Video: Building the world's largest HPGR

The HRC HPGR is fed with the secondary cone crusher product and has a F80 of 26 mm and a top size of 50 mm. The HRC HPGR is in a closed circuit with an 8 mm wet screen, and feeds two 7.3m (24 ft) ball mills. Due to diminishing ore grades and rising energy costs, the mining industry has been driven to find more energy efficient solutions.
