Roll Corrugations

You will eventually need to get your rolls re-cut or re-corrugated. Roll sharpening can lessen your roll life, but RMS uses specialized techniques to maintain your roll diameter, therefore allowing your rolls to be re-sharpened multiple times.

When is it time to have your rolls sharpened?

Indications of rolls being dull:

• Can’t pull amps; meaning the rolls are not sharp enough to grab the material and pull it through, they lack traction.
• Material is building up on top of the rolls at a faster rate than when rolls were first installed.
• Machine is losing capacity and not processing the same amount of material as when rolls were first installed.
• Typically, the interval between roll sharpening/exchanges is constant; meaning that if you ran (x) amount of material through the mill (y) months ago and you needed a roll sharpening, then you can assume at the same amount of material you will need to sharpen the rolls again in (y) months. 
• Visual inspection of rolls shows bald spots on rolls where corrugations are worn down.
