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:
Four POLYCOM systems are used for primary grinding. Four energy-saving, low-wear ball mills are used for the wet process final grinding – throughput 108,000 (!) tonnes of rock per day.
