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 – throughput 360,000 (!) tons of rock per day.
