow drum pulper,
a variety of cheaper waste paper raw material composites can
be used, without compromising the performance of pulping and paper production. The design of the FibreFlow enables a reduction of the installed power for the pulping process as well as
enabling paper producers to use raw material mixtures from used beverage cartons and polyethene- coated papers to used corrugated containers and office waste grades.
Langerbrugge mill chooses Siemens for its control systems
Stora Enso’s paper mill at Langerbrugge in Belgium has replaced the drives and control systems on one of its machines to better enable it to communicate with other devices in the plant. Stora Enso says it attaches
great importance to recycling material and developing and using renewable energy, which is why Siemens was chosen to provide the drives and controls. Chris De Hollander, managing
director of Stora Enso Langerbrugge, said: “We are
July/August 2016
opting for Siemens expertise because they provided a great deal of positive input in the project to create the most efficient solution that was within our budget.” Tommy Wagemans, business segment manager of the fibre industry department, added: “This is a complex turnkey project. To minimise downtime we have to be able, in the space of just one week, to deliver and install the necessary components and then get the paper machine up and running again. Considering
the size of the system, this is a challenging order.” Stora Enso produces 555,000
tonnes of recycled newsprint and magazine paper a year using two paper machines. When either machine is stopped every second counts. So besides the complexity of the system, the short time span in which everything must be completed is of crucial importance. “We are proud that Stora Enso has chosen Siemens to bring this project to a successful conclusion”, says
Christian Hacken, execution manager of Siemens’ Fiber Industry department. “It’s a complex order in which a lot is involved. Firstly a very specific new machine guideline must be implemented as regards integrated safety for people and machinery (EN1034). Secondly the upgraded machine, which will now run on our Simatic PCS 7 software, will also have to be able to communicate with existing ABB protocols of other devices in the company, including AF100-bus.”
