Frequent roll changes, cargo handling and grinding had been resource-intensive. By significantly increasing grinding intervals, we've achieved substantial cost savings and also improved crane and staff availability for other tasks across the mill. This has contributed to more stable operations and fewer unplanned shutdowns, hence supporting our commitment to efficient production and continuous improvement," Majer says. Longer roll change intervals have also had an impact on maintenance planning at the mill. "Previously, aligning roll exchanges with our scheduled shutdowns was a challenge. Thanks to the extended and more predictable lifetime of the new roll cover, we've significantly improved our maintenance planning. This enhanced predictability supports smoother operations and reduces disruption," Majer says. Valmet's support is much appreciated After installing the new Valmet Calender Roll Cover CL-W, the wearing resistance of the new cover technology led to faster wearing of the doctor blades.
