Belzona® Keeps Sawmills Running Efficiently With Its Positive Grip System

 
 

Industry:

Pulp & Paper (PLPR)

 
 

Application:

Solids Handling Machinery (SHM)

 
 

Customer Location:

Sawmill in British Columbia, Canada

 
 

Application Date:

1996 - Present

 
 

Application Situation:

First cut bridge planer rolls at a sawmill in British Columbia.

 
 

Problem:

The sawmill planer bridge rolls are usually welded or cross-hatched to effectively grip and transfer the lumber. These rolls wear relatively quickly from abrasion, which reduces the throughput and/or quality of the cut lumber.

 
 

Products:

Belzona® 1321 (Ceramic S-Metal)

Belzona® 9211 (Supergrip Aggregate)

 

Substrate:

Steel

 
 

Application Method:

The application was carried out in accordance with Belzona Know-How System Leaflet SHM-12.

 
 

Belzona Facts:

These rolls are typically in service for 3-5 years depending on the particu-lar saw mill activity and type of lumber produced. Initially the aggregate will come off, but after a few minutes of operation, no more material will be removed from the rolls.
