Application Situation

This is one of the biggest non-ferrous refineries in Europe. It has been in operation since 1980 with seven ball mills continuously working ever since. The ball mills are used to grind and blend materials, reducing their size by impact as the balls drop from near the top of the shell. Wedge liners protect the shell from damage.

Application Method

The application was carried out in accordance with Belzona Know-How System Leaflet TCC-9.

Belzona Facts

Belzona 4111 was applied to resurface the shell and fill the gaps in the wedge liner. First application was completed in 2016 onto two ball mills, followed by two more in 2017 and another two ball mills in 2018.
