Screening
Coarse screening ensures pulp cleanliness for the smooth runnability of the screening stages. The Valmet coarse screening concept ensures minimal breakdown of impurities and high sticky removal efficiency. Clean pulp is produced with low energy and wear part consumption.
Fractionation selectively classifies the pulp to optimize board making potential and enables exclusively dispersing and refining of fibers that have high strength potential. This brings energy savings and secures and homogenizes the targeted pulp quality.
Fine screening reduces stickies and dirt specks by gentle screening and minimal long fiber loss.
Coarse screening
Valmet’s coarse screens are designed for all coarse screening applications in recycled fiber processing and stock preparation.
