30T/18H Duplex Board Production Line

Raw material: Waste paper

Line: whole 30T/18H duplex board production line

 30T/18H duplex board paper pulping process:

Firstly, recycled paper will be conveyed into the ZDSD23 D type hydrapulper for pulping.
Secondly, ZSC4 high density cleaner will be used for removing staples, stones, glasses from the slurry.
Thirdly, pulp will be transported into ZNS0.3 mid consistency coarse screen for coarse screening. After coarse screening, tailing pulp will be processed by PZ2 reject separator.
Then, ZNS0.6 mid consistency fine screen will be used for fine screening of paper pulp.
After fine screening,pulp will be conveyed into ZDP450 double disc refiner for improving the beating degree and pulp quality.
Finally, NLS0.6 inflow pressure screen before paper machine will be used for the last step of pulp processing.
