01The brief
A full liner set for one shutdown
The copper ore mill had a single shutdown window to change every shell and head liner, so the whole set had to arrive complete and in order.
We cast the liners in Ni-hard to the mine’s pattern set and hardness specification, heat treated them and numbered every piece. The set was packed in fitting order so the crew could reline without sorting.
02What we did
Cast, hardened, numbered, packed
- Cast every shell and head liner in Ni-hard from the mine's patterns
- Heat treated to the specified hardness and checked on each liner
- Numbered every liner to the relining plan
- Packed the set in fitting order for a single shutdown
