The new PrimeFilter D is the latest ANDRITZ innovation in thickening and fiber recovery, enabling the mill to handle higher feed consistencies and higher-freeness pulp, even in the most demanding applications, while in parallel offering significant improvements in terms of operation and maintenance.

Malaysia Lee & Man Paper ordered a total of 15 PrimeFilter D disc filters for their four kraft paper production lines, applied as stock thickener and saveall disc filters in the white-water system of the PM water loops. After successful start-up of the first eight units, start-up of the remaining seven machines is planned to be accomplished by the end of the year.

Chen Liming, Project Director, Malaysia Lee & Man Paper, comments: “The new PrimeFilter D disc filters are able to handle higher-freeness pulp at our mill, which is especially important for kraft liner stock preparation. In parallel, the CC Bagless sectors used enable excellent operation in terms of fiber mat build-up as well as fiber mat knock-off, and we also expect a significantly reduced maintenance effort. The two-level shaft sealing is easily accessible and combines superior filtrate quality with highest reliability. This is a convincing package that will help us to run our production very efficiently in the long term.”

Malaysia Lee & Man Paper Manufacturing Limited, established in May 2018, is one of the production locations of Lee & Man Paper Manufacturing Ltd. and has four wet pulp production lines and four paper production lines, with an annual capacity of 300,000 tons of packaging paper.
