Toscotec to rebuild a dryer section at Cartiera di Ferrara


rebuilt by Toscotec. The Ferrara mill’s paper machine


T


produces coreboard in the range of 220 to 620 gsm, using 100 per cent recycled paper. The rebuild will increase the mills’ output by 30 per cent when completed in the third quarter of 2020. The project includes two


dryer sections. In the first part, Toscotec will install new felt, guide and stretcher rolls; modify the existing frame structure and supply a new frame section. The second part will be completely new and it will feature 16 TT SteelDryers with a diameter of 1,829mm designed for an operating steam pressure of 10bar. The order also includes bearings and housings, steam fits and joints, turbulence bars for the dryer cans, and all the main section components such as felt


rolls, stretchers, guiding devices, and doctors. Toscotec will supply mechanical


drives for the entire dryer section in silent drive configuration. The services package includes mechanical erection, supervision, commissioning, and start-up assistance. The existing 1,500mm-


diameter cast-iron dryers will be moved to the first part of the dryer section. Toscotec will increase thermal efficiency in the second part using TT SteelDryers


with a larger diameter. Giulio Spinoglio, chief executive of Cartiera di Ferrara, says: “Out of the various proposals we evaluated for this project, Toscotec’s rebuild solution was the most compelling one for two main reasons. First, the timeline of the project: Toscotec gave us good guarantees on the PM1 shutdown time and their previous record of successful rebuilds confirmed their capability to deliver. Second, their technical solution was the most advantageous for us in terms

of production increase and energy efficiency. ” Enrico Fazio, sales chief at


Toscotec Paper & Board division, added: “Our rebuild solution allows for a significant increase of PM1 production capacity, without changing the length of the dryer section. This means that the positions of the press and the pope reel remain unchanged so that civil works will not be required, thereby significantly reducing the machine shutdown time.”


Brown stock washing system upgraded at the Gruvön mill


BillerudKorsnäs has ordered key process equipment to complement the main brown stock washing system preceding the side line for its board machine at the Gruvön mill in Sweden. The order from Andritz


includes a Compact Press which is said to have a small footprint and high availability including high washing efficiency, thus ensuring the production of high-purity pulp used for food packaging. When installed in 2021 it will offer


Screw Press for the new brown stock washing side line, which was started up in 2019. BillerudKorsnäs is a leading


output of more than 6,000 admt/d/unit.


A Compact Press from Andritz will be part of the Gruvön mill order Andritz also supplied the DD-


Washer, MC pumps and a pulp


player for liquid packaging board and a global leader in the production of high-porosity sack paper manufactured from primary fibres. In Europe, the paper maker is a leader in primary fibre-based kraft paper, fluting, and pure white liner and is also one of the largest producers of cartonboard from primary fibres.
