Metso Paper supplied Guangzhou PM 8 started up after an extensive rebuild

Guangzhou Paper Co., Ltd. PM 8 has been successfully started up on 6th of September in Guangzhou, China, after an extensive rebuild made by Metso Paper. The purpose of the rebuild was to improve the paper quality, especially formation and porosity, as well as the runnability at the press section in order to reach the design speed of 1,100 m/min.

The rebuild of the former to a BelBaie V shoe blade former will improve the drainage and formation as well as minimize the two-sideness of the paper web. In addition, this solution will increase the paper machine's operating speed in a very cost-effective way.

The rebuild also included a SymBelt shoe press, felt change equipment for the press section, dryer section modifications, rebuild of the existing calender to an OptiSoft calender, as well as some auxiliary modifications of the process.

"After the rebuild, PM 8 can be run with a new grade of 45 g/m2 with excellent quality properties. We are optimistic to achieve also all the other targets we have set for this project", Ms. Wang QiuChang, Project Manager of Guangzhou Paper PM 8 says.

Project Manager of Metso Paper, Pentti Nauha, states: "We have been able to maintain the tight schedule for the project. The co-operation with the customer has been a success."
