paper-stock-screening

Comparing with pulping process, paper stock screening is harder. Its aim is to remove impurities and manufacture homogeneous slurry. It can also disperse fibers.

Source of Impurities in Paper Stock

1.The impurities brought by raw material;
2.Slurry hasn’t been clean screen;
3.Brought or produced during conveying and reserving processes;
4.Brought by the wearing of pulping equipment.
5.Undesirable cook

Harmful Effect of Impurities in Paper Stock

1.Equipment Wearing;
2.Paper quality decrease;
3.Negative influence for paper making.

Paper Stock Screening Equipment

Regular paper stock screening equipment is Pressure Screen.It has below advantages;
1.High screening and cleaning efficiency, low fine pulp proportion in slag slurry;
2.Adopt closed equipment to prevent carrying or making froth;
3.Cover a small area, low power consumption;
4.Strong adaptable capacity. It can remove impurities of different shape and density.

Corrugated Paper Making Line

Corrugated Paper Making Line needs Chain Conveyor, Drum Pulper, D Type Hydrapulper, Mid Consistency Pressure Screen, Double Disc Refiner, Inflow Pressure Screen, and so on. Paper pulp machine used to make waste paper turn to fine pulp for paper forming on the paper machine. Leizhan plays great emphasis on designing most suitable Corrugated packaging paper manufacturing solutions for corrugated packaging paper makers.

Cultural Paper Making Line

Cultural paper machine line: Firstly, Raw materials are conveyed by Chain Conveyor into Drum Pulper for pulping. Then, High Density Cleaner helps to remove heavy impurities. What’s more, we need to improve slurry beating degree by using Double Disc Refiner. Eventually, the waste paper turn into fine pulp after a series of screening and deslagging and it will be conveyed into Headbox for paper making.
