Leizhan Paper Machinery Company, one of the Chinese leading manufacturer and supplier of pulp and paper making equipment for paper producers to produce high quality testliner/kraft liner paper. Leizhan engineer can design customized pulp and paper production equipment and tailored solutions for paper plant.
To produce high strength kraft liner/testliner paper, papermakers can choose commodity wood pulp, waste paper, white shavings, LOCC, OCC, AOCC, etc. as raw materials. The complete paper production line can be divided into two parts: Stock preparation line and paper production line.
Stock preparation line
Various kinds of pulp board, waste paper are conveyed into Drum Pulp for pulping by Chain conveyor. To remove and screen waste paper pulp, meanwhile, separating the light and heavy impurities from the pulp, you can choose High Density Cleaner, Mid Consistency Cleaner, Fiber Lip Screen or Low Density Cleaner.
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 production 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.
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.
