All around the world, mines are having to work ore deposits with declining mineral contents. As a consequence, grinding plants in the minerals industry are being designed for ever increasing throughput capacities.
In this respect, the combination of POLYCOM high pressure grinding roll and ball mill represents technological competence for tomorrow's world.
Copper ore comminution in South America:
Twelve POLYCOM systems are used for primary grinding. Ten energy-saving, low-wear ball mills are used for the wet process final grinding. The system has a throughput of 360,000 tons of rock per day.
