The rubber edge seal on the rotating screen wheel had, over many years, worn the steel mating edge in the chamber

 
 

Products:

Belzona® 1311 (Ceramic R-Metal)

 

Substrate:

Steel

 
 

Application Method:

Belzona Facts:

Welding was being considered but this would have taken several weeks to complete as it would have involved removing the edge plates, welding and re-machining. The Belzona application was completed in-situ and in a fraction the time the welding option would have taken. Twenty-eight kilograms of Belzona® 1311 were used in the application.
