Voith upgrades disk filters at WEIG-Karton – significantly improved filtrate values after rebuild
The new filtrate valve ensures a consistently high vacuum and further ensures the high filtrate quality. The rebuild switched the mounting by plain bearing to reliable roller bearing with the new central shaft. In addition, the disk filter was equipped with new knock-off and cleaning spray pipes featuring patented nozzles.
The upgraded disk filter now replaces four drum thickeners, which had become susceptible to failure due to high screen wear.
WEIG-Karton’s trust in Voith is based on many years of collaboration. Two years ago another third-party disk filter had already been successfully rebuilt to BaglessPlus sectors and HiCon. Thanks to the conversion to HiCon, this disk filter is now being operated at an intake stock consistency of up to 2%.
The Voith disk filter technology has been developed for BlueLine, a product and component range designed to keep energy, fiber and water consumption in stock preparation as low as possible. Voith disk filter components can be installed in machines from all manufacturers.
