A drive system that has been synonymous for years with virtually wear-free operation. The concept eliminates all mechanical parts between motor and mill. Fed with variable frequency from a fuseless short-circuit-proof cycloconverter, SIMINE MILL features the highest operating efficiency of any variable-speed drive available – leading to reduced mill downtimes and substantial energy savings.
When it came to installing three ball mills and two SAG mills in El Teniente, Codelco opted for a complete solution with SIMINE MILL, covering everything from manufacture to commissioning. The amortization period was extremely short thanks to very high system availability and substantially lower maintenance costs.
