  • 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.
