The DOUBLE ROTATOR grinding process involves drying, pregrinding, separating, fine grinding and renewed separating, all in one system.

The DOUBLE ROTATOR is not sensitive to feed size fluctuations and is suitable for grinding even the hardest and most abrasive materials with a very high moisture content (such as gold ore).

The mill’s division into two grinding compartments with central discharge and intermediate material separation permit optimum adaptation to the coarse and fine grinding requirements of the respective feed material.
