Finnish company Valmet has secured a contract to provide an extensive recycled fibre line and paper machine grade conversion rebuild to Model Paper Eilenburg in Germany.
The project will involve the rebuilding of the paper machine, which currently produces newsprint grades, for the production of lightweight and recycled containerboard grades.
The rebuilt machine is expected to be operational in early 2024.
Valmet senior sales manager Tobias Hain said: “This is again a very interesting project for Valmet in Europe. The technology and references we presented to Model Group were well-suited.
“The production line has many technical highlights: a new linear double shoe press to improve machine runnability and end-product quality, and the extremely high-capacity winder and Valmet DNA Automation system for the whole machine line will ensure that the delivery meets Model’s goals.”
The scope of the grade conversion delivery consists of a rebuild of the DIP (deinked pulp) line, as well as OCC (old corrugated container) line, updates to stock preparation, and a rebuild of the board machine.
For increasing the capacity and the handling of brown fibre, the OCC line will be installed with upgrades to HC cleaning, coarse screening, and LC cleaning.
For the board machine rebuild, the delivery will consist of a shoe and blade technology upgrade in the forming section and a new OptiPress Linear press section. The drying section will be refurbished into OptiRun Single.
To enhance the drying efficiency and runnability and draw control, OptiAir Hood high-humidity hood, OptiAir Recovery heat recovery system, and other runnability, dryer and air system equipment will be delivered.
The delivery will also include a new OptiSizer Film sizer with a supply system, an OptiReel Linear reel, and a very high-capacity OptiWin Pro winder.
Valmet will also deliver a paper machine clothing package, in addition to maintenance master data for efficient and disturbance-free production.
The company will also deliver the latest generation Valmet DNA automation system, including built-in process control, machine control, sectional drive control, quality control, and condition monitoring.
Valmet IQ quality control system (QCS), Valmet paper lab, IQ web inspection system, IQ dilution profiler, IQ steam profiler, and IQ moisturizer will also be delivered.
With a 10,050mm-wide fabric, the board machine will produce fluting and testliner grades with a basis weight range of 70 –120 g/m2.
