How to deal with tailing of the first stage coarse screen, paper pulp equipment

how-to-deal-with-tailing-of-the-first-stage-coarse-screen Recently we have described about the coarse and fine screen. This article will focus on how to deal with tailing of the first stage coarse screen. It mainly use Light Impurity Separator and Reject Separator. They work together to remove the impurities in tailing slurry and make it clean again.

Light Impurity Separator and Reject Separator

Light Impurity connect with two main pipes and a tank: inlet pipe, outlet pipe and heavy impurity tank. Slurry
enters in a tangential direction, and rotates along inwall. Fine slurry is discharged to coarse screen pulp chest/agitator, heavy impurities are discharged into the heavy impurity tank. The tailing containing light impurities get together to the hole on the top of Light Impurity Separator, and enter the Reject Separator, which mainly applies to remove light impurities. The fine slurry of Reject Separator enter the Light Impurity again from inlet pipe, so that it can be completely cleaned.
Waste paper pulping is a complex process, it is constituted by various kinds of equipment, and each of them has their own effects. Sometimes the slurry was handled by the same equipment more then once. One side the paper pulp can be totally cleaned, what’s more, the tailing can be used after ulteriorly purification , which increase pulp quantity and reduce investment.

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.
