Introduction
This production line can use waster paper,recycled paper ,tree ,bamboo ,reed ,wheat straw cotton
and bagasse as raw material to make good quality craft paper,finished product can be paper roll,
tissue paper, toilet paper, culture paper , Kraft paper, newspaper etc..
the main work flow is as follows:
1 pulp making production line
2 glue adding system
3 paper making production line
4 paper converting section
5 boiler section
Raw material
Main Equipments
1.Paper Machine Wire Section
At the wet end of the paper machine sits the headbox, which distributes a uniform jet of watery stock. The liquid falls onto the wire or forming fabric. Beneath the wire, foils (short for hydrofoils) remove water and improve fibre uniformity, ensuring that the fibres weave together in a tight mat. The wire passes over suction boxes that vacuum out the water, leaving a soft mat of pulp that forms the paper sheet, also known as the paper web. By now the wire has travelled 30-40 meters. In a couple of seconds, the water content has dropped to 75-80%, and the web has lost its wet sheen.
2.Paper Machine Press Section
The next stage of water removal consists of passing the paper web through a series of nip rollers that squeeze the water out of the pulp mat. This pressure also compresses the fibres so they intertwine to form a dense, smooth sheet. At this stage, the water content has reduced to between 45 and 55%.
3.Paper Machine Drying Section
The paper web now travels through an enclosed space containing a number of steam-heated drying cylinders. They are warmed up to 130ºC using steam heat to ensure that the paper is now 80 to 85% dry. Wet sizing solution is now applied to the paper in order to add a thin layer of starch to the surface. Starch contributes to stiffness and the bonding of the fibres within the sheet of paper. After the sizing is applied, the paper passes through another set of heated drying cylinders. In all, the paper web may travel 400 meters through the dry end. In the process, it will lose roughly 93% of its water.
4.Paper Machine Finishing
To give the containerboard a smooth and glossy surface to optimise it for printing, the paper passes through a set of smooth rollers, which can be hard or soft, that press the paper, embossing a smooth face on the paper surface.
5.Paper Machine Winding
After completing its 500-metre journey, the paper exits from the paper machine and is automatically wound onto a jumbo reel, which can weigh 50 tonnes and be up to eleven meters wide. The jumbo reel is lifted by crane to a nearby winder, where the paper is unwound and cut into smaller rolls as required by the customer.

We are the best one in the paper industry!
We can make the optimization proposal after analyzing and figuring out the problems of the paper production line according to the papermaking progress, equipment, electric automatization etc.
We can make the machine speed to run in the best condition and put the manufacture cost down to the bottom while ensuring the good quality.
During the process of producing or increasing machine speed
Blocking wire section, poor dewatering of the press section, frequent breaking paper, but badly surplus capacity of the dryer section…
Wire section, press section and dryer section is running normally, but the sizing part always goes wrong…
When the cost of partial modification is not so good, we have to consider - to replace of it !
We can supply the matched and higher performance
Wire Section: Cylinder type, Fourdrinier type
Press Section: 3 rolls 2 press type, 4 rolls 3 press type
Dryer Section: various kinds of capacity and type
Sizing Section: horizontal type, indented form, film transfer type
Reeling Machine: every kind of reeling machine, horizontal type
Multiform tensioner, corrector, scraper, shower pipe, water box, scraper blades, forming board…
Every kinds paper tester
The paper machine is made of rolls and base frame.
And the output stability and efficiency of the paper machine is based on the quality of the rolls and other necessary parts.
We are focusing on all parts of pulp and paper industry!
