Internal flow screen-paper pulp processing machine
Product introduction:

NLS type internal flow pressure screen (rotor on the outside of the screen drum) is a papermaking screening equipment with high screening quality, large capacity, and low pulp flow pulse. It is suitable for fine screening equipment for wood pulp, various straw pulp, and waste paper pulp. , It is especially suitable as a screening equipment in front of the paper machine.
working principle
The internal flow screen is a device that continuously selects materials under pressure in a completely closed state. During operation, the unscreened pulp under pressure enters the outside of the screen drum in a tangential direction from the pulp inlet pipe on the upper part of the machine body, with the help of the inside and outside of the screen drum. The pressure difference, the qualified pulp enters the screen drum through the screen slit (hole) under pressure, and is led out from the good slurry pipe at the bottom. The impurity of the slurry machine that cannot pass through the screen slit (hole) drops to the bottom and is discharged from the slag discharge pipe . The rotating fins on the outside of the screen drum can generate a gentle pressure to further improve the annular flow of the pulp, and generate negative pressure from the tail to backwash the screen slits (holes). It can prevent the screen slits (holes) from being blocked, so that the slurry can pass through the screen slits (holes) smoothly to ensure the continuous operation of the screening.
