60 % of the high-pressure grinding rolls installed in the minerals industry are from Polysius: the POLYCOM® operates convincingly all around the world, comminuting • copper ore • gold ore • iron ore • diamond ore • platinum ore • coal • granulated blast furnace slag • limestone • cement clinker and • other mineral raw materials.
This type of mill offers the minerals industry numerous benefits:
- Low operating expenses: in comparison to other systems, both the power consumption and the costs for wear parts are significantly lower.
- High throughput rates: a high-pressure grinding roll can replace several reduction crushers.
- Metallurgical advantages in the downstream process stages.
- Shorter delivery and commissioning times than can be achieved with other systems.
POLYCOM® units are designed for throughput rates in excess of 3,000 tph. The mill feed material can be dry or moist and with particle sizes ranging from below 1 mm to more than 75 mm. If required, the material can be dried in screens or air separators in a closed circuit grinding system.
