“Before liner tooling is made, sophisticated
CAD systems are used to generate liner models.
These models will be used to create an assembly
drawing to assure all castings fit. The model is
also used by pattern makers on the equipment.
In addition, the models will be used to study
solidification patterns that develop when large
castings cool. This helps determine how molten
metal will be fed into the mould cavity, and
where critical risers need to be located to assure
that the liner is internally sound and free of
voids.”
On the other hand, grinding media can be seen
as the ‘partners’ of liners inside the mill. ME
Elecmetal’s grinding media offering includes
forged steel balls and rods for SAG, ball and rod
grinding mills. ME’s forged steel balls can be
made up to 6.5 in diameter, with its products
“suitable for the aggressive environment found
inside large SAG mills where high energy impacts
are very common.”
This partnership between large liners and
large grinding media is described as the key to
improved milling operations. “All these huge
parts we make are supported by our ME FIT
System service offering, which includes 3D laser
scanning, DEM and FEM simulations; reline
simulations; and ME Grinding Apps.”
As mentioned, ME Elecmetal recently officially
inaugurated the Rancagua foundry
modernisation project which will increase its
production capacity to 36,000 t. The project
includes a new special steel foundry; an
advanced laboratory for grinding media
