・ Post machine to final drum sizes.
Merits of this application
Plasmet T is a highly abrasion resistant coating when used on it’s own, and when coupled with glass fibre reinforcing, as in this application, builds strength and thickness to these worn sludge rollers.
Plasmet T is a machinable coating designed to achieve a smooth surface finish.
This high specification system ensures the long life of the rollers in this highly abrasive application.
An additional benefit with the refurbishment option is that, with the properties of Plasmet T, the life of the roller will now be greater than that of a new roller – adding to the cost benefits of using Corrocoat coating systems
Corrocoat Japan credentials etc
Using coating as a method of refurbishment has proved cost and time effective.
Traditional methods of welding and machining have a turn around time of weeks, and replacement is expensive. Corrocoat’s solution can be turned around in days and is around half the coat of a new roller.
