Belzona® Protects Hog Fuel Screw Conveyor



Pulp & Paper (PLPR)



Solids Handling Machinery (SHM)


Customer Location:

Montana, USA


Application Date:



Application Situation:

The raw wood supplied to this Pulp and Paper Mill used to burn in the Boiler for process steam was transported to the Boiler house via this auger. The abrasive nature of the media would wear the base of the flighting on this auger.



The worn auger would be replaced periodically due to the flights being too thin. The manufacture and replacement of these augers were expensive. The life of the auger was hard to predict due to the varying raw material supplied and the changing demand. Downtime was not a good option when supplying the critical nature of the Boilers.

Belzona 1812 (Ceramic Carbide FP)



Carbon Steel


Application Method:

The application was carried out in accordance with Belzona Know-How System Leaflet SHM-14 and Belzona product Instructions For Use.


Belzona Facts:

Because of the critical nature of this equipment, a spare auger shaft or screw conveyor was kept on standby. This allowed the application to be performed with no downtime. Because the auger could be coated on site, the cost of protecting and improving the auger far outweighed the replacement and shipping costs of the auger.
