Paper Industry

PRG has a rich history in, and an understanding of, the paper industry. 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.

Tight Tolerances in paper mill rolls will solve a lot of problems in the industry: wet streaks, inconsistent profiles, variations in thickness, barring, vibration, wasted raw materials, increased costs and reduced profit.

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 speed, more accuracy in balancing and improved runnability of rolls.
