Improving press performance step by step at Thai Cane PM2
Jun 20, 2018
The main factors affecting press performance are press felts, roll covers and vacuum system. Changing any of them immediately impacts the others. Thai Cane Paper tackled press section problems in close cooperation with Valmet’s Laem Chabang Service Center and global experts.
Valmet is our partner and gave us good service and support for these improvements.”

Customer challenges
The mill had challenges in their PM 2 press section. Press felt life time was too short, dewatering was poor and sheets tended to drop of during pick-up or follow the top-ply wire and they had issues with felt marking.
Solution
A four-phase improvement project:
1. Focus on press felts and dewatering
Valmet Press Felt SPMs were installed. The felt matches the vacuum capacity and minimizes felt marking.
2. Optimizing the vacuum system
Perforated Uhle box covers were taken into use improving dewatering and enabling to close the extra vacuum pump.
