Roll Grinding

Run at faster speeds, have more balancing accuracy, improve the runnability of rolls — all with PRG.

PRG has a rich history in the paper industry. And as a result, we have comprehensive understanding of it. From wet-end to dry-end, from the recovery area to converting, PRG regrinds and refurbishes rolls, spools, drums, pulleys, dryers, and trunnions from the lime kiln. Our roll grinding experts will help return your rolls to the proper roundness, concentricity, shape, profile match tolerance and surface finish — ensuring they exceed OEM specification.   

We’re capable of holding tolerances down to +/- 20 millionths of an inch with our equipment, allowing us to meet your mill’s needs, not only for tight tolerances, but also, faster running speeds and more accuracy in balancing. In addition, our tight tolerances in paper mill rolls solve a lot of common industry-wide problems:

  • Wet streaks
  • Inconsistent profiles
  • Variations in thickness
  • Barring, vibration
  • Wasted raw materials
  • Increased costs
  • Reduced profit

 

We can work with your mill to propose other money-saving initiatives as well:

  • Create a maintenance plan that works around your schedule
  • Guarantee faster, easier emergency repair in the event of unforeseen issues
  • Work with your Operations Managers and Maintenance Supervisors to identify any possible areas of concern
  • Suggest money savings – like Roll Armor™
