How energy efficient is HPGR?

The advantage of employing a single HPGR unit was first seen in a Chilean iron ore mine. There, one HPGR is operated in closed circuit to produce more than 1 000 tph of –6 mm product from a 65 mm feed material. The lifetime of the wear protection was more than 8 000 hours. Power consumption was about 1.3 kWh/t. It was the substitution of
