At BEP, we do everything we can to receive, inspect, repair and return damaged rolls as effectively and efficiently as possible. We understand the costs of downtime, which is why we advise our customers to keep spare rolls.

The initial repair procedure is to remove the damaged material by turning and grinding, so that we are down to a clean shaft. It then needs plating with nickel to build back up the diameter, followed by chrome plating to provide the hard-wearing longevity for future use.

BEP Surface Technologies offer an internal cleaning service for all Chilled and Heated Rolls. Hot acid is pumped through the roll for 24 hours, then neutralised and flushed with water.
