4. What are the targets of refining?
Refining adjusts the fiber properties and consequently the technological properties of the furnish during the production process and the quality of the final paper
Most important parameters are:
Strength properties (wet and dry)
Air permeability
Formation
Bulk
What are the targets of refining?
It´s not the initial target to increase the dewatering resistance!
AFCP | Buenos Aires | | Oliver Lüdtke

5. Intensity of refining and specific edge load
In a long term research at Voith it was proven that each fiber species has an refining intensity where the properties are fully developed and the required energy consumption is on low level.
High intensity
Low intensity
SAME power transfer!

6. Adjusting the fiber structure by refining

7. Rough enviroment of papermaking
With the recycled paper a lot of trash is fed into the stock prep system
When problems happen in the system, sometimes it ends up in the refiner or disperger

9. Solutions to ensure proper refining Tough and wear resistant alloys
Pluralis SSF
1,3 mm bar width
6,0 mm bar height
Alloy STT
Ductile bending after foreign part enter the refiner
That filling could be used until next maintenance shut down

10. Refining performance is in the details
Innovative inlet design has an influence with contaminant rich pulps
Adapted groove design from inner to outer diameter
Voith Pluralis AO
Examples for NonVoith fillings
AFCP | Buenos Aires | | Oliver Lüdtke

11. Pluralis refines more fibers homogeneously
Sector
Guidance
Highly sectored design means uniform treatment from ID to OD
A controlled fiber guidance enables more fibers to be treated
Constant or widening groove opening from ID to OD is ideal for handling contaminants
This Is The Pluralis Effect!

12. Pluralis fillings for Tissue Increased volume and high softness
Volume and softness are essential factors in the production of tissue paper.
Fines from the refining process would be very unwanted here.
Refining with less edge load preserves volume and prevents the formation of fines.
As is known, Pluralis is a very fine filling which implements gentle refining.
Many satisifed customers confirm these favorable characteristics when refining for tissue.
AFCP | Buenos Aires | | Oliver Lüdtke

13. Statements from satisfied customers that changed to Pluralis refiner fillings
Pluralis plates resulted in same sheet strength at higher freeness (CSF)
Higher headbox freeness resulted in more then 100 m per min machine speed increase
Caliper (bulk) increased 3%-5% while maintaining tensile specs
Lower fines and improved drainage
The operators like the plates, the refiners are much more sensitive to slight changes in load
Able to shut down one refiner on some grades while maintaining tensile specs
Approximately 19% energy savings
Less dust in converting
25-45% lower starch usage while maintaining tensile targets
Reduced consumption of wet strength resin and improved haptics
