Start up of the HPGR project is scheduled for the 4th quarter 2010. ABBs scope of supply comprises a medium voltage (MV) variable speed drive system that includes two motors, two transformers, and two MV ACS1000 water cooled converters for the High Pressure Grinding Rolls. The drive system has a power of 2 x 2500kW.
High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain size.
