NEW C-BAR VERTECS SCREEN BASKET FROM VOITH IMPROVES STICKY SEPARATION EFFICIENCY BY UP TO 50 PERCENT AND SIGNIFICANTLY INCREASES THROUGHPUT
Paper manufacturers now have access to optimized screening technology in stock preparation. Full-line supplier Voith has developed the C-bar Vertecs, a new screen basket that sets new standards in terms of separation efficiency, throughput, energy efficiency and operational reliability. The technology is already being used successfully at heinzelpaper in Laakirchen, Austria. The C-bar Vertecs went into operation there as part of a trial comparison. Following installation and several hours of operation, Oliver Hunstein, responsible for process and plant technology at heinzelpaper, drew initial conclusions: “Compared to all other screening profiles that we’ve used so far, sticky removal has on average significantly improved. Losses in fine screening have been minimized, enabling us to achieve a higher yield.” Previously, when choosing the right basket, paper manufacturers had to decide whether to focus on better pulp quality, higher throughput or increased operational reliability. With the C- bar Vertecs, these trade-offs are no longer necessary. A new profile geometry has made this possible: Regardless of which performance aspect paper manufacturers prioritize, C-bar Vertecs outperforms all previously known solutions in all relevant parameters. Depending on the individual focus, production volume can be increased by at least 20 percent, and sticky and dirt spot separation can be improved by up to 50 percent. “We have extended the operating window for fine screening and reduced the vulnerability of the screens to plugging. This means that the screening process can now also handle more difficult-to-screen raw materials with a higher thickening factor in a stable manner,” reports Hunstein.
