Refurbishments & Relocation of Pre-Owned Mills
When you need a new mill, budgetary or time constraints may be a limiting factor. We can refurbish and modify your mill or convert a previously-owned unit to meet your specific needs. For example, a ball mill may be converted into a SAG mill or a rod mill into a ball mill.
Refurbishment is treated as a turnkey project – starting with the removal of your mill, redesign work (when required), where it moves on to the manufacturing of replacement equipment, meticulously renovating mill components, transportation, installation, commissioning, and maintenance.
