Belzona® Provides Positive Grip To Drive Roller



General Industry (GIND)



Solids Handling Machinery (SHM)


Customer Location:

Fertilizer plant, Bulgaria


Application Date:

June, 2009


Application Situation:

Conventional rubber cladding conveyor drive roller (diameter 800 mm and length 1400 mm) for transporting fertilizer production



Pieces of rubber cladding were frequently torn away due to build up. In addition severe wear from excessive moisture, chemical attack and abrasive media was causing belt slippage.



Belzona® 1321 (Ceramic S-Metal)

Belzona® 9211 (Supergrip Aggregate)



Carbon Steel


Application Method:

Application was carried out in accordance with Belzona Know-How System Leaflet SHM-12. Belzona 9211 non-slip aggregate was embeded in chevron designed stripes coated with Belzona® 1321. For corrosion protection the rest non-protected areas were covered with Belzona® 3921.


Belzona Facts:

The whole application was completed in one working day for a fraction of the cost of conventional rubber cladding. The durable positive grip system eliminated belt slippage and protected drive roller from abrasion and corrosion. Similar Belzona positive grip systems applied since 2006 are still in good condition, while the original rubber cladding system was lasting less than a year.
