2 DRIVE YSTEM OR HIGH PRESSURE GRINDING ROLL ROLLXTEND™ Application challenges Today''s highly competitive mining industry calls for continuously operating, high throughput equipment, such as the HPGR, to be designed for maximum availability and reliability. A HPGR''s optimum point of operation is widely influenced
Thus, some of the finish grinding work is handled by the highpressure grinding roll. The throughput of the existing grinding system can be increased by 50 to 70%, while power consumption can be cut by 20 to 30%. Additional options for highpressure grinding roll use in gold ore comminution circuits are illustrated in Figure 11.
When the highpressure grinding roll is combined with a ball mill, the polycom achieves energy savings of up to 40 percent in comparison with conventional ball mill systems. In the case of existing plants, output can be increased by more than . 6 .
