Business Areas Pulp and Paper 077 Paper Finishing Energy efficiency and cost savings continue to be important issues in the paper industry. For the tissue industry, the Division developed the smallest shoe roll ever built – with a diameter of only 710 mm. Patented features like additional lubrication and the edge relief system make it possible to obtain higher dryness without loss of bulk and with the fewest possible belt changes. Cost reduction is very often a question of reliability and availability. The Division’s R&D team came up with a new design for the PrimeFeeder technology that makes the entire process significantly more stable and helps reduce the time it takes a paper machine to reach full production after a sheet break. This solution has a patent pending. Paper Engineered Services The R&D focus is on improving the efficiency of equipment already installed in a customer’s plant to lower the operating costs. This involves optimizing the machine design to conserve energy and increase reliability, especially in the areas of sealing and wear technologies. An excellent example of such a value-added solution is the high-precision CONCEPT rebuilding program for Andritz Twin refiners. CONCEPT not only extends the time between major rebuilds, but also significantly increases the operational efficiency of the equipment. For dewatering machines, the focus is on introducing wear-resistant technologies for disc filters, Twin Wire presses, and screw presses from different manufacturers. State-of-the-art sealing technologies have been developed and are being retrofitted on these machines. For the pulping of stock, broke, and recycled fiber, a development program is in progress to enable up to 20% energy savings for the majority of pulpers installed in mills. In the automation area, a new optical sensor for measuring fiber properties online was introduced. The sensor requires significantly less maintenance and eliminates the need for intense recalibration often required for competitive units. This is a major step toward fully automated pulp production lines. The Division will continue to make modern technologies available for upgrades and retrofits of existing equipment, regardless of the original supplier, to increase the efficiency of each customer’s installation.
