Quadra FNX Mining Ltd., a Canadian mining company, has commissioned Siemens to modernize the drive in an SAG mill in its Robinson open-cast copper mine in Nevada, USA. This will be the first time that an ore mill is to be equipped with a Sinamics SL150 cycloconverter, after this new drive system has already been successfully introduced in other mining and metal applications as bucket chain excavators and rolling mills. Together with a new diagnostics system, the cycloconverter will increase the operational reliability and availability of the plant while at the same time reducing maintenance costs.
