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: et g r a t l a i t i he in It´s not t e the s a e r c n i e! c to n a t s i s e ng r dewateri AFCP | Buenos Aires | 2015 -05 -13 | Oliver Lüdtke 1.

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. SAME power transfer! High intensity Low intensity AFCP | Buenos Aires | 2015 -05 -13 | Oliver Lüdtke

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 AFCP | Buenos Aires | 2015 -05 -13 | Oliver Lüdtke

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! AFCP | Buenos Aires | 2015 -05 -13 | Oliver Lüdtke 11

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.

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 AFCP | Buenos Aires | 2015 -05 -13 | Oliver Lüdtke 13
