Belzona Extends Life Of Pulp Blender



Pulp & Paper (PLPR)


Áreas Know-How:

Engines and Casings (ENC)


Cliente / ubicación:

Paper mill, Spain


Fecha de aplicación:

January 2007


Situación de aplicación:

Outlet pipe of an industrial blender



Pump and bolt threads were severely damaged by the highly abrasive stream of shredded paper pulp flowing through it



Belzona® 1111 (Super Metal)

Belzona® 1812 (Ceramic Carbide FP)





Método de aplicación:

Application was carried out in accordance with Belzona Know-How System Leaflets ENC-2 & SHM-11. The casing threads were reformed with Belzona® 1111 using the bolts treated with Belzona Release Agent as formers. The internals of the pipe were lined with Belzona® 1812.


Hechos Belzona:

Prior to contacting Belzona, the company had to replace this piece of equipment every 1 or 2 years. An inspection of the Belzona lining 3 ½ years later, in August 2010 showed it was still in place and none of the metal parts were exposed. As a result, the customer asked Belzona for several similar applications.
