Vilter Cool Compression Mono Screw
We have one customer with a Vilter Cool Comression mono screw. During their 5000 hour check, they've notcied the gaterotor edges are chipped and the ends look as though they are delaminating.
I've read a couple of threads talking about possible backspin and possible passing too much liquid.
Any updates on causes and/or solutions? The "solution" from Vilter is that it's normal wear and tear. They've buttoned it back up and put it back in service as is.
I'll post images later.
