Perfecting Hard-Rock High Pressure Grinding Performance

The authors commented that the HPGR in quaternary mode is a powerful tool for capacity increase and that efficient classification is the key for further energy savings. However, tertiary plus quaternary HPGR use is less efficient than fine screening at the tertiary stage, while the limits on fine wet screening have yet to be determined.

First choice for HPGR technology and service

HPGR grinding significantly enhances overall throughput. This results in the creation of a large proportion of finished product and the reduced Bond Work Index of the pressed material. This generally allows for a reduction in the projected number of equipment units in tertiary crushing, quaternary crushing and grinding. Operating principle
