Dryer section grindings and coatings

PR Rolls provides professional dryer cylinder grinding and coating services directly on site in the paper machine. This means the cylinders do not need to be removed, reducing downtime, avoiding unnecessary dismantling work, and helping the mill return to production faster.

Our on-site service restores the dryer cylinder surface to the required condition, improving runnability, heat transfer, sheet quality, and coating performance. The work is carried out with specialized equipment designed for use inside the paper machine, ensuring accurate results even in demanding mill environments.

PR Rolls can also perform multiple grinding and coating operations at the same time, making the service especially efficient during planned shutdowns and maintenance stops. This enables mills to restore several dryer cylinders within the same service window and minimize total downtime.

Benefits of on-site dryer cylinder grinding and coating:

• Performed on site in the paper machine
• No need to remove the dryer cylinders
• Possibility to grind and coat multiple cylinders simultaneously
• Reduced downtime and maintenance costs
• Improved cylinder surface quality
• Better paper machine runnability
• Extended lifetime of the dryer cylinders
• Suitable for planned shutdowns and maintenance stops
