Coating board paper machine line

Coating board paper machine line


Coating board paper machine encompass two parts: pulping making line and paper making line.

Raw material

Coating board paper manufacture machine uses waste paper, wood pulp and white shavings as material to make high quality Coating board paper.

Pulping making line/stock preparation line

To make fine paper, the waste paper should be dissolved into pulp. Firstly, waste paper can be conveyed to the Drum Pulper for pulping through Chain Conveyor. After waste paper is conveyed into the Drum Pulper or D Type Hydrapulper, the paper machine can continuously pulp and preliminary screen the impurity of the waste paper. Then the impurities is cleaned and removed by a series of stock cleaner and screening machine. Such as: High Density Cleaner, Inclined Screen, Pressure Screen, etc.
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.

Paper making line

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.

Finished paper
Coating board paper production line can produce high quality Coating board paper with waste paper, wood pulp and white shavings.
