Hamburger Rieger management now heavily invests in the Spremberg mill, situated in the federal state of Brandenburg. With its product line SpreeWhite, Spremberg mill is the quality leader in the segment of white corrugated base papers. Since the start of production of PM 1 in the year 2005, this paper machine has permanently been further-developed and so, in March 2014 the 2.5th million ton of paper was produced.
With a total investment volume of 18 million Euros, PM 1 will now be modified for the manufacture of coated white testliner (White Top Testliner). With this step, the product portfolio will be expanded with respect to quality.
Since Hamburger Rieger puts particular importance on innovative technology, it was not surprising that Bellmer was awarded the order for the upgrade of PM 1.
Bellmer will supply the coating tool TURBOCombi CoaterTM, combining proven technology with best reliabil-ity. This is the only jet coater on the market featuring separate base displacement for clear adjustability. Due to its particular large nozzle opening, the coater jet can be cleaned easily and fast.
The scope of Bellmer supply also includes new parts for the pre-dryer section and the dissolving pulper ahead of the sizer. A hard-nip calender will ensure the pre-calendering and the profiling of the paper web.
Pre- and post dryer sections will be re-configured, too. Here, the Bellmer subsidiaries Lang and Hafner are playing a leading role. The required changes regarding air and hood technology in the pre- and post dryer sections, extraction system of the new pulpers and modifications at the hood of the filmpress will be per-formed by Hafner. The steam and condensate system will be updated to the latest state of technology by Lang.
Since the main focus lies on an energy-efficient plant, Solaronics will provide an IR-dryer type UniDryer. The special feature here is that the heat quantity generated by the IR-dryer will be used fully for the following air dryer. Hafer will also take care of the air supply of both dryers.
Existing aggregates like the soft-nip calender and the pope reeler will be relocated. Bellmer has completely assumed the tasks of engineering, project management, dismounting, erection as well as start-up and train-ing of personnel.
Andreas Noss, managing director of Hamburger Rieger GmbH, concludes: "We have chosen Bellmer since they presented the most convincing overall package. That included - starting in the offer phase - detailed engineering work far above standard margins. Furthermore, we have come to appreciate Bellmer as a reli-able and competent partner during quite a number of rebuild projects they have implemented at our second location in Germany (mill in Trostberg, Bavaria)."
It is planned that the Spremberg mill will start production of coated testliners early 2015.
