Corrugated paper has become one of a wide range of packaging materials used in modern packaging. High quality of corrugated paper machine line is the basis to improve quality, increase efficiency. With 34 years experience in paper manufacture machine and paper pulp machine, Leizhan has the rich experience and customized production to meet customers` needs.
Corrugated paper machine, also called fluting paper machine is to produce corrugated paper. The whole corrugated paper machine line has two components: pulping making line and paper making line.
To produce living paper production line, the raw material can choose commercial wood pulp, commodity paper, waste paper and so on.
Conveying raw materials by Chain Conveyor for pulping is the first step of pulp making line. Next, the waste paper will be pulped in the Drum Pulper or D Type Hydrapulper.
Then, as there are mass of impurities exist in paper pulp, High Density Cleaner will be used for removing staples, stones, glassed, etc. various waste paper pulp. To screen impurities in the pulp like gravel, scrap iron, dust and large ink particles, screen devices like Pressure Screen, Vibrating Screen will help to remove it.
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.
The process of paper making line contains: Forming part, Press part, Dryer part, Calender part, Rewinding part
Forming part: After the paper pulp come into the headbox, it can spreads along the fine pulp evenly on the felts, which spread along the top and bottom of rollers.
Press part: By pressing felts, it can squeeze out as much water as possible.
Dryer part: Dryers section is arranged in group to ensure it can be operate at a gradually slower speed to compensate for paper shrinkage as the paper dries. It will discharge the water content down to a level of about 6%.
Calender part: Calendering can help to make the surface of the paper more sooth and glossy. What`s more, It also can ensure consistent thickness of paper. The pressure given by the rollers applied to the web influences the finish of the paper.
Rewinding part: To make it easier for shipping and conveying, we use rewinder to shape it into rolls and use slitter to cut the product into multiple strips to meet customers` requirements.
Our whole corrugated paper production line can use commodity paper, waste paper and so on, to make lightweight, compression, puncture -resistance, shock-proof and easy processing corrugated paper.
This line includes 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 (such as waste packing box,waste office paper and so on) turn to fine pulp for paper forming on the paper machine.
