Refurbishment Your Way

PRG offers four service options to meet your plant’s needs:

  • Send the entire machine to PRG for complete refurbishment.
  • Send rolls, gears, hopper side plates, bearings and housings.
  • Send rolls, gears and hopper side plates.
  • Send just the rolls to be inspected, cleaned, ground and de-scaled. PRG will then re-cut the face lengths and polish journals.

When the time comes for a new or replacement refiner, PRG will even help evaluate machinery before purchase.

PRG’s service begins with a consultation at your facility. If you experience any of the following issues with your chocolate or refiner, give us a call. The consultation is absolutely free.
