Belzona® Prevents Costly Leakage



General Industry (GIND)



Gaskets, Seals and Shims (GSS)


Customer Location:

Cement plant, Bulgaria


Application Date:

March, 2008


Application Situation:

Ball Mill used to grind limestone for cement production.



The ingress of limestone particles into the 10-20mm gap between the tubular screw conveyor and its housing leads to wear and leakage of milling media outside the mill.



Belzona® 1812 (Ceramic Carbide FP)


Carbon Steel


Application Method:

Application was carried out in accordance with modified versions of Belzona Know How Leaflet GSS-9 and VPF-2.


Belzona Facts:

The Belzona was chosen in order to prolong the life of tubular screw conveyor. The customer had used different epoxy-based products to solve the problem but with limited success. Welding was not considered due to high cost and stress buildup. The Belzona solution proved to be much easier and faster to apply saving the plant more than 5000 euros in replacement and maintenance costs.
