Application Situation

Screw conveyor used to skim sludge from the base of a silo at a biomass plant.

Application Method

The application was completed in accordance with system leaflet SHM-14. The screw conveyor was grit blasted to SA2 1/2 with a minimum surface profile of 3 mil (75 microns). The area to be coated was then cleaned and degreased using Belzona 9111. Belzona 1814 was applied by brush to the entire area of the conveyor to provide long-term protection against heavy abrasion.
