| Nordberg concave change lifting rings |
Modifications to the primary crusher at Glensanda, a Nordberg 54-80, resulted in the fixed wear package now consisting of three rows of concave segments.
These segments require regular replacement, causing considerable difficulties in access and manual handling.
The engineering team sought to find a more efficient, safe and cost effective method of installing the replacement segments. The solution was to design a series of three lifting rings which allowed all of the segments to be lifted and installed as a group.
The rings were manufactured to be capable of lifting the specific number of concave sections for each row of segments into the gyratory machine. |
