Belzona® Keeps Basalt Lined Deflaker Operational

 
 

Industry:

Pulp & Paper (PLPR)

 
 

Application:

Solids Handling Machinery (SHM)

 
 

Customer Location:

Containerboard Paper Mill, North Alabama

 
 

Application Date:

March, 2007

 
 

Application Situation:

This deflaker is used to spin trash (staples, plastic, glass, metal, etc.) out of recycled cardboard. The inside is lined with basalt tiles. This is a one of a kind machine.

 
 

Problem:

If this unit fails, there is a huge expense in acquiring another. Task was two fold, to line the inside with a sacrificial product and rebuild the door lip so the bolts would not pull out.

 
 

Products:

Belzona® 1812 (Ceramic Carbide FP)
Belzona® 1111 (Supermetal)
 

Substrate:

Basalt tiles and Stainless steel

 
 

Application Method:

The application was carried out in accordance with Belzona Know-How System Leaflet SHM-13. We used aluminum oxide blast material to achieve a desired profile and applied 1/4" of Belzona® 1812 around the entire interior of the equipment. We also applied Belzona 9411 (Release Agent) on the bolts, seated them, and rebuilt the door edges with Belzona® 1111.

 
 

Belzona Facts:

The alternatives the mill had were to try and find another piece of similar equipment or remove the tiles and try relining the equipment with more tile. We offered them another alternative in that we would lay Belzona® 1812 over the tiles to act as a sacraficial layer. We now have a yearly project during their shutdowns.
