INTRODUCTION:
Until now, Fourdrinier wire tables were designed for one main paper grade. At this grade, the activity of the fiber suspension as well
as the dewatering performance of the equipment was in an optimum range. When producing products which were much different to the
design grade, the activity level as well as the dewatering behavior could have been much different too. There were only limited adjustment
possibilities to compensate these negative influences. This article describes a solution to be able to adjust the settings for all paper grades
of a wide product range to an optimum.
These days the Pulp and Paper market is expecting a high
flexibility from operators as well as paper machines. Many mills need
to produce a big product range to fulfill the needs of their customers.
Up to more than 100 different paper grades, all produced on the
same wire table, are not uncommon. This leads to big differences in
production parameters. Machine speed or basis weight are only two
parameters which can be different by more than double.
These changed parameters of course do also influence the
behavior of the suspension on the wire table. The activity level can
change from totally flat to stock jumping, affecting the paper quality
significantly.
The SmartTable solution allows to optimize every paper grade
of a wide product portfolio with the highest efficiency and the
best properties.
The SmartTable consists of individual components – Smart
Foils, Smart Vacuum Valves and Smart Consistency Sensors. Each
of them can be adjusted individually but also used as a complete
solution package, which ensures a much better paper machine
performance with increased efficiency. Figures like the following
confirm the successful implementations at customers mills.
Röchling Industrial Oepping recognized this challenge for
papermakers early on and has been working on finding a solution for
years. The advancing digitization and extensive automation came
at just the right time. The company used its potential to develop
the new Robasmart product family. The naming consists of “Roba”,
which stands for the company’s affiliation with its roots - all product
groups from this company start with this name - and “Smart”, which
stands for the intelligence of this product family. A part of Robasmart
is the SmartTable. It defines the intelligent wire section solution for
optimized paper grade production by configuring the dewatering
elements, vacuum and dry content values.
Figure 2: Improvements using a SmartTable.
Due to individual settings on the wire table, following
improvements are possible:
1. Formation and paper strength improvement
2. Increased drainage capacity
3. Reduced energy costs
Let’s get in detail.
