In-Line PCC™ process

IN-LINE PCC™ PROCESS – NEW TECHNOLOGY CUTS DOWN COSTS AND FORMS THE CORE FOR NEW PRODUCTION PROCESS

In-Line PCC™ process generates filler-fiber composites consisting of calcium carbonate and fiber. This fiber-loaded calcium carbonate filler is a new type of raw material competitive in quality, price and technology.The In-Line PCC process is extremely fast and therefore it can be integrated directly to paper/board production line. The production system is operated by paper/board mill personnel. This results to higher quality control and creates opportunities to reduce production costs. One of the significant process benefit is that there is no need to invest in separate PCC satellite production plant with long-term supplier contract.The process fits easily to large process lines with high capacity but also fits and adapts very well to smaller production lines. This offers an opportunity to smaller paper and tissue lines as well as e.g. white top board ply to exploit benefits of PCC filler.

The key benefits of the process

•     Attractive and price competitive filler material

•     powerful fiber loading effect

•     very high retention of filler and fines

•         retention aid consumption reduces up to 80 %

•         less filler penetrates through wires resulting to less wear and longer lifetime of machine fabrics

•     excellent strength and optical characteristics of the sheet

•     cleaner PM approach flow system

•     web formation is significantly improved

•     significantly lower investment cost
