The role of the vacuum suction box in the paper machine-Jinling Paper Equipment

　　Jinling Papermaking Equipment:

　　After the slurry passes through the dehydrated originals such as the table roll and cutting board on the screen to remove most of the water, the fibers are gradually deposited into a wet paper web. As the concentration of the wet paper web increases, the dehydration resistance increases, and the high pressure difference of the vacuum suction box must be used to force the dehydration. Before the wet paper web reaches the vacuum suction box, its dryness is about 2%-3%, and the dryness after passing through the vacuum suction box can generally reach 8%-12%.
