Shandong Huatai Paper starts up PM 11 after rebuild

Shandong Huatai Paper and Voith Paper successfully started up PM 11 in the eastern Chinese province of Shandong. PM 11, a former newsprint machine, was successfully rebuilt for the production of high-quality graphic paper. The machine's web width is 10.2 meters and the design speed 1,800 m/min. With the help of leading Voith technologies, the annual capacity of the rebuilt PM 11 can be increased from 400,000 to 520,000 tons.

The customized rebuild includes a variety of state-of-the-art technology solutions with a focus on stability, reliability and efficiency. The solutions not only help to extend the service life but also lead to more sustainable and cost-efficient operation.

This involves upgrading the MasterJet Pro G headbox and implementing the optimization of dilution water technology to improve paper quality while reducing energy costs. The Voith experts upgraded the forming section similar to the DuoFormer concept for optimum formation and higher throughput. In addition, the ParaSlice nozzle concept and the EdgeModule system were integrated to stabilize the fiber orientation profile (CD profile). The newly installed ProRelease+ HighEnd boxes in the pre-dryer section significantly increase the vacuum level, ensuring the stability of the paper web at high speeds and minimizing the risk of paper breaks.

In addition, a SpeedSizer AT with its uniform film application ensures even and high-quality paper profiles. The CombiDuoRun dryer concept and an efficient new dryer section hood are used in the after-dryer section.
