earless drive systems for 4-foot SAG mill and two 2-foot ball mills with all associated power supply equipment. SIMINE gearless drive systems for conveyors Overland conveyor with gearless drive system commissioned at copper mine in Peru siemens HB series gearbox /mining siemens HB series gearbox /cement E2-F3-T1--7 Germany siemens HB series gearbox /mining Germany siemens HB series gearbox /cementFor the first time, large-scale belt conveyor system with gearless drives has been installed outside of Germany. ThyssenKrupp supplied the conveyor system and Siemens the gearless drive system for the Antapaccay copper mine in Peru. The end customer is Australian mining company Xstrata Copper. With conveyor speed of 6.2 / on belt 1,3 mm wide, approximately 5,2 / of copper ore can be transported over distance of about 6.5 km from the mine to the processing plant. The drive system consists of two low-speed synchronous motors, each with power rating of 3,8 kW, and the associated Sinamics SL1 cycloconverters, converter transformers, containerized -house, and related electrical equipment. Compared with conventional high-speed motor and gear units, this gearless drive solution enables the installa-tion of larger drives, increases reliability and efficiency, reduces maintenance effort, and delivers maximum availability. Siemens scope of supply also included the entire switchgear and gearless drive systems for 4-ft SAG mill and two 2-ft ball mills with all associated power supply equipment.
