Generally cultural paper making use wood pulp,white shaving pulp, waste book paper,or waste newspaper as raw material, when we use book paper and waste newspaper as raw material, the pulping process is a little more complicated, we need to add deinking equipment to remove the ink particles in the pulp.

Pulping process Raw material: waste newspaper



Capacity: 100T/D

Working process Waste newspaper is broken to pulp by D type hydrapulper, the cleaner equipment(High density cleaner)remove heavy impurities in slurry, then go through coarse screening equipment(M.C. coarse pressure screen), Fine screening equipment and fractionating sreen,and then high-speed stock washer can remove ink particle, short fiber can be directly conveyed to Inclined Screen to increase the consistency of pulp, prepare for paper machine. Deinking Machine In hydrapulper add chemical reagents to deinking, and after fine screening there are Flotation deinking machine to remove the ink, light impurities and stickies, etc. And High-speed stock washer can wash and concentrat in various domestic and overseas waste recycled pulp, chemical pulp before or after bleaching. Removing ink particles, fillers and other small impurities from the slurry with high efficient.
