The press rolls were upgraded with Valmet Press Roll Cover PP premium polyurethane roll covers.
|The goal was to improve roll cover durability and reliability and also to boost dewatering by increasing the nip load.
The clearly higher nip loading has improved dewatering, and web dryness in the press section has increased from 49 to 51 percent.
The rolls can be operated without internal water cooling and the rolling resistance is lower resulting in energy savings.
The investment paid for itself in less than eight months.
